Hi all,

I just applied to CVS a modified version of Murali's patch to do faster 
opens.  This could be a big help for access patterns with lots of opens 
and closes.  Basically the patch gets the iod info into the same message 
as the acknowledgement, which is a big win when using TCP.

Todd, Charles - I had a look at the code to see if we were mistakenly
closing iod connections if we didn't have any files open, and we don't.  
So I'm running out of easy ways to try to speed things up for your
application (although you seem to have a reasonable solution already).

Regards,

Rob
