For fun...  How about a look at this... For fun... I'm having some speed
issues with SoapCore in conjunction with Seaside, i.e., using it with
Seaside so it's kind of on topic....

Using Soap against .Net.  It's my only access to my SqlServer database, and
recently I've noticed that a large part of my performance issues seem to
stem from Soap Decoding.  I'd like to know what you think.  Here's a Message
tally on a result set that takes about 1.7 seconds to return from the
service, but nearly a minute to decode 192 objects...

- 54494 tallies, 54557 msec.

	incr		623 totalling 361ms (1.0% uptime), avg 1.0ms

	root table	0 overflows

Which leaves me staring at #do: wondering where to proceed from here.  I
emailed the author hoping maybe he'd have a better clue, but if anyone likes
tweaking code... Here's some code that needs tweaking.
