It's hard to grab top info as the interface freezes up. I'd have to ssh
in from another system.

However, browsing lkml, I noticed someone saying I/O throughput was
affected by a readahead setting of 256 instead of 512 using hdparm -a
###. I changed the readahead on my root and home drives and galciv was
able to load (with some mild stuttering in the movies).

I've never adjusted this setting before. Perhaps it compensates for
scheduler activity by allowing the system to draw more data within a
given timeslice? Or am I babbling?

Running top while glaciv + wine is running with the new hdparm -a 512
setting, I can mention the following patterns:

When loading up playing AVIs, the top are wineserver, wine, wine, and X
(there is also another wine process). When the game chugs/pauses badly
in playing an avi, wineserver leaps to the top with >50% CPU with
wineserver+wine processes+x taking 100% CPU. Then when chugging lapses,
wineserver drops down to the 26% range and the other wine processes are
the same or a bit above. When the game is loaded, two wine processes at
21% CPU each are at top, then X with 5-10% then wineserver with 2-3% (a
huge drop) or even a couple of appas above wineserver.

Perhaps this data helps?
