This might be a question for freebsd-hackers, which is more developer-oriented than -questions. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

sleep is not working to avoid starvation among threads of same priority
Hi, I have two threads of same priority lets say thread A and thread B, thread A is starving since thread B has got a for loop of size 100k. So, to avoid starvation I am processing 1000 iterations of for loop(that of thread B) in one batch and giving sleep of 1ms, but still thread A is starving. If I increase the batch size used in for loop from 1k to 10k then starvation of thread A is little less whereas it should be more as Im increasing processing time of thread B. I tried various combinations of sleeps and batches, but I couldnt solve the starvation of thread A. Is the sleep right solution? I will be grateful if someone could answer on this.

sleep is not working to avoid starvation among threads of same priority
Hi, I have two threads of same priority lets say thread A and thread B, thread A is starving since thread B has got a for loop of size 100k. So, to avoid starvation I am processing 1000 iterations of for loop(that of thread B) in one batch and giving sleep of 1ms, but still thread A is starving. If I increase the batch size used in for loop from 1k to 10k then starvation of thread A is little less whereas it should be more as Im increasing processing time of thread B. I tried various combinations of sleeps and batches, but I couldnt solve the starvation of thread A. Is the sleep right solution? I will be grateful if someone could answer on this.
