I run several Linux boxes now, including two FC4 machines. I do all my mail reading on them, now, though I leave messages on the servers and only download to my Windows box for archival. (I have mail archived as far back as early 90's) I've noticed a huge discrepancy in performance between Outlook vs. Kmail and I wonder what others are experiencing. Currently, I have over 20,000 messages on one FC4 box and nearly that many on the other. Leaving aside the question of why, here's my observation/question: With Kmail, my fedora-list folder, for example, currently contains over 13,000 messages. I leave my search bar open all the time. If I want to retrieve an old post that I remember as having pertained to a current problem, I can start typing in to the search bar and immediately, Kmail begins narrowing the search options and producing a list of relevant messages - I mean immediately - there is no lag, the response seems instantaneous. To search a folder in my Outlook archive, even a much smaller folder, takes many moments, sometimes over a minute, if the folder is 'large' - by large, I mean over a 1000 messages. For this reason, I have archiving turned on, and messages over 3 months old are sent to archive, but of course that then means multiple searches if I'm looking for an older message. So, my question: how large can Kmail folders get before they start to slow down searching? I find this performance remarkable, and I'm just wondering what the limits are? -- Claude Jones Bluemont, VA, USA
