Issues

  • CWS sb103, integrated in OOO310_m1 and DEV300_m42:
  • CWS sb107, targeting OOo 3.2:
    • Issue 99519 “Remove unnecessary library dependencies” (“[t]his cleanup has no positive impact on OOo startup performance though”—[1])
  • analyzing startup to identify performance problems (ongoing)

Details

Additional processes during startup

Starting OOo DEV300m39 unxlngi6.pro on v20z-so3 (some old Ubuntu machine), soffice.bin spawns additional processes during start up: 

$ strace -fF opt/openoffice.org3/program/soffice.bin 2>&1 | grep 'exec.*('
execve("ooo/opt/openoffice.org3/program/soffice.bin", ["ooo/opt/openoffice.org3/program/"...], [/* 17 vars */]) = 0
[pid 19800] execve("/usr/lib/libgconf2-4/gconfd-2", ["/usr/lib/libgconf2-4/gconfd-2", "17"], [/* 18 vars */] <unfinished ...>
[pid 19802] execve("/bin/sh", ["sh", "-c", "sh -c paperconf 2>/dev/null"], [/* 18 vars */]) = 0
[pid 19803] execve("/bin/sh", ["sh", "-c", "paperconf"], [/* 17 vars */]) = 0

It turns out only the first additional process (/usr/lib/libgconf2-4/gconfd-2) is spawned directly from soffice.bin (and the following ones are in turn spawned from that process), and it is spawned during a call to gconf_client_preload:

The first call to gconf_client_preload (that presumably does the spawning) accounts for 0.05 seconds of real time during start up:

The overhead of the soffice wrapper script around soffice.bin is roughly as follows (see issue 97491 “"soffice" now being binary instead of shellscript” for temporary problems with the soffice wrapper script), where javaldx and pagein are among the executables called from the script:

ELF Dynamic Objects

At least on ELF based systems, one factor that controls how much of a dynamic library needs to be loaded in initially are the relocations in the .rel.dyn section (the .rel.plt section is not relevant directly at load time unless you force LD_BIND_NOW). The following gives the number of relocations per ELF dynamic object in a DEV300m41 unxlngi6.pro OOo installation (libicudata.so.40.0 has no relocations), for some rough guiding numbers: 

$ cd DEV300m41-unxlngi6.pro-en_US && find opt -type f -exec bash -c 'file "$0" | fgrep -q " ELF " && echo $(readelf -r "$0" | grep "^Relocation section .*rel.dyn" | cut -d " " -f 8) "$0"' {} \; | sort -n

Measurements

Measurements are done on a Sun Ultra 20 with a recent (as of February 25, 2009) Debian Unstable i386. The OOo is a sb107/DEV300/src.m41/instsetoo_native/unxlngi6.pro/OpenOffice/archive/install/en-US/OOo_3.0.0_090219_unxlngi6_install.tar.gz (i.e., CWS sb107 as based on DEV300m41 with just a fix for Issue 99519 included), installed to /sb-tree1/ooo-m107 with UserInstallation=file:///sb-tree2/ooo-m107/.openoffice.org/3 in /sb-tree1/ooo-m107/openoffice.org3/program/bootstraprc and “Check for updates automatically” disabled; the working directory is /sb-tree3.

time

Just after system start up run 

$ cd /sb-tree3
$ time /sb-tree1/ooo-sb107/openoffice.org3/program/soffice -swriter # press Ctrl-Q as soon as the text cursor starts to blink
$ time /sb-tree1/ooo-sb107/openoffice.org3/program/soffice -swriter # press Ctrl-Q as soon as the text cursor starts to blink
$ time /sb-tree1/ooo-sb107/openoffice.org3/program/soffice -swriter # press Ctrl-Q as soon as the text cursor starts to blink

to get one cold and two warm start-up (plus shut-down) times. Repeat three times. The average of the three cold start ups is 

real 0m11.584s
user 0m2.335s
sys  0m0.237s

and the average of the six warm start ups is 

real 0m3.528s
user 0m2.069s
sys  0m0.173s

strace

Just after system start up run 

$ cd /sb-tree3
$ strace -ff -T -o ~/cold /sb-tree1/ooo-sb107/openoffice.org3/program/soffice -swriter # press Ctrl-Q as soon as the text cursor starts to blink
$ strace -ff -T -o ~/warma /sb-tree1/ooo-sb107/openoffice.org3/program/soffice -swriter # press Ctrl-Q as soon as the text cursor starts to blink
$ strace -ff -T -o ~/warmb /sb-tree1/ooo-sb107/openoffice.org3/program/soffice -swriter # press Ctrl-Q as soon as the text cursor starts to blink

to get one cold and two warm start-up (plus shut-down) times. Repeat three times (cold1–cold3, warm1a–warm3b). Use 

