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.
