Non-default option; this may conceivably affect performance.

These definitely effect performance, much more in 5.x and 6.x (at the
10-20% level) than 4.x.

This definitely effects performance on 6.x since it makes your
filesystem giant-locked, which may also interfere with your network
processing.
Please retry without. Also make sure there are no other diagnostic
