Add profiling support #2

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What is the proposed new feature or improvement?
Snofyre needs some kind of profiling support and a framework for monitoring 
performance

Version Information:
 -- Snofyre version      : 1.8
 -- Operating System        : Any
 -- MySQL Server version  : Any

Please provide any additional information below.
Adding profiling support for Snofyre services will allow performance to be 
monitored remotely (ideally via JMX)

A Core2 Duo 2.53GHz Laptop will generate (during a single continuous session) 
1000 flavours of anaemia in 7 minutes (1 every 0.46s), another 1000 in 8 
minutes (1 every 0.48s) and a further 1500 in 16 minutes (1 every 0.64s). 
Compute performance in a single session tails off rapidly beyond around 3000 
items generated, presumably because the Java heap is approaching full: the heap 
finally explodes somewhere after 4000 items generated in one session. 
Performance metrics appear to be the same for each new SnoFyre session, and is 
not obviously degraded if modest quantities of previously generated data 
already exists in the backend DB  - currently tested up to 54k unique 
expressions, created over multiple different sessions generating 3500 items 
each. Metrics suggest performance, if heap problem was fixed, may be a 
sustained generation rate of around 8,000 patients per hour compute time.
