Not all browsers offer the same level of performance as each other.
Performance factors include support for the latest JavaScript features as well as support for graphics engines and hardware acceleration.
Performance can also vary depending on the hardware of your setup.
Newer and more expensive hardware is generally faster than older or cheaper hardware.
The general way to find out how well your setup performs is to use benchmarking software.
There are plenty of benchmarking tools to test the performance of various pieces of your box hardware.
surfing app extensions can also interfere with performance results so you should ideally temporarily disable them.
Benchmarks
The websitebrowserbench.orgoffers three different web client benchmarks designed to test different things.
The three benchmarks are JetStream 2, MotionMark, and Speedometer.
JetStream 2 is designed to test the performance of modern features of JavaScript and web assembly.
Speedometer is a general test of how well your web app performs across a range of standard web features.
The ARES-6 benchmark, availablehere, tests the performance of various modern JavaScript features.
The test consists of 6 passes over four tests, each test having multiple iterations per pass.
The results are presented with the first run speed, slowest four iterations, and overall average.
