[LON-CAPA-admin] load averages / min requirements?

Hi Peter,

Not exactly as usage levels, and problem complexity can be a bigger
 influence at times.

Here we are running 

- a Quad Xeon 1.5 GHz 6GB mem for the library server
- 5 dual Xeon 1.8 GHz 4GB mem for access servers
- 2 dual Xeon 3.0 GHz 4GB mem for access servers

The 1.8GHZ machines worked well for up to about 150 simulatenoeus
active users.

I expect the 3.0 to work well up to 250 active users but haven't seen
that occur yet,

1.2.0 has some nasty speed issues. 1.2.1 corrected problems with this,
1.2.1 is significantly speedier doig some very common operations
(NAV screen, displaying discussion, answering problems)

Just upgrading to 1.2.1 would seriously help.

That machine should be fine.
