Hi All, I am experiencing some performance issues on my new OVZ setup. I have about 5 VPS created. I start to read about UBC but don't quite understand how to properly set UBC.
FYI, I have 4G available and not doing any user traffic right now. Thanks in advance for your help in fixing below!

. You have 104 + 35 = 139. They consume something like 1MB of kernel memory. There are 35 processes. They also consume 1MB of kernel memory (I have a number of 6 pages per/process as a minimum). There are other consumers like open files etc. So, the limit should be definitely higher.
