Hi Satya, By todays standards, 25% byte hit ratio is pretty good. Very good rates usually top out at about 30-35% and many sites only get around 15%. Hit ratios are really dependant on what sites your users are using.
If you have many users accessing the same few web sites day in day out, you will see higher hit rates. The bandwidth you have to your site dose not really have any effect on your hit rations. Many of us these days run a cache for improved web performance with web hits as a secondary priority. As Squid is so reliable, runs on minimal hardware and has virtually no management overhead, even getting a 10% hit rate make it worthwhile. At my site we are getting about 20% and we are happy with that. We have a 7 gig cache and we have have about 10 gig a month in http traffic. But if we configure our browsers to bypass Squid, users do notice and they do complain! >From a config point of view though, GDSF achieves the highest object hit ratio, not byte hit ratio. To achieve higher byte hit ratio you could try using either LFUDA or LRU. For my users I find the original LRU works best.
