Hi All, As I known FS usually use two thread to handle one call, one  for inbound and one for outbound.  In 32bits system, a process&#39;s memory is limited to 2GB,  So I think a FS process can create  up to 500 threads, and  handle 250 call in the same time. Is it right? How if FS run in 64bits system?  <br clear="all">
