After installing KB2829361 I noticed a significant delay in processing input requests. This was easily overlooked if you don't know what you are looking for. Before installing, if I started up a:
1. Tomcat Web Application Server (Windows 2003R2 Enterprise Server x64, the screen that displays shows the startup process and the overall time to startup a node would take just a little over 1 minute to complete. After the update, this same node and 5 others on the same machine W2K3 SP2, now took 6+ minutes to fully startup.
2. On my database server (Oracle 11g) Windows 2003R2 Enterprise Server x64, executing a simple query to get performance results:
SQL> set linesize 150
SQL> select size_for_estimate,buffers_for_estimate,estd_physical_read_factor,estd_physical_reads from v$db_cache_advice where name='DEFAULT' and block_size=(select value from v$parameter where name='db_block_size') and advice_status='ON';
The results of this query before apply patch KB2829361 would take less than a second to display the results. After applying the patch, it would take almost 30 seconds for the same query.
3. On my laptop with Windows 7 x64, there was a noticable difference for before and after. I used SI Software Sandra Lite to evaluate where the bottleneck may be and it was in the kernal/CPU layer and clearly shows performance numbers being worse than before installing the patch.
4. On another machine Windows 2003R2 Enterprise Server x32, I checked the before and after results of KB2829361 and again noticed a difference.
I also re-installed the KB to see if it was just a coincidence the performance has degraded and the results were identically the same. I have since uninstalled KB2829361 until someone can say there is a fix for this issue.
The differences on the 4 servers were identified by using Sunbelt Remote Administrator v3 to the server since I am in NC and the servers in MA & NH. Note that, the delays appear to be on the display side since this same process works fine without the KB.
