This is the final post inspired by Bityota ( bityota.com. Figure 8. Some Latency Metrics. When we combine these advantages we see that a 10X-100X advantage is conservative. The botto...

Surprisingly my hearing didn't get permanently damaged, though I did crack a windshield and shake off my rear view mirror a few times. I still have one of these. According to the study,...
