Its just that i wonder why the Request Disk Hit Ratios are high and there is nothing in the Request Memory Hit Ratio (0% for both 5 mins and 60 mins)?

I configured my Mmemory Usage in the squid index as follows:


Memory Usage Limit - 128MB (Total physical memory is 512MB)

Disk High & Low Water Marks at 100% and 80%

Maximum cached object size - 1024Kb

My cache directory is 35GB.

what do u think?

Will expect ur comments pls.

Thanks

I guess you shouldn't temper with the default Memory usage TAGS.
Just set it back to what it was before you changed and see.
