I don't know, low-end devices usually have tiny L1 and L2 caches. Switching from -O3 to -O2 sped things up by a few percent on an old Core 2 Duo laptop. It has a small L1 cache compared to a modern desktop but it's still huge in comparison to most low-end devices. If I were the OP, I'd experiment with -O2 and -Os and fastidiously benchmark with perf. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
