High CPU usage

Both versions 4 and 4.5 have this problem which has gotten to the point that it is not workable anymore.

After some time working on a project, Rubymine starts to use both CPU's continuously at a high level. Everything becomes sluggish, tests run forever, etc.

If you can tell me what you need, I can send you the logs.

Hope this can be fixed soon...

Please capture and upload CPU snapshot as described here (CPU snapshot capturing instructions section)

Hi Dennis,

The files are uploaded. I uploaded two of them:

  • RM-118.472_rcavandijk_23.05.2012_11.47.15.zip. Taken not too long after startup, CPU usage was high.
  • RM-118.472_rcavandijk_23.05.2012_11.53.27.zip. Taken a bit later, when the UI was at times unresponsive as well.


Hope this contains some clues for you.

Hmmm just noticed that the allocated memory, which I always increase when installing an update, is still at a low value. So it may be a case of swapping. I will increase it, and let you know what happens.

FYI, after increasing the allocations, the problem is still there...

Hi Dennis,

Were the files I ftp'ed useable? Or do you require longer snaphots?

Best regards,
Rob

After installing the patch that was released this weekend, performance for Rubymine has unfortunately become even worse. The editor hangs for ~6 seconds every 20 seconds. I uploaded a cpu usage snapshot: RM-118.533_rcavandijk_29.05.2012_17.44.51.zip.

Hope this can be resolved soon.

Hi Dennis,

High CPU usage has become worse again lately so I made a CPU snapshot and uploaded it. The name is RM-119.71_rcavandijk_20.01.2013_20.14.32.zip .

Can you please investigate it and help me solve this? It happens quite frequently lately and hinders my daily work.

Thanks and best regards,
Rob

Looks like latest Enoki EAP contains fixes for your problem. Could you please try it?

Have installed it just now, will let you know whether the problem is gone or not.

Thanks,

Had again a period of high cpu usage, after about 5 minutes. Uploaded a cpu snapshot: RM-124.524_rcavandijk_21.01.2013_09.10.14.zip

After having worked with Enoki the whole day, I wanted to let you know that it is definitely much better in terms of high CPU usage. It only occurred once, after 5 minutes - after that it worked like a charm.

That's good to hear. Most likely it was caused by initial reindexing and stubs updating. Feel free to report if it happens again.

Hi Dennis,

The Enoki version is better than the 4.x version I was using before. But periods of high cpu usage still frequently occur, and the user interface is sluggish then. They do not last as long as before, so that is good.

I uploaded a CPU profile from the last time it happened: RM-124.524_rcavandijk_23.01.2013_18.52.50.zip. Hope you find the reason why this still happens.

Regards,
Rob

Hmmmm fell into the same trap again. Did not increase memory settings yet for Enoki (Xmx etc), so the sluggishness may have been caused by swapping. Have increase the memory now, so let's see if that helps.

It would be very nice if newer versions would adopt the memory settings from the previous version. It is not the first time I forget to do this ;-)
