Hello, I'm playing with 2.6 squid as an image cache/accelerator and maybe somebody can give some notes about such issues. Is there a way (prolly somebody has allready asked before) or a patch to make Squid put some objects only in memory? In case of lots (few hundred thousands) small (2-3kb) image files keeping them as copy on hdd isnt very efficient (well okay you can let also the OS cache the files in buffer still I have bad experience with the IO and swaping that way)? Actually something like minimum_disk_cache_object_size (the same as minimum_object_size but ignored for ram) setting combined with maximum_object_size_in_memory would be required.. Is there sense in making more than a one COSS cache_dir (distribute objects by size) for example: cache_dir coss /data/squid/smallfiles 10000 block-size=2048 max-size=8192 cache_dir coss /data/squid/bigerfiles 10000 block-size=2048 max-size=131072 cache_dir aufs /data/squid/var/cache 16000 16 16 with best regards Reinis
