Also note that alacritty's benchmark are throughput oriented, not latency oriented. The benchmarks measure how fast it can tear through data, not how quickly pixels change on screen.

But, rendering the entire terminal buffer is slightly overkill when only a few pixels changed, and the time it takes can end up significant on weaker devices driving high resolution displays.

As a result, Alacritty doesn't have the best "time to light" performance, and there have been long debates in the issues about it.
