We are having issues with our clients on our network randomly losing connection or having very high latency and slow page loads. I called into TAC and they weren't very helpful. An hour on the phone and I didn't feel like they were looking in the right direction.
Here is a snapshot from our system log. we have about 2500 users online at any given point. Does anything look alarming in this log that would be a cause for concern? We are running 6.5.3.4 on a 7210 controller with 291 AP's. We have dual 10 GB uplinks as well. Where else could I look for strange slow performance across the entire network?
