Re: Trying to understand why LO seems freezed for some seconds when a module is started
It would be interesting to know if Dezsi personal build with the fix about slow loading replacement table has still the issue I'm describing here... maybe, if we are lucky, that fix could somehow have influence even on the freeze I'm describing. we were lucky!!!

Re: Trying to understand why LO seems freezed for some seconds when a module is started
Tommy, I still got a small freeze (1 or 2 seconds) on master (see my comment https://bugs.freedesktop.org/show_bug.cgi?id=46765#c7) but the improvement is huge ! (forgot to tell on the bugtracker comment I had removed my LO profile for the test).

Le 28/02/12 11:56, Michael Meeks a écrit : Hi all, It'd be great to get a bug opened to collect the detailed information on this. Clearly we don't want such delays when you start typing. Just to add my 2c worth, I can also confirm that this happens on Mac too, and always on first data entry, i.e. when the keys to type something in are first pressed, be it a document, a filename entry, renaming in a dialog, etc. On Mac, you get a nice spinning beachball for a couple of seconds, then LO suddenly springs to life and enters the characters that have been typed in (or at least those that made it into the buffer).

Re: Trying to understand why LO seems freezed for some seconds when a module is started
Hi Tommy, I read your post but I can answer only rarely from my day work + there were no questions (or perhaps I missed it :-) ) I'm compiling right now master sources because I reproduced this freeze on master too. I also must recompile from scratch 3.5 because I don't know if lightproof is used or not. I had lightproof on my autogen.lastrun, then I removed it but didn't recompile from scratch, so perhaps it wasn't sufficient like I said in a previous post. So as soon as it'll be finished, I'll add comment on the bugtracker.

I'd personally do that twice - once with some continues, so press ctrl-c five time once per second for the 5 seconds [ basically dumb sampling profiling ], and log the stack traces (with symbols).

I noticed these lines too :
700 #ifdef MACOSX
701 vm_args.version= JNI_VERSION_1_4; // issue 88987
702 #else
703 vm_args.version= JNI_VERSION_1_2;
704 #endif
If we support jdk 1.4 min, we could use JNI version 1.4 according to this
http://docs.oracle.com/javase/1.4.2/docs/guide/jni/jni-14.html, no ? (or
perhaps it would need lots of changes to use it except for MacOS where it's
already used)
Yes, we could probably simplify the code by always using
JNI_VERSION_1_4. But it should probably not make a difference (note
that the example at
http://docs.oracle.com/javase/7/docs/technotes/guides/jni/spec/invocation.html#wp16334
still uses 1_2, and only states that it must be at least 1_2, but not
that setting it to a higher value has any special effect), and who knows
what would break with all those varied JVM implementations out there.

That sounds -very- much like the java grammar checker - LanguageTool. This behaviour is entirely expected - we defer the horrible first-start performance penalty of the JVM until the very last minute, but as you start to type ... Bang ! ;-) and yes, I've seen this on at least three users' laptops they brought to me saying OO.o performance sucks and simply removing the Java grammar checker removed the eight to ten second hang that occurs in each module when you start interacting ;-) Not having that is one of the big wins of the new LightProof checker ... Of course; quite why we're activating any Java stuff when you start typing in master, I don't know - you're sure it's not sharing some Java extension installed in ~ ? I guess running under gdb, hitting ctrl-c in the hang, winding the stack-trace back to see what is activating that stuff would help get us closer to the pain.

