I cannot find the main cause of slowness, which occurred while updating preview of formatting options. MultiFileSystem.findResource took only 0.6% of time, and was called from MimeLookup, so it would be difficult to fix it. The rest of slowness was caused by UI rendering and class loading.
It seems that the system was under heavy load. Closing.
