Slow loading of recently generated NexusProcessed files

[Russell Taylor]

From Aziz:

Below, I found the reading of new nexus processed files very slow,

compared to old ones. I attach the corresponding files, which were generated at different dates given below:

09/25/2009 16:35 1,876,829 van_8mm_15x20.nxs (0.703 seconds) 10/05/2009 17:57 1,902,721 van_43004_6mm_15x20_30- 230ms_test.nxs (28.36 seconds)
