Hey Pallem, shame to hear of your sluggishness, but im happy to hear your coping with the device, When i initially got my device, i didnt do anything, just got wifi up and running immediately and updated all the latest firmware, everything is running amazingly.

Now what i haven't done is even tried the devel apps or anything from the xtras repos, but from what i understanding, using things from these two seems to install into the Root directory, which could cause potential slowdowns, for this there are ways of getting around it,apt commands after taking control of root etc, but i dont know too much about that .... yet.

There is a video of someone running 32 things on the N900 on youtube, thats when the device begins to stutter...lol! but 12-16 should run fine (i posted a screenie on one of the earlier pages, thats how i use my device every day.)

I had one unstable complete spike yesterday, this was unplugging USB without unplugging it from the phone itself, the device was 100% cpu full time, but still usable (Handshake gone wrong?) lol, after i unplugged from the phone itself things settled down!

Im trying to understand how CPU usage works, we have clocks 250mhz, 500 and 600mhz and the CPU reports percentage, i dont know if this is of total? or of current frequency.

I could understand your device going a bit slow with all them contacts with the IM service though haha, thats alot of pressure!

Currently my root is sat happily on 60mb, its gone up by 20 since yesterday, i believe the phone seens to be distrobuting and moving files nicely.
