Convert to MD is slow for some diffraction cases

[martyngigg]

This issue was originally TRAC 11276

Leighton Coates has an example where ConvertToMD is extremely slow. This needs profiling to understand why.

Batch modify all SSC tickets to critical priority (this will also show up as an update for all those already as critical)

Assigned to Martyn to do the profiling and find the bottleneck (unless transfering the data is too hard). Implementation may be elsewhere depending on results

I have emailed Leighton to ask for an example

@martyngigg would be good to get the test case for this. Might be interesting to see if what @igudich has been doing fixes the performance.

@OwenArnold We had been waiting on an instrument scientist in the US to give us a test case. @peterfpeterson Do you know if there are still issues here? We captured this quite some time ago...
