In Cyrus IMAP there is a issue with message writing to IMAP folders. Reading of 8MB message takes a bit less than a second, but in that time 8MB message write to IMAP folder over 100Mbit/s connection takes ~7 seconds. If writing many small messages to imap folder (~1KB in size) then average transfer rate of them is ~10 messages per second. Hardware: (2x 3GHx Xeon, 2GB RAM, Adaptec 2410SA, 2x WD RAPTOR 74GB, 2x SEAGATE 300GB, Mainboard - Intel SE7520BD2) For example, there is no such problems with FTP. >How-To-Repeat: >Fix: "sysctl -w net.inet.tcp.delayed_ack=0" fixes mentioned problems with data transfer >Release-Note: >Audit-Trail: >Unformatted:
