I think the IDE is really slow. Did anybody find a way to speed this thing
up?
Is there probably a JIT existing for QNX to accelerate the java stuff?

Are you passing the vm arguments to the QDE on startup, to increase the
memory used?
Which platform are you running on? There are different parameters depending
on what platform/JDT you are running.

Hi Judy,
I am running the IDE on a QNX 6.2 host. Target is also a QNX 6.2 x86
system.
Where can I find a description of the vm-argunments?
Regards
Frank

On 6.2 we are using the IBM J9 VM. You would add the following arguments to
the script that launches the binary
-vmargs -ms:20 -jit -mo:32000 -mx:200000
In the latest version 6.2.1 we are recommending the following:
In the starup script there should be a variable for vmargs. It should look
like the following and be passed to the QDE binary.
vm_args="-vmargs -nojit -Dswt.system.font=TextFont08 -ms:32 -mso:256 "
I hope this helps.

Thanks Judy,
unfortunately nothing of these combinations seam to gain any speed of the
IDE.
Maybe I am doing something wrong? To start the IDE I use:
eclipse -vmargs -ms:20 -jit -mo:32000 -mx:200000
The other cal I tried by exporting a variable vm_agrs with the described
arguments and afterwards I used
eclipse -vm_args.
I also noticed, that I can not open every file within the IDE. Sometimes
the contained functions are also not displayed in the Projects-Window
where th information about the files are displayed.

Frank

Hello Frank…
You might want to try turning off the jit. With the version of j9 we
are currently using, the jit is not always faster (ironically).
