When loading a large multiperiod workspace, such as INTER00027729.nxs, Mantid freezes for several seconds. This is highly visible to the users, and takes up a non-trivial amount of the total loading time.

This freeze has been profiled to be coming from FileLoaderRegistry::chooseLoader. For a more detailed explanation of where the time is being spent, see comment 3 of #11483. You're encouraged to do some further profiling work yourself to verify this.

Ticket objective:

  • Optimise chooseLoader to run against INTER27729 in a second or less.
