Dear Mr. Zaidi Thanks For your reply, HTTP SERVER, KDE was only selection in the installation process, my directory cache is
ufs 5500 16 256 What should be the recommended cache_mem? As I have 512MB ram in my system. Regards, Subtain -----Original Message----- From: A.Sajjad Zaidi [mailto:[EMAIL PROTECTED] On Behalf Of A.

That includes memory used by buffers and cached objects. The second row shows that you are actually only using 125712 kbytes which seems small, even if you aren't running many services. If all your RAM was used up, there would be at least some swap memory in use and the output shows 0 for that. > In such condition users get jerky and very slow response. > > I have even tried to set cache_mem 0 MB but it doesn't work. It looks like you are giving too little memory to Squid. Increase the settings until it starts using more without resorting to swap. This should make things smoother, but there are a lot of other factors to consider. Are there any other services running on the machine? What does your cache directory layout look like? How is the throughput of your drives? etc. -- A. Sajjad Zaidi GnuPG Key ID: 0xD7AD0E13 "Don't worry.. Stuart is taking an insanity break right now. Cthulhu appeared in his dreams again last night."
