No :( It's pretty relevant that GC in JavaScriptCore was written for JavaScriptCore. In particular, JSC doesn't focus on optimizing binary size, memory usage, etc... for embeddable devices so I would expect the performance characteristics to be dramatically different from that of Duktape or XS6.
True but if block_ptr<> is 10x faster than the Mark & Sweep GC then I think we got something perhaps worth investigating.
Analyzing the performance of a computer software is really hard. I've been working on WebKit for six and half years and I'm still surprised by the kind of performance issues we encounter and the difference in the performance characteristics between different CPU architectures, the number of cores, and the spec of a particular CPU.
I hear you. I am the one porting WebKit and all the dependencies on different CPUs where I work.
But my point is if I can't get something notable then it is what it is. -Phil _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
