Hi Team,

We are fastest in the benchmarks mentioned in the following Blink Commit, but I am raising this to see if this can be salvaged or if similar can be applied to further improve the performance or this is something already achieved and don't serve any benefit.

This is just to get input.

Performance Benchmark: https://jsfiddle.net/hr7Lm5jq/ & https://jsfiddle.net/x3kv4gut/

Just wanted to raise this for input.

Thanks!
