Since 5088 my Windows XP has been thrashing the disk like nothing I'd ever seen
before. Memory load was high (440 Mb virtual on a 192 MB physical machine) but
not  extremely unusual. According to Task Manager Java and Freenet weren't
taking large amountas of memory.

I put it down to being associated with general network issues.

But with 5089 it was still a problem. My computer was virtually unusable and I
don't think my node was performign well.

I wasn't getting any error messages about out of memory (although periodically
Windows would advise that my Virtual memory was too low and increase it). The
node was working, but like the whole computer was very slow, and the disk was
going all the time.

THE SOLUTION:

In the file flaunch.ini (located in \program files\freenet ) I changed the line

JavaMem=default

to become:
JavaMem=192

Rebooted and restarted Freenet and now my node is working the best I've ever
seen and the disk thrashing has stopped.

I don't know if 192 is a good choice.

I don't know why "default" became bad - too many node references? Crassoing some
threshold? I did increase by datastore size a week earlier...or was it the
BigInteger(?) optimisations introduced in 5088?

I'm posting this in case anyone else finds it useful, and also so that if
someone has a chance to think about what "default" means in flaunch.ini it sure
wasn't a good choice for me.
