Hi,

My report was bogus - I had forgot to do a cp...

I have now retried. With good results.
The only thing that worries me is that dbench results
has declined a little from earlier test9.

System is responsive even during mmap002,
and run of mmap002 is much faster then before :-)

Summary:
+ No lookups, kills, good performance...
= I like it.

More testing in evening.
