Workload C: Read only. The latency table is following for test C and since it was read only test hence there is no update latency figure here. The latency table shows that 99th percentile latency for Yugabyte is quite high compared to others (lower is better). This workload is 100% read. Again Yugabyte latency is quite high.

Briefly, what is the difference among: (a) undefined behavior Undefined behavior is what happens when your program tries to do something whose meaning is not defined at all in the C++ standard language or library (illegal code and/or data). You’ll get some valid result, but you won’t know what the result is until your code looks at it.

To get good results, we can use an important insight that is not documented anywhere at any length: we can use 64-bit processor instructions to do 32-bit arithmetic. There is no silver bullet but a simple C function can beat a state-of-the-art optimizing compiler. Where does this leave us?
