Hi, I'm using Windows 2000 Server. I don't know if I have pushed my server very hard because there is no warning event on server resource monitoring system. I have done with this trouble and have almost sophisticated result by doing following configuration. * give diffrent IP and port for each Squid instance by http_port * give diffrent port for each Squid instance by icp_port * give diffrent IP for each Squid instance by tcp_outgoing_address (for handling different ISP) * give diffrent IP for each Squid instance by udp_incoming_address Main Squid -(Parent)-> Parent Squid A -(Direct)-> ISP A Main Squid -(Parent)-> Parent Squid B -(Direct)-> ISP B Parent Squid A <-(Sibling)-> Parent Squid B Best regards, -----Original Message----- From: Guido Serassio [mailto:guido.serassio@xxxxxxxxxxxxxxxxx] Sent: Thursday, March 06, 2008 5:22 AM To: Lazuardi Nasution; squid-users@xxxxxxxxxxxxxxx Subject: RE: Multi ISP Load Balancing Problem HI, At 19:58 04/03/2008, Lazuardi Nasution wrote: >Hi, > >I'm using Windows 2000 with Service Pack 4.

I think that you are pushing too much squid under Windows. >But the performance with 3 Squid Services still bad. select() is the worst Squid comm loops. For a really high performance cache, you should use another OS.
