Benchmarks #165

Closed pauldraper closed 7 years ago

pauldraper commented 7 years ago

(1) Do you happen to have the code used for the bencmarks published anywhere?

(2) You link to Twirl for Play 2.2, but 2.3 saw a significant impovement in template performance.

(3) I published a ScalaTags/Twirl benchmark at pauldraper/scala-html-performance with the latest versions of each and a similar tempate. Good news! ScalaTags seems 10-25% faster than Twirl.

Some incomplete perf tests are in here https://github.com/lihaoyi/scalatags/blob/master/scalatags/jvm/src/test/scala/scalatags/text/PerfTests.scala#L1

Good to know Scalatags is still faster; probably have Rory Graves to thank for his work speeding things up recently =)

While Scalatags perf is already blazing fast, it still isn't fast enough for all use cases. e.g. it was giving me slowdowns when re-rendering large sections of a page client-side, at 60FPS, while scrolling. I'd welcome more improvements, but nothing much else to "fix" here
