Figure 1
Sorry for this rather boring listing. It's based on an spreadsheet analysis of an Xcache Administration report of our live VirtualBox forum. This puts each compiled module into a multiple of 8K blocks. In general the numbers of byte-codes executed is correlated to the compiled code size so the total number of lines correlates to bytes-codes x number of hits. You can see a classic Pareto distribution in play here. 8Mb is enough to cache 99.5% of all hits and a 24Mb cache will entirely cache the phpBB code base, though the LRU flushing of the cache will be minimal with 16Mb.
