Squid basics + SMP
O’Reilly has a good article covering the basics of tuning a production squid http caching server. These are things that if you have never run a production squid cluster before can be good to know as a number of them can bite you if you don’t take them into consideration.
One thing thats not covered in that article is that squid is for the most part not SMP aware. If you are going to deploy a squid server on a dual cpu box you really want to keep in mind that you may need to run two instances on different ports/ip’s to get the full capacity from your server.
