@gorplop @eric @jae @m0xEE @phnt @sendpaws Because shitty JavaScript JITs are all optimized for x86-64 (especially if you're using some Chrome thing because Chrome was developed to run on Google servers before it started being another spyware vector) and ARM has different cache coherency guarantees and pipeline behavior. There's also less redundancy: things better farmed out to the GPU or FPU haven't been added to the ISA and compilers tend to shit the bed on what actually is there. On top of that, phones tend to be aggressive about saving power and lowering the clock to avoid heat, in Apple's case especially because they make money from an "app" but not from the web. Lots of shit going on.
