Random 30s hangs with YouTrack 4.1.1

I'm having random 30s hangs after upgrade to 4.1.1 from 3.x on my YouTrack server w/ dual core processor & 16GB RAM. Below is the statistics screen. I guess there is something wrong with my server configuration after 4.x upgrade:

Hello, Teoman.

Available memory    455.1 MB

Can you increase -Xmx up to 1gb?

Hi Vadim, how can I increase Xmx for YouTrack on Windows? As far as I can see, YouTrack has its own Tomcat/JVM bundled in the installation directory so which config file should I edit?

Thanks for the help btw.

Right to the point. Thanks a bunch. 1400MB Xmx did the trick.
