I tried as suggested and moved ~/.wine into an ext2 drive which I mounted with
noatime,nodiratime. No change.

I wrote a perl script to take latency and bandwidth usage stats, and used
openoffice to show them in the same graph. Here, a very simplified picture:

The IP address there is one of the lotro servers the game connects to.
Upstream usage was measured simply by reading from /proc, and latencies by the
ping command.

Here's the full speadsheet with raw data:

This clearly shows that:
- Lotro generates a lot of traffic for a moment (5 Mbit for a moment)
- The traffic amount affects latency to lotro server

Here's a full bzipped traffic capture of everything being sent and received:

You can open it with wireshark for analyzation. I've changed my account
password after the dump, so please don't waste your time trying to crack it.
;-)
Also at the end of capture I downloaded with full downstream from ftp.funet.fi
just to test how it looks in the statistics, you can just ignore it.

Here's the perl script I used to create the statistics:
