Another thing of note is that this sort of problem will only happen (or rather, will only be severe) when the server goes instantaneously from x concurrent connections on average to x+y concurrent connections, where y is large, which is what's happening when you suddenly ab pound a server, because p_i_s_m doesn't have a chance to keep up. Under production circumstances, the number of concurrent connections would tend to have less significant discontinuities. --Cliff -------------------------------------------------------------- Cliff Woolley [EMAIL PROTECTED] Charlottesville, VA
