Hi, I dont' know if this topic has been discussed previously. I was wondering how good/bad is the new value for timeslices HZ=512 for RH8.0 (other distributions?) and HZ=1000 for kernel2.5. I understand how good it is for desktop responsiveness but won't it be bad if two 'intensive' jobs are running causing a lot of cache misses at every timeslice, causing delay to refresh the cache, etc...? I'd say it'd be better for HPC to keep HZ=100 at least on x86 (1024 on alpha afaik but bigger cache). Comments? Remarks? Suggestions? Thanks JC
