Hello. I've noticed a severe performance regression in a JavaScript Parsing libraries <http://sap.github.io/chevrotain/performance/> benchmark i've created. This is a *pure* CPU JavaScript engine benchmark, so the cause should be V8, not Chrome.
On Chrome Stable Version 67.0.3396.99 (Official Build) (64-bit): With *V8 6.7.288.46 *I am getting *~2,500* Ops/sec for the Chevrotain library. While On Chrome Canary Version 69.0.3495.0 (Official Build) canary (64-bit) with *V8 6.9.423 *I am getting* only ~1,000 *Ops/Sec I also saw a similar issue with Chrome beta/dev channels. That is a pretty severe regression... What should I do now? Where can I open a bug? How can I help? - I've played around with the source code of the Chevrotain but have not found any workaround/mitigation yet. - I've thought about reproducing the issue in node.js but there is no node.js version with V8 6.9 yet. Cheers. Shahar. -- -- v8-dev mailing list v8-dev@googlegroups.com http://groups.google.com/group/v8-dev --- You received this message because you are subscribed to the Google Groups "v8-dev" group.
