We've already given XAPI a server, and before we give it any more
hardware I would need some serious convincing that XAPI as it currently
exists is actually workable and scalable in some sensible way because as
far as I can tell at the moment it isn't.
As I understand it the database takes so long to load that if there are
any working servers they are way out of date, and even when a server is
working it can only serve a couple of users at a time which, when a XAPI
query can often take minutes or hours to run is clearly not practical
for serving a large community.
There are also issues with the run time that the code uses - it's
horrible ancient and crufty and requires various kernel security
features to be turned off.
