Performance Issues


The Upsource Frontend process constantly consumes 300-600% CPU. Could you please advice whether this is a normal behavior, or what could be wrong in my configuration?

I use this Docker image:

The server where Upsource runs is an Intel Xeon 3.7 GHz with 32 GB RAM. Ubuntu 14.04, JRE 1.8.0_66-b17. The only other non-system service running on the same server is YouTrack, but it barely shows up in the top in comparison to all Upsource processes.

Not sure about the reason of such behavior. Could you please attach Upsource logs? 

Thanks in advance.

It seems the problem has resolved after I made the following two changes:

  • There is/was a bug in AUFS, so I've switched to OverlayFS. You can find more information about that in UP-5924.
  • I've doubled Xmx in all conf/*/*.jvmoptions files.

Upsource now takes even more memory, but at least it doesn't kill the CPU, and no zombie processes.

P.S. The logs were essentially empty.
