Hi,

thanks for your support.
I tried upgrading and switch to cfq scheduling policy, but
I noticed that the MTRR feature is not enabled anymore.
Is this correct?

My general feeling is that write-caching on the disk is disabled, so when the I/O pressure is high the impact on machine responsiveness is noticeable.

How could I check if this is the case or not? I mean, how can I measure disk I/O throughput when there are several concurrent accesses?

Also, could the overhead of vzfs be (at least partially) responsible?

As a side note, on the hardware node we are using an ext3 filesystem, and our VPSes make heavy use of LOTS of small files and LOTS of symlinks. Should we use a different filesystem to improve performance?

Thanks again!
Gerlando
