Konqueror: Web form text field is slow

I have had this happen too but still haven't got down to what causes it.

Last night my machine suddenly went extremely slow. There were 11 konq windows 
open, 1 copy of acrobat and 2 copies of kate with klibido (15kbs download 
100mbs lan) running on desktop 2. I started up K's memory monitor. Getting 
menu up and the cursor to the right place was a challenge and after about 
10mins in started to run and showed that nearly all 1gig of memory was used 
and most of the 1gig swap space too. The machine had run with this loading 
for at least 15mins without any problems. The mem monitor showed that linux 
was continually swapping small chunks of code of about 9 Mbyte. I managed to 
close some windows - each taking a long time to close but it didn't recover. 
Not a kde problem but surely there must be a signal in the kernel to indicate 
that this is going on. I have to wonder about the decision making process the 
kernel uses in the swapping process too. From kde's point of view surely the 
user mouse and keyboard input should have a very high priority. The overall 
effect reminds me of typing ahead on overloaded mini's years ago.

I suspect that slow keyboard input is caused by disc activity so it may be 
worth loading the memory monitor and taking a look. I've also seen the spell 
checker take ages to highlight a miss spelled word under much lower loading. 
That's ok but lack of keyboard and mouse response is infuriating.

My system discs are raided 10k sata raptors (Intel on board) by the way so 
data rates are high. Suse10 has been running on them for ages but the 
partitioner reckons that they are an error. I'm wondering what will happen if 
I resize the partitions.
