I'm switching to fstrim, it is quicker than the deletes.
fstrim consistently takes about a minute to run on a 40GB
volume.

I see that the running of fstrim was already discussed
http://oss.sgi.com/archives/xfs/2011-05/msg00338.html.
Please add something to the FAQ about using SSDs. It would be great if
people could see the recommended mount options and fstrim crontab entry
(or other option) for running xfs on a SSD.
It's a publicly modifiable wiki. Feel free to add what you've
learned here to a new FAQ entry - others will come by and correct
anything in it that is inaccurate....
And it is already there:

Feel free to expand it.
