I can't reproduce such a behavior here, ist this issue still alive on your side? If so maybe you want to start thunderbird from the comman line to see some moer output. Regards Carsten
Bug#821812: icedove: High CPU usage with IMAP+SSL and iceowl+SSL-Caldav
Hi Carsten, meanwhile I'm using a newer version of Thunderbird, I've updated Debian from Jessie to Stretch and I'm using newer, more powerful hardware. So there is still a high CPU-usage while starting up Thunderbird, but it's about 10-15 seconds and not for a minute. I can test starting Thunderbird from a command line when I'm back at my Office-PC.

If you disable this extension and restart you see a significant quicker starting of Thunderbird. The delay with the c-g-p is related to the real time communication with Google servers while syncing calenders and task. This is more a upstream issue. You will see more if you start Thunderbird from a terminal. Regards Carsten

Package: icedove Version: 38.7.0-1~deb8u1 Severity: important Dear Maintainer, I've connected an IMAP-account with SSL (Port 993) and the calendar (iceowl) with a SSL-caldav-calendar from the company. When I start icedove one core of my CPU (i7-620m) is at 100% for about one minute. In this time icedove is almost unusable. When I disable iceowl everything runs fine, on the other hand, when only iceowl is using the calendar and no email-account is configured everything is fine too. I only found an older bugreport for the same problem but it seems to be fixed, maybe it's a similiar issue. https://bugzilla.redhat.com/show_bug.cgi?id=488066 Unfortunaly I'm only allowed to use connections with SSL so I can't test if this is also happening without any encryption. -- System Information: Debian Release: 8.4 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages icedove depends on: ii debianutils 4.4+b1 ii fontconfig2.11.0-6.3 ii libasound21.0.28-1 ii libatk1.0-0 2.14.0-1 ii libc6 2.19-18+deb8u4 ii libcairo2 1.14.0-2.1+deb8u1 ii libdbus-1-3 1.8.20-0+deb8u1 ii libdbus-glib-1-2 0.102-1 ii libevent-2.0-52.0.21-stable-2 ii libffi6 3.1-2+b2 ii libfontconfig12.11.0-6.3 ii libfreetype6 2.5.2-3+deb8u1 ii libgcc1 1:4.9.2-10 ii libgdk-pixbuf2.0-02.31.1-2+deb8u4 ii libglib2.0-0 2.42.1-1+b1 ii libgtk2.0-0 2.24.25-3+deb8u1 ii libhunspell-1.3-0 1.3.3-3 ii libpango-1.0-01.36.8-3 ii libpangocairo-1.0-0 1.36.8-3 ii libpangoft2-1.0-0 1.36.8-3 ii libpixman-1-0 0.32.6-3 ii libsqlite3-0 3.8.7.1-1+deb8u1 ii libstartup-notification0 0.12-4 ii libstdc++64.9.2-10 ii libx11-6 2:1.6.2-3 ii libxcomposite11:0.4.4-1 ii libxdamage1 1:1.1.4-2+b1 ii libxext6 2:1.3.3-1 ii libxfixes31:5.0.1-2+b2 ii libxrender1 1:0.9.8-1+b1 ii libxt61:1.1.4-1+b1 ii psmisc22.21-2 ii zlib1g1:1.2.8.dfsg-2+b1 Versions of packages icedove recommends: ii hunspell-de-at [hunspell-dictionary] 20131206-5 ii hunspell-de-ch [hunspell-dictionary] 20131206-5 ii hunspell-en-us [hunspell-dictionary] 20070829-6 ii iceowl-extension 38.7.0-1~deb8u1 ii myspell-de-de [myspell-dictionary]20131206-5 Versions of packages icedove suggests: ii fonts-lyx 2.1.2-2 ii libgssapi-krb5-2 1.12.1+dfsg-19+deb8u2 -- no debconf information
