Subject [Patch]: Scoreboard as linked list.
Date Fri, 03 Aug 2001 02:26:28 GMT
Ok, I have finally finished this version of the scoreboard redesign. The
basic idea is to implement the scoreboard as a linked list. The design,
test results, benefits, and patch are at
Please check it out and give it a try. It performs very well.

The brief performance results for this patch are:
   Current Time: Thursday, 02-Aug-2001 13:32:45 EDT 
   Restart Time: Thursday, 02-Aug-2001 11:02:44 EDT 
   Parent Server Generation: 0 
   Server uptime: 2 hours 30 minutes 
   Total accesses: 2456532 - Total Traffic: 69.3 GB 
   CPU Usage: u42.52 s92.34 cu.29 cs2.35 - 1.53% CPU load 
   273 requests/sec - 7.9 MB/second - 29.6 kB/request 
   327 requests currently being processed, 172 idle workers

compared to the current cvs code (reported yesterday):
   Current Time: Wednesday, 01-Aug-2001 10:48:54 EDT 
   Restart Time: Wednesday, 01-Aug-2001 08:09:19 EDT

   236 requests/sec - 6.8 MB/second - 29.3 kB/request 
   190 requests currently being processed, 0 idle workers

There is a lot more info about the design, benefits, and test results
at that web page so rather than take up any more bandwidth, please
check it out. The patch applied cleanly to cvs head as of Thursday
at about 12:00 noon east coast time.

Also, please let me know if you have any problems getting at the page.
