Hmm, that might sound like I'm talking out my ass ...
Consider an app that displays the UUID of all guests in a list. It
calls GetUUID() for each guest. With 100 guests you get figures like:
+ Direct HV calls - 500us
+ Proxy - 3ms
+ XML-RPC proxy - 100ms
+ Proxy over network - 10s
+ XML-RPC proxy over network - 10.1s
So, the app seems snappy even with this number of guests until you run
it over the network. At this point we optimise by adding a
ListDomainUUIDs() call and this speeds up the local case too. At no
point should we worry about the XML-RPC.
Cheers,
Mark.
