Also, ab is quite lame... Maybe we could use a epoll based 'stresser' On my machines (again ...), ab is the slow thing... not the 'server' Some small differences in behavior could have a big impact on ab (and you could think there is a problem on the remote side) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
