Regarding the performance problem, you should indeed half the time required
by turning off debugging, but the real problem is worse than that.  I posted
a message to this mailing list a couple of days ago (Subject: Performance
problems with RPC messages over 20k), where I did some benchmarks based on
message size.  It looks like the time required to process the message
increases at a geometric rate relative to the message size.

As yet no-one else seems to be interested in this problem, so the best thing
I can suggest is to break your string up into 20K chunks.

Please let me know whether you find out anything more about it.
