This looks like the same problem I am having with Star Wars: KotOR I and II. 
For Knights I, it starts going slow right after inserting disc 3 and continues
slow with disc 4 (both have wav files).  Total wine install is about 16 hrs. 
Probably a 15 min install on a Windows box.

Knights II, the problem starts on disc 4.

Again, CPU goes 100% installing these files.  Interesting, though, the CD is
spinning so very hard for each file.  Almost like it's searching the entire disc
for the file.

I have tried this on 0.9.21 and .22.
