cache_mem determines the size of in-RAM object cache. As your

Years ago I read something about how memory cache performance
degraded
progressively with increasing object size, and that increasing
maximum_object_size_in_memory substantially could actually degrade
performance. Has this been fixed in both 3.x and 2.x?
Individual object size problems is not a limit on total RAM size used
by Squid or its memory cache. You can allocate many GB of RAM cache then
only store a few million <1KB objects in it.
Most of the the large object (up to 2GB) problems were solved in 3.0.
The remainder (>2GB objects) were solved in 3.1.15.
