That's like asking a crystal sphere whether the woman you love is the right one to marry... How many users did use your old server? How many incoming messages per second? How much storage was used? How many clients did connect simulteanously to your old Cyrus server? > At present, we have a lot of I/O, we wonder if the last version of cyrus > is improved for this point ? We stored (before using graylisting) 30 messages/sec via Cyrus on two mirrored SAN volumes. 1200 imapd are running on peak times. No murder. 8 TB storage; 2TB used. 58,000 mailboxes; 12,000 users. 20 GB RAM, 14 GB ARC (zfs cache). SAN via Sun MPxIO (scsi_vhci). You see, without knowing the size of your old Cyrus solution it is not possible to say whether it is "enough" or not. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
