  8.9. What can I do to reduce Squid's memory usage?

  If your cache performance is suffering because of memory limitations,
  you might consider buying more memory. But if that is not an option,
  There are a number of things to try:

  o Try a ``different malloc library''.

  o Reduce the cache_mem parameter in the config file. This controls
     how many ``hot'' objects are kept in memory. Reducing this
     parameter will not significantly affect performance, but you may
     recieve some warnings in cache.log if your cache is busy.

  o Turn the memory_pools off in the config file. This causes Squid to
     give up unused memory by calling free() instead of holding on to
     the chunk for potential, future use.

  o Reduce the cache_swap parameter in your config file. This will
     reduce the number of objects Squid keeps. Your overall hit ratio
     may go down a little, but your cache will perform significantly

  o Reduce the maximum_object_size parameter (Squid-1.1 only). You
     won't be able to cache the larger objects, and your byte volume hit
     ratio may go down, but Squid will perform better overall.
