KMail slow? It may be a feature, not a bug…

KMail saved searchesRecently, I experienced KMail becoming unusably slow. With every navigation action, especially when deleting a mail, it came to a grinding halt for several seconds. Since I have a years long backlog of mails and mailing lists, I thought the reason was KMail reaching its limits in mailbox size.

So I made up my own mind about archiving my old mails, which is not exactly straightforward because KMail doesn’t offer an integrated way of archiving. When I was done, I noticed that there was not that much of a speed improvement as I had hoped for.

At the end, the culprit turned out to be a feature of KMail, which is to save your search queries and keep the result updated against modifications. Once these saved searches are deleted, KMail is back at full speed and responsive as ever. The screenshot shows how to delete the search folders.

All this is on an ancient KMail 1.9.5 using KDE 3.5.5.

Kubuntu Gutsy on Toshiba Tecra 8000

Tecra 8000 windowsMy Tecra 8000 is an ancient notebook with a 366MHz Pentium II processor, a 6 GB harddrive and an installed maximum of 256 MB RAM. Kubuntu 7.10 installs nicely on it, albeit very slowly.

Overall, I’m quite happy with the result. The systems feels faster than expected and is a perfect fit for its designated purpose, which is browsing the web and emailing. Application startup times are long, but once loaded, even a monster like OpenOffice is quite useable. There was only one major installation problem, namely getting WPA encryption to work with my PCMCIA WLAN card. [More…]
