Hello, Previously, caching was disabled on our proxy servers. Now we need to cache some content (files about 10 MB in size). So we changed the squid.conf:
#Disable caching #cache deny all #no_cache deny all #cache_mem 0 cache_dir ufs /data/squid/cache 32000 16 256 max-size=12000000 We have 24 workers on each proxy. We saw that some requests were taken from the cache, and some were not. The documentation says: "In SMP configurations, cache_dir must not precede the workers option and should use configuration macros or conditionals to give each worker interested in disk caching a dedicated cache directory." I found Amos' comment that "rock cache type *is* SMP-aware" ( http://lists.squid-cache.org/pipermail/squid-users/2018-October/019410.html) So we switched to a rock cache_dir: cache_dir rock /data/squid/cache 32000 max-size=12000000 Now everything seems to be working fine in the test environment, but I found limitations on the RockStore ( https://wiki.squid-cache.org/Features/RockStore): "Objects larger than 32,000 bytes cannot be cached when cache_dirs are shared among workers." Does this mean that RockStore is not suitable for caching large files? Should I switch back to the UFS and configure 24 cache_dirs (this will lead to a significant consumption of disk space)? Kind regards, Ankor