$ for i in cold1.*; do sed "s/^/${i#cold1.} /" "$i"; done | strace-eval > cold1-all

to group system calls by the files or file descriptors they work on. The output is a list of blocks, sorted descending on time spent. Each block consists of a start line consisting of a file tag, a colon, a space, and an accumulated time, followed by one or more lines (pertaining to the given file tag) from the (combined, in the case of strace -ff -o) original strace output (in original order), each prefixed with a space. A file tag is either a filepath in double quotes, or a pid/fd combination of numeric pid and fd (for uses of file descriptors that cannot be associated with a filepath; the “pid/” part is left out for strace calls without -ff), or ??? for all system calls that are not associated with a filepath or file descriptor at all. The accumulated time is the sum of the times given by strace -T for the individual lines, measured in microseconds.

For the measured times, take the following into account:

  • The description of the -O option on the man page of strace(1) makes you assume that the given numbers are not too accurate.
  • In multi-threaded scenarios, large times for certain system calls naturally need not imply delays in start up (if those delays are compensated for by other threads making progress).
  • Similarly, in multi-process scenarios, large times for certain system calls naturally need not imply delays in start up either (if those delays are compensated for by other processes making progress; this is especially true for large times given for wait-family system calls that are accumulated under the ??? file tag).

The resulting measurements do exhibit some variance, but concentrating on the top listed files (i.e., filtering out mere file descriptors and ???) across cold and warm starts does show trends:

  • Accessing the four Berkeley DB files of the extension manager is costly due to fsync system calls. Typical numbers are for example 
"/sb-tree2/ooo-sb107/.openoffice.org/3/user/uno_packages/cache/registry/com.sun.star.comp.deployment.configuration.PackageRegistryBackend/registered_packages.db": 167833mu

"/sb-tree2/ooo-sb107/.openoffice.org/3/user/uno_packages/cache/uno_packages.db": 41407mu
  • Accessing images_tango.zip is costly due to many small read system calls. Typical numbers are for example 
"/sb-tree1/ooo-sb107/openoffice.org3/program/../basis-link/share/config/images_tango.zip": 119944mu

for cold start and 

"/sb-tree1/ooo-sb107/openoffice.org3/program/../basis-link/share/config/images_tango.zip": 18541mu

for warm start.

  • Accessing the directories of the OOo installation is costyl due to many repeated stat-family system calls. Typical numbers are for example 
"/sb-tree1": 21751mu
"/sb-tree1/ooo-sb107": 18782mu
"/sb-tree1/ooo-sb107/openoffice.org3": 9481mu

"/sb-tree1/ooo-sb107/openoffice.org3": 9811mu

Just after system start up run 

$ cd /sb-tree3 && valgrind --tool=callgrind --compress-strings=no /sb-tree1f/ooo-sb107/openoffice3/program/soffice.bin -swriter # press Ctrl-Q as soon as the text cursor starts to blink
$ cd /sb-tree3 && valgrind --tool=callgrind --compress-strings=no /sb-tree1f/ooo-sb107/openoffice3/program/soffice.bin -swriter # press Ctrl-Q as soon as the text cursor starts to blink
$ cd /sb-tree3 && valgrind --tool=callgrind --compress-strings=no /sb-tree1f/ooo-sb107/openoffice3/program/soffice.bin -swriter # press Ctrl-Q as soon as the text cursor starts to blink

to get one cold and two warm start-up (plus shut-down) measurements. The variance, even across cold and warm start ups, appears to be minimal.

Interesting first results, using grouping by ELF object in kcachegrind, are the instruction reads spent directly within the top scoring ELF objects:

Symbolic Linking

Issue 85679 “Link with -Wl,-Bsymbolic-functions -Wl,--dynamic-list-cpp-new -Wl,--dynamic-list-cpp-typeinfo when supported” suggest a performance boost on Linux through symbolic linking. This requires a fairly recent GNU ld. Experimenting with combining the existing (GCC 3.4.1 based) Hamburg unxlngi6.pro tool chain with (latest, as of March 2009) ld 2.19.1 failed, so I set up an environment using GNU binutils 2.19.1 and GNU GCC 4.3.3 (again, latest as of March 2009) on v20z-so3 (see above).

