The amount of ram used by uv or udt is configurable - There are a whole heap of parameters and it is a subject in its own right.

I have a management report that pops up on an Ipad/Iphone/Droid or whatever. The UV process that gets fired goes in and grabs Sales data for 30 store locations and spits it back. Using firebug, I can see how long the php script that calls the UV process takes. It does its reads, etc., and then bottles up the data and sends back a string (1.2 KB in size) in JSON or XML or whatever in around 800 ms to 1 second consistently. So I guess thats consistent with what you were saying. Just thought I would add to the info. However, I did notice that UV on AIX is limited to 256MB of RAM per session. So I wonder if Linux would behave differently? Ironically, I'm in the process of setting up a UV Linux machine for our production system, because AIX 5 support is ending soon. So I guess I'll find out soon enough.
