Dedicated server lag spikes (virtual machines)

As you might know, YO dedicated server and MMO servers reuse some common code and of corse, bugs existed in MMO can appear on YO servers. During MMO CBT wave#3 test we were able to find one issue linked with virtual machine setup which causes huge lag spikes (2k ping +) on an almost empty server. Please check instruction in this article about virtual machine setup which resolved this issue in MMOand adopt them for your YO server if you run them in a virtual environment.

You can skip 'fallback'. Set CPU cores quantity based on a physical CPU cores

<timer name='rtc' tickpolicy='catchup'/>

<timer name='pit' tickpolicy='delay'/>

<timer name='hpet' present='no'/>

'Clock' setup configuration is still discussed, but this setup resolved our issue
