RC2 is running in production without any apparent problems<br>
till now.&nbsp; Well its difficult to say at the moment how much speed<br>
gain is there unless the heavy duty batch SQL scripts are run by<br>
cron. <br>
<br>
Count(*) and group by on large tables are significantly (5x) faster<br>
and better error reporting has made it easier to spot the faulty data.<br>
eg in fkey violation.<br>
<br>
Will post the OSDB .15 versions' results on 7.3 &amp; 7.4 soon.<br>

Yes, it seems unrealistic to try to run the "client" on a separate
host from the database.

I got the osdb benchmark running last week, and had to separate client
from server. I had to jump through a fair number of hoops including
copying data files over to the server. The benchmark software needs a
bit more work...
