Firefox 68 Performance Is Looking Good With WebRender On Linux

Most dramatic in this testing was the MotionMark performance out of Firefox 68.0 Beta when enabling WebRender... For this benchmark it's a night and day difference performance-wise.

Also benefiting but much less with WebRender on Firefox 68 was the Basemark benchmark, which is about 3% faster.

The ARES-6 performance improved in Firefox 67 but is flat with Firefox 68 Beta. Of course, WebRender principally benefits the DOM/graphics tests and for the JavaScript benchmarks won't mean much unless any peculiarities in the code path.

The aging Octane benchmark saw a regression in Firefox 67.0 but is recovering somewhat in the Firefox 68.0 Beta.
