Squid estimates how many store buckets to use based on your 'cache_swap'
setting. It asssumes that the average object size is 20k. If you
decrease 'store_objects_per_bucket' then you increase the total number
of buckets, and therefore the rate at which buckets are "cleaned out."

But I don't think that is your problem. You may want to try building
squid with GNU libmalloc. Brian Denehy <> reported
a significant performance improvement on DEC Alpha when using GNU malloc.
