<div> </div>
<div><SPAN style="font-size:10pt;">I just install another distributor linux: Red hat Enterprise Advance server 4, and got better result. The same server can handle about 400 sessions, (my first test was runing on CentOS 5)</SPAN></div>
<div><SPAN style="font-size:10pt;">Yes Mike is right, SMP does not help to handle more session than single CPU server. <br /><br /></span></div>
<div><SPAN style="font-size:10pt;">Cheers</SPAN></div>