Trying to understand why LO seems freezed for some seconds when a module is started
Hello, On master branch (not on 3.5 branch), each time I start a module Calc, Writer or Impress (I didn't test on others), when I begin to type something, it seems to freeze for some seconds (about 10 secs) then everything seems ok. So I runned valgrind by using this : valgrind --tool=memcheck --num-callers=50 --trace-children=yes ./soffice.bin 21 | tee /tmp/valgrind.log With this, I can't start LO at all because there are too much errors. By taking a look, 98% of them are like this : ==4110== Invalid write of size 4 ==4110==at 0x2E7BE641: ??? ==4110==by 0x2E7AF437: ??? ==4110==by 0x2DA518CE: JavaCalls::call_helper(JavaValue*, methodHandle*, JavaCallArguments*, Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA50D04: JavaCalls::call(JavaValue*, methodHandle, JavaCallArguments*, Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA1EBC9: instanceKlass::call_class_initializer_impl(instanceKlassHandle, Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA1EC04: instanceKlass::call_class_initializer(Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA1ED96: instanceKlass::initialize_impl(instanceKlassHandle, Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA1F218: instanceKlass::initialize(Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA1F062: instanceKlass::initialize_impl(instanceKlassHandle, Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA1F218: instanceKlass::initialize(Thread*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DCEB655: Threads::create_vm(JavaVMInitArgs*, bool*) (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2DA6F920: JNI_CreateJavaVM (in /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/server/libjvm.so) ==4110==by 0x2D376369: jfw_plugin_startJavaVirtualMachine (sunjavaplugin.cxx:725) ==4110==by 0xC934F16: jfw_startVM (framework.cxx:404) ==4110==by 0x2D139F7E: stoc_javavm::JavaVirtualMachine::getJavaVM(com::sun::star::uno::Sequencesigned char const) (javavm.cxx:786) ==4110==by 0x2CF19F24: stoc_javaloader::JavaComponentLoader::getJavaLoader() (javaloader.cxx:179) ==4110==by 0x2CF1B6C8: stoc_javaloader::JavaComponentLoader::activate(rtl::OUString const, rtl::OUString const, rtl::OUString const, com::sun::star::uno::Referencecom::sun::star::registry::XRegistryKey const) (javaloader.cxx:378) ==4110==by 0x6AC06B2: cppu::ORegistryFactoryHelper::createModuleFactory() (factory.cxx:886) ==4110==by 0x6ABFA0F: cppu::ORegistryFactoryHelper::createInstanceEveryTime(com::sun::star::uno::Referencecom::sun::star::uno::XComponentContext const) (factory.cxx:736) ==4110==by 0x6ABE5B0: cppu::OSingleFactoryHelper::createInstanceWithContext(com::sun::star::uno::Referencecom::sun::star::uno::XComponentContext const) (factory.cxx:213) ==4110==by 0x6ABEF3C: cppu::OFactoryComponentHelper::createInstanceWithContext(com::sun::star::uno::Referencecom::sun::star::uno::XComponentContext const) (factory.cxx:489) ==4110==by 0x1150FF70: stoc_smgr::OServiceManager::createInstanceWithContext(rtl::OUString const, com::sun::star::uno::Referencecom::sun::star::uno::XComponentContext const) (servicemanager.cxx:1191) ==4110==by 0x115106E2: stoc_smgr::OServiceManager::createInstance(rtl::OUString const) (servicemanager.cxx:1301) ==4110==by 0x20EF8E72: framework::DispatchProvider::implts_searchProtocolHandler(com::sun::star::util::URL const) (dispatchprovider.cxx:546) ==4110==by 0x20EF856F: framework::DispatchProvider::implts_queryFrameDispatch(com::sun::star::uno::Referencecom::sun::star::frame::XFrame, com::sun::star::util::URL const, rtl::OUString const, int) (dispatchprovider.cxx:449) ==4110==by 0x20EF6B7B: framework::DispatchProvider::queryDispatch(com::sun::star::util::URL const, rtl::OUString const, int) (dispatchprovider.cxx:149) ==4110==by 0x2578FCF9: SwXDispatchProviderInterceptor::queryDispatch(com::sun::star::util::URL const, rtl::OUString const, int) (unodispatch.cxx:98) ==4110==by 0x20EFA975: framework::InterceptionHelper::queryDispatch(com::sun::star::util::URL const, rtl::OUString const, int) (interceptionhelper.cxx:129) ==4110==by 0x20FC546A: framework::Frame::queryDispatch(com::sun::star::util::URL const, rtl::OUString const, int) (frame.cxx:2068) ==4110==by 0x85A2038: svt::ToolboxController::bindListener() (toolboxcontroller.cxx:567) ==4110==by 0x85A0797: svt::ToolboxController::update() (toolboxcontroller.cxx:270) ==4110==by 0x2103AC80: framework::AddonsToolBarManager::FillToolbar(com::sun::star::uno::Sequencecom::sun::star::uno::Sequencelt;com::sun::star::beans::PropertyValue const)
