Firmware V1910-CMW520-R1511 - High CPU usage and very slow web-interface

[nborisenkov]

I update a firmware on my HP v1910 and 3com 2920 switches to Firmware V1910-CMW520-R1511 and noticed that the web-interface and login time became very slow. On 3com switch CPU usage increased to 8-14% from 1-3% and on v1910 switch CPU usage increased to 7-20% with default configuration. Login to 3com switch take 6 seconds, login to HP switch take 16 seconds to view the Summary page.

I have exactly the same problem, also with newer releases like R1512P05 and R1512P10.

There are some features wich I would like too use, but the switch is unuseable with newer releases after R1111P01.
