what "services" are you turning off? also, your initial claim was that 
modules that weren't even "turned on" were slowing your site down...

well, yes and no. drupal in general is quite fast for a system of it's 
complexity... there are some gotchas that will kill performance though.

given what the two of them do, and the required code to do them ... was 
this really surprising at all?

indeed. performance tuning is hard. particularly in a system like Drupal 
where so much depends on the underlying layers (LAMP, etc)... throw in 
UML (which has some behavioural gotchas of it's own) and you've got a 
lot of things to think about.
