currently it takes about 1 hour to extract the stats from 1250 gating hierarchies. Originally we thought it was due to the rbind operation. after Rprof, 56% of the time was spent on getData method (load flowFrame from gating hierarchy). The flow data is only needed for calculating MFI .Given that the data is sitting on disk in ncdf, it is not surprising to slow down the entire process.

However, there might still be room to improve the speed regardless of this factor. We can do this after other features are stable.
