OSE Infrastructure

Throughput - and Current OSE Throughput

Says 250 users per core
OSE is quad core - so we can handle 1000 concurrent database requests? Does that mean 1000 requests every second?
How long does a database request take?
If we can handle 1000 database requests - how many concurrent users is that? Would that make it 60k users simultaneously, because a request takes 1 second?
Optimal server cluster is 3 servers - [2]
wikipedia has 350 servers? [3]
Absolute max for a single server is 65k users connected, but really dependent on server specifications? How long is a connection - is it only during a database request? [4]
1000 users at a time is for 4 GB RAM? [5] Does that mean that we are likely to handle 16k simultaneous users?
