Test procedure
- 
Calls were evenly distributed between all available cluster nodes.
 - 
All calls had a duration of 60s.
 - 
MAP queries were required for 10% of calls.
 - 
Benchmarks were taken over a two-hour test run, with an additional 15 minutes for JIT compilation.
 
Summary
| Cluster size | Calls / sec | TCAP messages / sec | Events / sec | Results | 
|---|---|---|---|---|
One node  | 
5,000  | 
31,000  | 
42,000  | 
|
Two nodes  | 
10,000  | 
62,000  | 
84,000  | 
SLEE events per second dramatically exceed the TCAP message count in the table above because each inbound TCAP message generates:
- 
one event for itself;
 - 
a dialog state change event, if appropriate (e.g. the first TC-Continue received after sending a TC-Begin indicates dialog acceptance); and
 - 
one event for each TCAP component the TCAP message contains (e.g. an operation or a response).
 
Outbound messages do not trigger events.
Types of graphs
The individual test results include the following types of graphs:
