Sorry, I do not understand this one: >This is the reason we still say diskd is fastest on BSD but AUFS is >faster on Linux. I compiled squid27 on LINUX (SuSE), and because of #define ASYNC_WRITE 0 then diskd should also be faster here. Unless the performance gain on async READs using AUFS overcompensates async READ/WRITE gains using ufs/diskd. -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/squid-2-7-AUFS-Only-READS-are-async-tp4405056p4405310.html Sent from the Squid - Users mailing list archive at Nabble.com.
