Rumour goes that > 2.4 supports 16384 processes, so poster should try a 2.3.99pre<x> kernel. Vanilla Linux 2.2.x supports 512 processes, defined by NR_TASKS. 4090 is a hardware limit that can't be passed in 2.2.x Linux 2.4.x will support an unlimited number of processes up to the point of 256^sizeof(pid_t). Most people will probably run out of RAM before they hit this limit. Poster should screw benchmarks out of fear of holy war. :) -MB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
