I benchmarked ccache for throughput [1], memory consumption [2], and hit rate [3]. For hit rate simulations, I used golang-lru's LRU implementation, though I doubt a correct LRU implementation would show meaningful hit rate differences.

Note that otter's simulator results were repeatedly compared against both W-TinyLFU's (Caffeine) and S3-FIFO's (Libcachesim) simulators, showing nearly identical results with differences within hundredths of a percent.
