Yes, that seems possible. Operations working on large numbers of small files always take a long time.

Subject: File delete rate

Apologies if this seems a bit vague - I'm in need of a quick sanity check. 
Doing a qtree delete - it's taking 'a while'. 
This seems to be because it's deleting every file at a rate of 50-100 files per second, and there's about a million files in the qtree.

Is that a 'reasonable' rate of deletion? (This is using an API based 'file-delete-file' operation, if that's relevant).
