Hello!

We are investigating if it is possible to use IDEA 3.0 with new JDK. Before
that investigation we cannot say yes or no.
By the way, in your opinion what could be the benefits if IDEA 3.0 would be
bundled with the new JDK?

if you follow the normal commercial route of enticing customers to
upgrade to get the latest and greatest, IMO you should let idea 3.0 run
on the old jdk but allow to develop projects with 142 as a target, which
i believe works already.

I have said it will be for 8xx build. This is Aurora, not Ariadna.

Indeed. I think many people pay too much attention about IDEA's own runtime. If everything works ok, why should this bother the end
user?

because a good % of your users, which gets sky-high on the EAP (and tha
includes me ) is composed of hackers, who try things for the fun of it.

BTW, I have a help request for INTELLIJ in the thread "SourceSafe on
Linux" - what could be hackier ;) ?

One reason is that performance improvements are claimed with the new JRE and I guess we'd all like IDEA to run as fast as possible.

http://java.sun.com/j2se/1.4.2/1.4.2_whitepaper.html

Maybe it won't make any difference, maybe it will.

It makes no difference to me which jdk idea runs in. Since I don't know the application at the code level I would ask for jetbrains to use whichever will make the 3.0.5 the most stable.

If anyone is having serious, repeatable performance problems I would suggest creating a new thread. In the past jetbrains has always been very responsive when it comes to performance problems.

Oh, I see. I did not mean that we'll neccesary include 1.4.2 in 706.

errr...is it me, or do File Chooser dialogs take so long to become usable that my colleagues are cursing at IDEA? "its too slow.." - and they're right, its unacceptabley slow - there's no need to wait 5-10 seconds foe the file chooser contents to show up. Sun apparently fixed the filechooser in 1.4.2. can a jetbrains person comment on if this issue is really resolved in 1.4.2?

seriously, this is a major and known pain. this was discussed a while back also. i think it's worth bundling ariadna with 1.4.2 just for the speed boost.

click file open icon - 45 s
click Look in pull down list - 15 s
open my work folder in file chooser - 25 s
configure libs - add - 22 s

on xp at work for myself and colleagues.

if that is helped by 1.4.2 then please consider bundling it,

Thanks.

It might be interesting to try the new concurrent low-pause garbage
collector.
It's quite annoying when IDEA stops during 10 seconds to garbage collect !

Well, speed, maybe. But changing JDK may also affect stabulity. And any code added in order to be able to use the new JDK, may
introduce bugs, which also affects stability. Anyway, if everything is ok, we'll bundle the new JDK with Ariadna.

Perhaps something wrong with your hardware? It's first time I hear about
such HUGE performance problem with JFileChooser. It's known that file
chooser isn't very fast but 45s for open file looks like fantastic.
Probably you are opening files that are on remote computer with slow
connect. Anyway 1.4.2 will not improve file chooser dramatically. Even
4.5s (10 times faster) is already very bad for "open file" operation.

Perhaps decreasing -mx setting will help. It will make garbage collector invocations more frequent and will avoid long pauses.

I'm using concurrent low-paused GC and I don't feel any improvements.

I've put "-Xms42m -Xmx128m" (though I've got 512Mb of RAM).
It's the best parameters I've found.
The gc is not called too often.
But still, when it's called, it takes serveral seconds to do the job.
BTW, I feel that Aurora is less memory hungry compared with Ariadna,
especially with the new Optimization process.
Did you measure that too ?

Guillaume try adding this:

-XX:NewRatio=3

To me it seems to reduce the number of full GCs and produce more short
incremental GCs.

i do have network drives, but i never really go into them from IDEA. we have a very fast network at work. Thanks for considering this. i'm hoping that the bug below applies to me.

If you relax restriction (even if only for EAP build) on using other than
bundled JRE (or being able to substitute the bundled JRE with another one) I
am sure people will be happy to give it a try

I was hoping that too, but just did a simple test and was sorely dissapointed. The class below just constructs a JFileChooser, and is consistenly so much slower for 1.4 (1.4.1 and 1.4.2) it's just not funny:

<![CDATA[import javax.swing.JFileChooser;

public class FileC {
    public static void main(String args[]) {
        new JFileChooser();
        System.exit(0);
    }
}
]]>


Running it with 1.3.1 is consistenly quicker, and the only thing I can think of is it being down to that 'Look in' drop-down. Quick figures for difference are that on my file system the code above has never taken more than 5 seconds from a cold start under 1.3.1, whereas it repeatedly takes around 30 seconds under 1.4. Something somewhere is clearly still wrong.
