279744 - Inactivity periods while retrieving large e-mails

Status: RESOLVED EXPIRED

When I try to retrieve large e-mails from a pop3 server, there are always long
periods of inactivity (like 10 or 20 seconds). Actually looking at the pop3 log
file, it is not modified during this inactivity time, and the network activity
is very low. Then a few kbytes of the current e-mail is downloaded and a new
inactivity period starts.
Note that even if it is doing nothing, mozilla's mail activity icon remains active !

Reproducible: Always

do you have a virus checker running? This sounds like a virus checker getting in
between mozilla and the pop3 server and slowing things down.

AFAIK, I am not using any virus checker. I currently use mandrake 10.1 with the
normal security level, without having changed anything to default checking stuff.
Anyway, I don't think the mdk free distrib actually contains such virus checker.

Would it be possible the pop3 server actually retains the e-mail while
spam/virus scanning ?

The slowness could be on the pop3 server side, you never know.  How large are
these e-mails? If the slowness occurs in the middle of downloading the message,
that sounds like something going on in the server - we fetch the message with
one command, and then the server sends the data all in one go. The only thing we
do with it is write it to disk...

(In reply to comment #3)

The slowness exists all the time and is independant of the size of the e-mails.

 The behavior is the following : mozilla downloads some kbytes in 1 second, does
nothing during 30 seconds, downloads some kbytes in 1 second, does nothing
during 30 seconds and so on ... as long as there are e-mails on the server.
Thus if an incoming mail is larger than, let's say 50 kbytes, it cannot be
downloaded from the pop3 server in only one such activity time. In contrary a
small e-mail is downloaded in only one "pass".

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
