IntelliJ IDEA 11 RC2: It’s Getting Faster All the Time

We’ve just uploaded IntelliJ IDEA 11 Release Candidate 2 for you to try. Download it now and check the changelist if you are interested.

Also, some numbers for the curious minds.

Last year, just before version 10 release, we had made some benchmarks for IntelliJ IDEA 10 indexing speed. It was good for the size of project we had at the time. But it grows constantly, that’s why we have to return to this subject. Let’s see if IntelliJ IDEA 11 performance fits its own codebase.

Another bottleneck of developer’s productivity is application startup time. We’ve spent some efforts on this, too. Here are the results

Note that the startup time was measured at the first IDE start after switching computer power on. IDE restart time is much shorter, just about 30 seconds.

Full specs of the computers we used:
1. Windows 7: Core i7 (2.8 GHz), HDD 10K rpm, Windows 7 x64 (32-bit JRE)
2. Linux: Core i7 (2.8 GHz), HDD 10K rpm, Ubuntu 10.10 x64 (32-bit JRE)
3. Mac OS X: Mac Pro (2.8 GHz), HDD 7200 rpm, Mac OS X 10.7 Lion (64-bit JRE)

Enjoy the speed!

    Hmm… Why is Linux worse than Mac OS X? Seems strange to me.

    @harryhoppel They are not the same hardware (W/L use i7 but OSX uses Xenon), plus both windows and linux use a 32 bit VM and Mac OS X uses a 64 bit one (faster probably).

    Startup time is really not interesting. When starting once or twice a day but working for 8 hours it really doesn’t matter whether IDEA starts in 5 or 1 minute. More important is editing/compiling/analyzing times.

    So I’m guessing automatic syncing with gradle (or even much stronger gradle integration) isn’t going to make it for 11?

    @harryhoppel: it’s because of 64 bit jre I think

    I’d love to see the numbers if a SSD is used.

    @Hani: ‘sync with gradle’ is in progress, the ‘gradle’ plugin will be available for downloading as soon as that is done.

    @harryhoppel Aside x64 JDK, Mac usually lack JDK sources we are indexing on other platforms

    @Stefan I use new Mac Air with SSD to work on IntelliJ IDEA project. it’s sweet and much, much faster than ANY workstation with 7200rpm HDD.

    Why dont people just by solid state hdds?

    @Konstantin: I know SSD’s are much faster, but it would be nice to have some number comparing a HDD with a SSD for the same hardware.

    This is my way for accelerating any version of the IDEA (on linux):

    cd ~/.IdeaIC11/system/
    sudo mount -t tmpfs tmpfs caches
    sudo mount -t tmpfs tmpfs index
    sudo chown myuser:myuser caches index

    I evaluated sometime ago startup time on my project and found it is seriously impacted by gc settings. Default settings are not optimal for modern machines and ~30% of startup + opening project spent on gc. discussion thread is here
