Thanks for your responses..

@pycage: Its to a new memory card which I put into the N810. I dont have a card reader to test it independently of the N810, but I do have another memory card that I could borrow and try to rule out the card.. I'll do that today and see if it makes any difference.

@xopher_mc: Yep I mean the CPU on the n810. I've done what you suggested, and this is what I've come up with:

When its not doing anything:

Code:

Mem: 124632K used, 2164K free, 0K shrd, 16696K buff, 37884K cached
Load average: 0.85 0.45 0.19

When I'm copying a file from my laptop to the N810 via USB, to mmc2 (my memory card in the N810 - not the built in one)
I'm getting only 1.2MB/second, and the results of top are:

Code:

 1114 user     SW<    31436  1086  0.0 24.7 maemo-launcher

So I can see its not maxing out the CPU.. I thought it was based on the load-applet which showed 100% (not sure why).. but still the 1.2MB/s speed is very annoying. Any ideas if the results of top indicate a problem?

Thanks!
