Hi,
I have question about DNS cache performance.
How much DNS query per second can handle ROS?
Its some SW limitation in ROS or can use all resources up to 100% CPU?
And can use only one CPU or all CPUs in system?

Thanx for answer.

Moly

I think there is a maximum of 100 pending upstream queries at the same time. So, when you get a lot
of cache misses and your upstream DNS is slow you may hit that limit.
