Deleting an attachment will save the file in the attachment trash, which 
means copying the file in another place. You could try to disable the 
attachment trash to get a faster result, if you don't care about rolling 
back deleted attachments.

The time spent seems reasonable given that it involves disk I/O and a 
fairly large file. What could be done to improve responsiveness is to do 
all the work in the background, i.e. just start the file copy process 
and instantly resume the work. This means more work to ensure that 
future requests affecting that file won't interfere in a bad way.
