Available in: 4  

History:

Changes to collapsed_forwarding_shared_entries_limit in Squid-4:

New directive to limit the size of a table used for sharing information about collapsible entries among SMP workers.

This directive is not available in the 3.5 version of Squid.

For older versions than 3.3 see the linked pages above

Configuration Details:

Option Name:collapsed_forwarding_shared_entries_limit
Replaces:
Requires:
Default Value:collapsed_forwarding_shared_entries_limit 16384
Suggested Config:

	This limits the size of a table used for sharing information
	about collapsible entries among SMP workers. Limiting sharing
	too much results in cache content duplication and missed
	collapsing opportunities. Using excessively large values
	wastes shared memory.

	The limit should be significantly larger then the number of
	concurrent collapsible entries one wants to share. For a cache
	that handles less than 5000 concurrent requests, the default
	setting of 16384 should be plenty.

	If the limit is set to zero, it disables sharing of collapsed
	forwarding between SMP workers.
