In addition to his question, brian.. Is it possible before a system shutdown squid will save all cache objects from RAM to disks? And load all cache object from object to RAM? coz you have /dev/null as the cache directory...

To extract the most out of this box, try * Squid ufs over Linux tmpfs or the null fs and large cache_mem & maximum_object_size_in_memory * If this uses an Intel NIC, replace it with a 3com * A kernel update -- the 2.4 jam patches are very nice. > Due to growing load - 400 hits/sec, we are experincing loads about > 30% user and 65% system-time > > Is this alarming? Should we consider bying "web"-switches and adding > furter servers? The system time seems a bit high for a squid server that should be 100% in memory. The NIC and the filesystem are the likely culprits. At 400 req/sec, I would consider a trio of servers just for smoothing over uprades or other downtime. Obviously the budget is not always so flexible. > As the site is quite small, would it be a good idea to build a > "mini"-linux booting of floppy/CD with no harddrives/filesystems? Not really necessary -- with that much RAM, yous shouldn't be touching the hard drive, anyway. I would go with null storage or tmpfs for the squid cache, though. -- Brian -- This message has been scanned for viruses and dangerous contents on SSCR Email Scanner Server, and is believed to be clean. --- Incoming mail is certified Virus Free.