  • Build the new tool chain with ~/newgcc.sh ~/newgcc && rm -rf build, where ~/newgcc.sh is 
#!/bin/bash
set -e
 
mkdir ${1?}
mkdir build
cd build
 
wget http://ftp.gnu.org/gnu/binutils/binutils-2.19.1.tar.bz2
tar xfj binutils-2.19.1.tar.bz2
mkdir binutils-build
(cd binutils-build; \
 ../binutils-2.19.1/configure --prefix=${1?}; \
 make; make install)
 
wget http://ftp.gnu.org/gnu/gmp/gmp-4.2.4.tar.bz2
tar xfj gmp-4.2.4.tar.bz2
 
wget http://www.mpfr.org/mpfr-2.4.1/mpfr-2.4.1.tar.bz2
tar xfj mpfr-2.4.1.tar.bz2
wget http://www.mpfr.org/mpfr-2.4.1/patches
(cd mpfr-2.4.1; patch -N -Z -p1 < ../patches)
 
wget http://ftp.gnu.org/gnu/gcc/gcc-4.3.3/gcc-4.3.3.tar.bz2
tar xfj gcc-4.3.3.tar.bz2
ln -s ../gmp-4.2.4 gcc-4.3.3/gmp
ln -s ../mpfr-2.4.1 gcc-4.3.3/mpfr
mkdir gcc-build
(cd gcc-build; \
 export PATH=${1?}${PATH+:$PATH}; \
 ../gcc-4.3.3/configure --prefix=${1?} --enable-languages=c,c++; \
 make; make install)
  • Again using CWS sb107 (see above), by now based on DEV300m42, replace the (Hamburg-internal) compiler-support libraries at $SRC_ROOT/so_prereq/baseline/unxlngi6 (libgcc_s.so.1, libstdc++.a, libstdc++.la, libstdc++.so.6.0.1) with the ones from the new tool chain (libgcc_s.so.1, libstdc++.a, libstdc++.la, libstdc++.so.6.0.10) and in $SRC_ROOT/solenv/bin/rpm-wrapper replace “${COMPATH?}” with “/so/env/gcc_3.4.1_p_linux_libc2.24”.
  • Merge in the relevant changes from Issue 85679 to support HAVE_LD_BSYMBOLIC_FUNCTIONS (ignoring the configure changes that are not relevant for a setsolar environment): 
cd $SOURCE_ROOT/DEV300/ooo && svn merge --ignore-ancestry svn://svn.services.openoffice.org/ooo/cws/buildporting31b -r 264159:264162
  • Remove “SO:b_server” from $SRC_ROOT/top/prj/build.lst, to avoid an error later on when building (irrelevant, for OOo installation sets) $SRC_ROOT/soldep/bootstrp.
  • Unfortunately, I did not manage to combine the standard Hamburg build environment (setting a specific sysbaseroot) with the new toolchain, so had to go with a null sysbaseroot (i.e., using stuff directly from the v20z-so3 build machine). This means that results might be slightly different between the vanilla reference build and the builds checking the effects of symbolic linking.
  • I did three builds:
    • Build N using just the new tool chain (EXTERNAL_WARNINGS_NOT_ERRORS=TRUE is necessary as OOo is not yet completely warning-free for GCC 4.3.3): 
SYSBASE_ROOT= setcws -pro sb107 -- -compath ~/newgcc -sysbaseroot
cd $SRC_ROOT/finalize && EXTERNAL_WARNINGS_NOT_ERRORS=TRUE build --all
    • Build S actually enabling symbolic linking: 
SYSBASE_ROOT= setcws -pro sb107 -- -compath ~/newgcc -sysbaseroot
cd $SRC_ROOT/finalize && EXTERNAL_WARNINGS_NOT_ERRORS=TRUE HAVE_LD_BSYMBOLIC_FUNCTIONS=TRUE build --all
    • Build&nbps;F using full symbolic linking (for functions and data) instead of symbolic linking for functions only, see issue 85679 additional comment 7. For that, I changed from “-Wl,-Bsymbolic-functions” to “-Wl,-Bsymbolic” in $SRC_ROOT/solenv/inc/unxlngi6.mk (and forgot to adapt $SRC_ROOT/icu/makefile.mk and $SRC_ROOT/stlport/makefile.mk accordingly, which, however, should only have a minor effect on the resulting numbers). 
SYSBASE_ROOT= setcws -pro sb107 -- -compath ~/newgcc -sysbaseroot
cd $SRC_ROOT/finalize && EXTERNAL_WARNINGS_NOT_ERRORS=TRUE HAVE_LD_BSYMBOLIC_FUNCTIONS=TRUE build --all

This gave me four OOo installation sets (the original O one built with the standard Hamburg build environment, and the three new N, S, and F ones), which were measured on the dedicated machine (see above).
