I normally leave threading disabled. While it is a nice feature, I've
found on larger folders, it's a serious killer when it tries to read
all the mails and thread the lot.

Not really. I have 5 or 6 that are in excess of 40k emails :)

PHP Caching engine might reduce load on the web servers, but it isn't
likely to help much with the IMAP server. What was the performance
like without the imapproxy?

That is usually a good assumption, especially when you have server
side sort enabled. You might want to double check that, and double
check that the sort features are being passed on by the proxy (us a
traffic sniffer such as ethereal).
