Hi Antony,
Thanks for the reply. I have made changes in squid.conf as per your
suggestion and have allocated 20 GB of Hard disk space.
Squid server at my location handles http/https requests for more than 500
hosts. But at peak hours squid usually performs very slow and browser takes
1-2 minutes just to serve google home page and more time than that for
heavy web page.
I have verified network link utilization & found it consumes not more than
15 mb whereas link bandwidth is of 45mb but still squid serves web pages
very slow to client hosts.
Any suggestions in squid configuration to overcome this issue would be
highly appreciated.
Thanks,
Krishna.
