[Bug 217580] Re: Slow performance with Gmail

[stek79]

I've profiled the system while executing the previously described
workload.

Attached you can find oprofile output.

Even though there are no symbols (I guess I need debug packages for that),
it shows where the time is spent.

Alex, let me know if symbols might be interesting to track this down.
