Thanks for your observations. Well indeed that would appear not overly stressed at all.
Using RDP or console Windows TASKMANGER | Processes tab, how much memory Commit Size (you might have to add that column and tick show process for all users) does the coldfusion.exe grow to?
Also might be interesting to know is CF10 using java 6 or 7 (CFadmin > System Information | Java Version and Java VM Name)?
I hope the native tomcat library (APR) helps. Carl.
