| |
Hello Andrea,
I gave your new vm a try and I have to report a problem. System is an Athlon 1200 with 256MB memory. Workload:
1. top refreshing every second reniced to -10 2. alsaplayer -n -q -r *.wav 3. make -j4 bzImage modules
The problem is that with 2.4.10-pre11 alsaplayer is skiping very much. Almost every ten seconds and then the break seems to be relatevily long (like >1s). With 2.4.10-pre10 I noticed alsaplayer skiping once or twice during the whole build (which takes about 6min) for a very short time (like a cd player skipping over a scratch). Here is the diff output of time -v of the make -j4 command:

Well, yeah ... I suppose there's no point in getting greedy, is there?
