I had some performance issues that I couldn't determine the cause of. It eventually resolved itself though...it might have been a network congestion problem.
What happened was that whenever I had an incident say for printing, there was confidential information in it but the message never popped up. Once 60 seconds had elapsed the document didn't print and it took about half an hour for the incident to appear in the Enforce server. The next day it was fine though...I don't remember changing anything =/
Other than that, I found that there are some lags in producing HTTP POST incidents in the Enforce Server. I'd have an incident at 4pm and the time that it registers as reaching the Enforce is like 10am the next morning. That was only with certain URLs though...others worked out fine.
Lol I just reread your post...these issues are actually with 10.5, not 9...can't hurt anyway I guess
