Background

The goal here was to investigate the speed of BufferedMatrix.justRMA() as a function of the number of arrays processed between 10 and 1250 HGU-133 Plue 2.0 arrays and compare it to performace of justRMA()

Source code (note takes very long time to run)

Results

Discussion

Not surprisingly justRMA() was generally faster than BufferedMatrix.justRMA(). However, on the test machine justRMA() failed to process at 1250 arrays, and notice the speed at 1100 arrays is not in pattern with the lower number of arrays. This is likely because justRMA was making heavy use of swap memory.
