The problem I think with SFS is it gets bogged down with the recycle directory... I've always used SFS with the NORECYCLED option...
I never had any problems with it and when I moved to SFS2 it was VERY fast and still is... I am currently using SFS2 and JXFileSystem4 since I haven't bothered to clean off all my SFS2 partitions and reformat them...
Of course this probably won't apply to you but the tactic regarding SFS is valid... until very recently I never had a problem trying to recover something I accidently deleted... this is the risk I take to make sure my FS is swift and happy... LOL
Just don't remove any sanity checks before carrying out a delete operation (I did) if you still hit the ok button after it asks you if you're sure you want to delete it then by heck you WANT to delete it, surely!
