No. Ufs-based store modules, including aufs, are currently not SMP-aware. If you use them in SMP Squid (without protecting them with SMP conditionals), your cache will get corrupted. SMP conditionals in squid.conf can be used to prevent corruption, but they also prevent sharing of cache_dirs among workers. Rock store and memory cache are SMP-aware, share cache among workers, and do not need SMP macros, but they have their own limitations (we are actively working on addressing most of them). Pick your poison, Alex.
