I think I did that a while back... here it is:

Code region              Time    Pct    Invoked   Min(ms)    Avg(ms)    Max(ms)
overview write   01:37:51.460   6.8%     244059    15.044     24.058     55.547
overview write   01:46:16.920   7.4%     237849    17.734     26.811     41.979

(the first is the old, the second is the new).  So it got a little bit
slower.  For my purposes, it's not noticable, but I don't know if that
will also be true for everyone else.

I think the very small change is pretty impressive given that the old code
rarely wrote index entries to disk and the new code msyncs all over the
place.

Now that there's a full load on the server, it's gotten a bit slower:

overview write   02:38:18.656  11.0%     246679    14.195     38.506     59.892

which isn't surprising, since everything running on that server slowed
down.  But that number isn't comparable to the previous number.

1.7.2 was using overchan, so I unfortunately can't directly compare it to
the new code.  I'm pretty sure that the new code is slower to write than
1.7.2 was, since there are two files to write instead of one, but it's a
lot faster for reading.

But in any case, here's the full statistics from the old server followed
by the full statistics from the new server.  Note again, though, that this
is apples and oranges since the old server was a faster system
(dual-processor Ultra 2 compared to a single-processor Ultra 1) with
slower disk (SPARCstorage Array compared to an A1000).

The new system is going to be upgraded probably next Thursday.
