EventStore idle activity on Linux

Hello,
I’ve attached a screenshot of EventStore Charts admin page which shows the state of an idle EventStore instance after a couple of hours of operation.
As you can see, all of the disk operations are slowly increasing (disk written bytes ~5mb/hour) and I’m not sure whether this is a glitch in the admin page or the normal operation of EventStore. If it’s the latter - what is it doing?

This is the first time I’ve even tried to run something with mono, so this may be a known issue, but the CPU usage never falls below 10%. Is this normal?

I’m running an up to date Debian 6/testing.

Statistics gathering writes to the log by default (unless you change nlog config) this is my guess what’s causing it.

For CPU usage I have seen this as well with mono (on my machine it’s 4% though)
