Do you mean 60 Mbit? If so, then that's a very good result for only 30% CPU.
It means that the padlock is doing it's job in making crypto acceleration.
Without padlock I am seeing about 50% CPU use with 25 Mbit in + 25 Mbit out.
There's a way to measure the uses of the hw acceleration given by the Via Padlock, if it's at 10% of it's capacity or 100% ?
There is no way, the only hint you have is the general CPU load.
That's the point, i want to measure how the padlock hw accel is performing, to understand if it does hit it's limits or not.
I think that we need to find a way
It is not a separate accelerator device with its own throughput limits, it's just a set of additional instructions in the CPU. Hence as long as you see CPU load less than 100%, then no "limit" has been hit. Or if you see 100% CPU use, then there's your answer, even with the padlock support it is now saturated.
