Description (partial)


In IOS-XR 3.8.1, performance of processmib is slower by several factors compared to earlier release
like 3.6 or 3.4.

If snmpbulkwalk is used to poll the processmib, the delay will cause other mib walk to timeout, so
it's recommended to use simple snmpwalk (not bulk) on processmib. It won't speed the processmib but
at least reduce the impact on other mib walk.
