Thanks for the pointer, Bill. I had not seen this work. Your question may be moot. My old eyes aren't what they used to be but squinting at the screen capture of the latency test results, the sampling period appears to be 1000us and the latency appears to range between 0.9681 to 68.798, hence we're looking at a range of 968us to 68798us. This is huge compared to, say, the < 10us Intel Atom results posted to our Wiki. I hope the situation gets better with time, because I like having choices. I'm just not holding my breath:-) Regards, Kent ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
