PROCESSOR INFO: 

The Keck reconstructor process run on the k2 aoserver 
Which is a dual processor Sparc Sun-Fire-V240 

The sparcv9 processor operates at 1280 MHz,and has a sparcv9 floating point processor. Physical Memory size: 2048 Megabytes

BENCHMARKS:

The IDL profile command was used to benchmark the Keck reconstruction tool that calculates the 
new reconstruction matrix as the pupil illumination changes.

Results represent 2 reconstructions 
A full reconstruction happens in about ~2.7 seconds 
Most of that time, about ~1.4 seconds, is spent in the IDL routine INVERT

Some additional overhead to load new reconstructor into Real-time system not captured in 
these tests.
