IMAP: Partial list fetches all messages in one go instead of batches of 100s
Hi, every time you connect your IMAP account to the server, the client synchronizes the local cache with the server. In practice, you can see in the Connection Centre that for every folder you get something like: Partial list [folder] (1-n) (0/n) where n is the number of messages in the folder. This means the The Bat! tries to sync the entire cache in one go. This is not necessarily good because for folders with tens of thousands of messages it may take considerable amount of time. The funny thing is that I remember that it used to work in a different way: in the past The Bat! would do it in batches of 100s, so you'd get something like: Partial list [folder] (1-100) (0/n) Partial list [folder] (101-200) (0/n) Partial list [folder] (201-300) (0/n) ... or, since I have trouble recalling which column means what: Partial list [folder] (1-n) (0/99) Partial list [folder] (1-n) (100/199) Partial list [folder] (1-n) (200/399) ... The important thing here is that when TB! operates in smaller batches you see the new messages in a folder much earlier than in the full sync in one go case. I am on 4.0.38 now. I am also quite sure the change happened some time in the past (maybe even when I was on last versions of 3.x). And, in the meantime I also upgraded the IMAP server I'm using (Dovecot) so I am not even sure what caused this change in behavior.

Any comments? Some clients are faster than TB starting up. Thunderbird is one. The difference with Thunderbird and most other clients is TB gets message counts for all folders in the process. The bottleneck for me with TB is negotiating the tls connection. After than, TB zips through my 100 folders and 14,000 stored messages zoomily. Much faster since I moved to a wider broadband connection. -- Gleason Current beta is 4.1.9.1 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html

Hello Gleason, Sunday, January 11, 2009, 2:03:40 PM, you wrote: Some clients are faster than TB starting up. Thunderbird is one.

After than, TB zips through my 100 folders and 14,000 stored messages zoomily. Much faster since I moved to a wider broadband connection. This is completely different than my experience with TB!. While the startup is instantaneous and connecting to IMAP server via TLS is very fast (1-2 seconds according to the log), I have to wait several seconds until I see new messages in folders with a large number of messages in them (some 35k messages but even folders with 5k-10k messages take noticable (and irritatingly long) time to update). This isn't how it used to work. The question is whether it is tunable, client or server side. -- Best regards, Robert Tomanek mailto:tbb...@mail.robert.tomanek.org Current beta is 4.1.9.1 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html
