           Summary: Claws mail became very slow
           Product: Claws Mail
           Version: 3.8.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Other
        AssignedTo: users at lists.claws-mail.org
        ReportedBy: koshikov at gmail.com


I can't remember the moment when it happened - but now I can't use claws-mail
with my gmail account - it is very slow. First I thought that problem related
to huge number of messages in folders, but after deleting half of them - the
problem remain. I even create new forder and copy about 10 messages - claws
slow down on this folder too. Here is some time range:

[10:47:06] IMAP4< 9 OK Success 
[10:47:06] IMAP4> 10 STATUS Portmone (MESSAGES UIDNEXT UIDVALIDITY UNSEEN) 
[10:47:14] IMAP4< * STATUS "Portmone" (MESSAGES 11 UIDNEXT 12 UIDVALIDITY 66
UNSEEN 0) 
[10:47:14] IMAP4< 10 OK Success 
[10:47:14] IMAP4> 11 SELECT Portmone 
[10:47:18] IMAP4< * FLAGS (\Answered \Flagged \Draft \Deleted \Seen Junk
$Forwarded NonJunk) 
[10:47:18] IMAP4< * OK [PERMANENTFLAGS (\Answered \Flagged \Draft \Deleted
\Seen Junk $Forwarded NonJunk \*)] Flags permitted. 
[10:47:18] IMAP4< * OK [UIDVALIDITY 66] UIDs valid. 
[10:47:18] IMAP4< * 11 EXISTS 
[10:47:18] IMAP4< * 0 RECENT 
[10:47:18] IMAP4< * OK [UIDNEXT 12] Predicted next UID. 
[10:47:18] IMAP4< 11 OK [READ-WRITE] Portmone selected. (Success) 
[10:47:18] IMAP4- [fetching flags...]
[10:47:18] IMAP4> 12 UID FETCH 1:* (FLAGS UID) 
[10:47:23] IMAP4< [FETCH data - 382 bytes]

As you can see - from time mouse clicked on forder "Portmone" and when the
message is actually displayed - elapse about 17 seconds. This folder has only
11 messages.

Stracing the process I see a lot of:
poll([{fd=5, events=POLLIN}], 1, -1)    = 1 ([{fd=5, revents=POLLIN}])
recv(5,
"\1\1\303\253\0\0\0\0\256\0\0\0\4\0\240\2\254\1\244\2\254\1\244\2\4\0\0\0\0\0\0\0",
4096, 0) = 32
recv(5, 0x83da1a0, 4096, 0)             = -1 EAGAIN (Resource temporarily
unavailable)
recv(5, 0x83da1a0, 4096, 0)             = -1 EAGAIN (Resource temporarily
unavailable)

Where 5 is FD for unix socket. Netstat show it like:
unix  3      [ ]         STREAM     CONNECTED     1754748  

The problem is definitly not related to internet channel - it's fast and from
web interface messages displaing immediately. 
Tried to disable all plugins(gtkhtml and notification) - still slow.
Tried to downgrade to 3.8.0 from 3.8.1 - slow.

Can somebody help with this ?
