I received several ping plotter results from a client who has been experiencing slowness in a hosted application. After having a colleague re-evaluate the results, it seems pretty evident there are latency issues in the client's local network. The hosted application relies on Citrix to conenct to the datacenter, so anything over 100 ms ping times can be considered a performance issue, especially when there are several active users.

The Ping plotter was too big to attach, so I've taken a couple of Jing Screenshots below. What you're seeing there is a consistent pattern:

1. Starting at 10:24 AM: http://screencast.com/t/bmoYZ9JRSWvx
2. Starting at 10:09 AM: http://screencast.com/t/d6rJ30b22t
3. Starting at 9:42 AM: http://screencast.com/t/7FJ97kxKk1Kv
4. Starting at 9:06 AM: http://screencast.com/t/fuZCgMiQKyVj
5. Starting at 8:27 AM: http://screencast.com/t/R4zpZlf1aUxA
6. Here's an example of extreme latency starting at early in the morning (5:46 AM), for example: http://screencast.com/t/HCeah2Ejw6hN
a. Here's a zoomed in version of that. We can see a direct correlation between the first hop and the final destination: http://screencast.com/t/e7XMUHMn. I believe this indicates that the first hop could be the root cause of the slowness.



Now, the client claims to give low priority to ICMP traffic. I can understand if that was evident in the ping plotter by Packet loss, but even if it were given priority, wouldn't the latency still show up?

Thanks!
