I don't know of any such patch, and I think there are other areas being
more important to work on from a performance point of view.

However, there have been some research in cache replacement algorithms
which indicates that having a memory based hot items cache may be
beneficial if a better replacement algorithm is used than Squids
modified LRU. So given gobs of memory (equivalent of some minutes worth
of traffic at least) and a suitable replacement algorithm then there may
be true benefit in having a hot-object cache for small objects.
