Summary: Composer is very slow when replying/inline-forwarding
e-mails with a long body
Product: kmail2
Version: 4.8
Platform: Ubuntu Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: composer
AssignedTo: kdepim-bugs at kde.org
ReportedBy: itsef-admin at brightsight.com
Version: 4.8 (using KDE 4.8.0)
OS: Linux
Any time a mail with a long body (>1500lines) is being dealt with, Composer
becomes very slow for both opening and navigating within the text. While doing
so, Kontact thrashes the CPU up to 100%.
Reproducible: Always
Steps to Reproduce:
1) Select a mail with a long body (tried with > 1500lines)
2) Choose "Reply" or "Forward inline"
Actual Results:
The composer window opens and remains inactive (grey) for several seconds -
delays up to 10s have been observed. When open, navigating within the message
body is also very slow - e.g. jumping from the end to the top (Ctrl-Home) can
take 2-3s, again while thrashing the CPU. This makes dealing with long mails
very cumbersome.
Expected Results:
Composer should pop up quickly and be responsive within a short time.
Navigating within the message text should be smooth and not dependent on text
length.
- Set-up: Kubuntu 11.10 with either the original 4.7.4 packages or the
Kubuntu-ppa 4.8.0 packages, IMAP account, NFS4 home directories, akonadi
working with a central MySQL server.
- The bad performance was seen with both Nepomuk disabled and enabled.
- When using "Forward as attachment", Composer appears more or less instantly
and is much more responsive - the slow down seems directly related to the
length of the message body.
