resource hog

i've read through the forums, seen a few topics...
but...
this program really does slow things down.
don't really understand why, if it's supposed to give priority to other progs.
but, crap, makes my system move like it's walking through treacle!!
not a great system,
pentium d, 2.8 mhz each cpu.
3 gb ram
windows 7 home 64

I guess you are still at the initial download of the current block chain.
until your blockcount is around 66k you still have to download the blocks and verify them. this takes quite some hard-drive performance, so maybe thats what is slowing down your system.

i'm sorry, but no!
i started at 666## something, ages ago. now up to 66812
and got my 5 freebies 
still got max cpu usage?

It will always use max CPU to generate but the generating thread is scheduled at a low priority so it should yield to other processes. I can compile code and do other things on my windows machine with 0.3 running and it doesn't seem to slow it down for me at least.

thanks for the quick answer 
i have bitcoin running, gomez peer and BOINC.
there is definitely a major slow down.
if i have bitcoin running, and click on gomez icon, it takes a good 30+seconds to open. should be instantaneous!!

while i'm at it.
probably totally wrong place, but,...
248 confirmations and my address has changed. why has my address changed. please? 
HELP!!!
hehe 

It generates a new address and puts it in the main window for you if a payment is received for the previous address. This is so each time you click 'copy to clipboard' to send it to someone, it's easier to get a unique one. The old one is still valid and it's still in your address book.
Try renicing bitcoin and see if it helps. Find the pid in top or ps and then renice +19 1234 where 1234 is the pid.

I don't think their is any renicing under Windows.

In Windows, you select the process in the task manager, right click, Set Priority. Set it to BelowNormal or Low. That shouldn't make a difference though.
If you turn off Generate Coins, does the CPU usage go flat? That would confirm that all the CPU time it's taking is generate, which is idle priority already.
It could be it's slow just because you have too many things running at once and you're out of memory. When you switch from one thing to another, it has to page it in from disk.

thanks every one for your help 
have tried manually setting priority to below normal, and it plays nice!! but stays at 100%
also, when i turn off generate coins, cpu usage drops to zero!
turning generate on sends cpu back up to 100%
