Benchmarking Mercury As The "Fastest Firefox Fork" With AVX, AES, LTO + PGO
Lastly with the Kraken results there still wasn't any real change from Firefox to Mercury. The only change with Kraken was with Firefox 118 where there was a nice improvement in the performance. Firefox 118 looks like it will be a nice upgrade on the performance front.
Not only was Firefox 118 often running faster than prior Firefox versions, but it was also generally consuming less power and showing to utilize less of the CPU than prior Firefox releases across the range of benchmarks conducted. The Mercury CPU usage and power consumption was similar to Firefox 115.0.2 for which it was derived.
So at least for my testing using a modern AMD Ryzen 9 7950X system with Ubuntu Linux, I am not seeing any real benefits out of the Mercury browser. For what it's worth with the Mercury performance page it notes the tests were done on an AMD FX-8370 era system so perhaps with much older hardware there may be better luck. In any event those wishing to learn more about Mercury can do so at thorium.rocks.
