Hi Michael and Brian, Thanks for your answers. <br>Brian, Did you mean set the thread stack size to 240KB? Is it enough for FS?  If thread stack size is 240kB, so FS can create about 4000 threads and handle 2000  concurrent call?<br>

Is it right? How if FS run in 64bits system? <span> </span><br clear="all">
