Weird SWA lags (.2096)

We have a rather large VS2010 solution (~ 150 projects, 4k files to analyse)

I used several nightly builds of resharper to refactor it. And spent a lot of time looking how resharper's doing it's work analysing stuff.
Until build 2096 it was getting through all 4k files with more or less stable speed.
What i see now - it that it goes through ~ 10-20 files then stops and waits for something for about a minute. Then continues..
Once it actually was frozen - i had to restart VS and when i did resharper restarted the whole process from scratch..

No exceptions during the process.

Another weird thing i noticed is that for some reason Resharper caches point to project folder instead of system temp and i dont remember setting tham back to it. (don't have time just now to check wether installing new version reset the option for me)
That might be a "human error" though :)

PS. after about 15 mins its analysing file 270 of 4081

Thank you for the feedback.  We've found few performance problems in latest build, and working hard to fix it. It would be great if you could send us a note if the performance problems will occur at your side after we fix them....

Hello Sergei,

Could you please take a performance snapshot of the period when SWA lags
for a minute (following the instructions at http://confluence.jetbrains.net/display/ReSharper/ReSharperPerformanceProfiling+Instructions)
and upload it to ftp://ftp.intellij.net/.uploads/, so that we could take
a closer look? As to storing the caches in solution folder, could you please
change this option back to temp folder (under ReSharper | Options | General)
and monitor the actions that might change it. Thank you!

Done.

Could you please post issue id so that i can track it and in the mean time revert to older EAP builds?

I too am seeing very anolying lags with 13.1.5 build 135.1289
When this happens, the CPU hits ~100% for anywhere between 5 and 20 seconds.  Very annoying.
I have attemped:
1. flush cache and restart.
2. increased cache:
-Xmx2048m
-XX:MaxPermSize=1024m
3. removed some unused plugins.  - but not sure which ones if any causing issue.
No improvement.
When lags appear, Java is consumming huge CPU.
Is there anyway to determine where the issue is comming from?

This is 64bit Ubuntu 14.04 - 16Gb, SSD for everything but /home
Then nicely during Help->About -> the app froze and I had to kill Java.

I have hesitated to shift to 139.1 because of these issues.
Should I attempt to shift to 139.1 or are there other issues?

Thanks for an otherwise great product.
Joel Parke
