Hello, I'm using the c-client library as part of a client application, and was hoping for some advice on how I might change the way I'm using it to improve performance. Specifically, I've run into some slowdowns when I use the mail_sort function to retrieve a sorted list of message UID's from a large mailbox (several thousand messages). What appears to be happening is that the mail_sort is dutifully executing an IMAP search, but subsequently calling what appears to be the equivalent of a mail_fetchfast on each message individually: 0000000e SEARCH UNDELETED UNSEEN NOT (HEADER X-Priority 1) * SEARCH 26 27 28 29 30 31 32 <...snipped over 1000 UID's ...> 1205 1206 1207 1208 0000000e OK SEARCH completed. 0000000f FETCH 26 (UID INTERNALDATE RFC822.SIZE FLAGS) * 26 FETCH (UID 46 INTERNALDATE "10-Aug-2005 21:33:47 -0600" RFC822.SIZE 20687 FLAGS ()) 0000000f OK FETCH completed. 00000010 FETCH 27 (UID INTERNALDATE RFC822.SIZE FLAGS) * 27 FETCH (UID 47 INTERNALDATE "10-Aug-2005 21:33:47 -0600" RFC822.SIZE 20687 FLAGS ()) 00000010 OK FETCH completed. 00000011 FETCH 28 (UID INTERNALDATE RFC822.SIZE FLAGS) * 28 FETCH (UID 48 INTERNALDATE "10-Aug-2005 21:33:48 -0600" RFC822.SIZE 20685 FLAGS ()) 00000011 OK FETCH completed. 00000012 FETCH 29 (UID INTERNALDATE RFC822.SIZE FLAGS) * 29 FETCH (UID 49 INTERNALDATE "10-Aug-2005 21:33:48 -0600" RFC822.SIZE 20686 FLAGS ()) 00000012 OK FETCH completed. 00000013 FETCH 30 (UID INTERNALDATE RFC822.SIZE FLAGS) * 30 FETCH (UID 50 INTERNALDATE "10-Aug-2005 21:33:48 -0600" RFC822.SIZE 20687 FLAGS ()) 00000013 OK FETCH completed. 00000014 FETCH 31 (UID INTERNALDATE RFC822.SIZE FLAGS) * 31 FETCH (UID 51 INTERNALDATE "10-Aug-2005 21:33:48 -0600" RFC822.SIZE 20687 FLAGS ()) 00000014 OK FETCH completed. 00000015 FETCH 32 (UID INTERNALDATE RFC822.SIZE FLAGS) * 32 FETCH (UID 52 INTERNALDATE "10-Aug-2005 21:33:48 -0600" RFC822.SIZE 20687 FLAGS ()) 00000015 OK FETCH completed. <... etc etc ...> Any suggestions or advice on other calls or perhaps different cache settings I could try to speed this up a bit? I figure there must be some way to either pre-fetch the internaldate (which I'm sorting on) or at least batch the fetch calls up somehow. Thanks! Andrew |
