enabling MTOM

Are there any downsides (performance, etc) if I always enable MTOM
even if I don't use MTOM feature?

TIA

Yes.    If mtom is on, we always setup the mime envelopes and such.   Thus, 
the messages on the wire a bit bigger (extra set of mime headers, boundaries, 
etc...).

Also, on the receiving side, reading is a little bit more expensive as we need 
to examine each byte read to make sure a boundary isn't hit.   Not super 
expensive, but probably measurable.
