Thanks for all the discussion, I'd like to have this thread back to it's original meaning. I made my test again today, as there's nothing else running, seems everybody else has holidays, just me stupid hacking around. I make an imapsync to my mailserver, which connects to the PostgreSQL db, and I get these numbers: mailsrv -> db 15.482.309 db -> mailsrv 648.119.851 client -> mailsrv 1.771.458 mailsrv -> client 15.956.176 So with ~18MB IMAP traffic I produce ~663MB database traffic? Can somebody explain me this? mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0676/846 914 666 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: EA39 8918 EDFF 0A68 ACFB 11B7 BA2D 060F 1C6F E6B0 // Keyserver: www.keyserver.net Key-ID: 1C6FE6B0
