Any 1 experience bad latency with HP 2520-24-PoE Switch

[YenLin]

Hi there, we've got 6 HP 2520-24-PoE Switch in our environment.

I have been using veriosn S14.03, S14.30 and S15.XX but all of them have very high CPU and bad latency problem.

Sometimes, the latency will up to 2000ms and the telnet takes almost 15 sec to get response after issuing sh run ,sh flash or sh vlan.

Is there any 1 have same situation?

Now, we upgraded them to version S.15.09.0012

I have never been experiencing any bad response time like this.

In a lan, I expect to get less than 5-10 ms, I can torrent up to 30ms.

But not up to like 100ms for any 1 time.

Hello, I've seen similar behavior in networks with loops.  Can you share your config and or what your a snapshot of what your environment looks like?
