| |
Dear List(s),
as part of my project I need to run a very high number of processes/threads on a linux machine. Right now I have a Dual-PIII 1.4G w/ 8GB RAM -- I am running 4000 processes w/ 2-3 threads each totaling in a process count of 15000+ processes (since Linux doesn't really distinguish between threads and processes...). Once I pass the 10000 (+/-) pocesses load increases drastically (on startup, although it returns to normal), however the system time (on one processor) reaches for 54% (12061 procs) while the only non sleeping process is top -- the system is basically doing nothing (except scheduling the "nothing" which consumes significant system time). Is there anything I can do to reduce that system load/time? (I haven't been able to exactly define the "line" but it definitly gets worse the more processes need to be handled.) Does any of the patchsets address this particular problem? BTW: The processes are all alike...
Thanks for you help!
Immanuel
