04/19/2022, 9:12 AMso its all precompiled basically - b
best-agent-85158
04/19/2022, 9:12 AMThing is, without compiler cache, hxcpp is as fast, or even sometimes faster then hl - b
best-agent-85158
04/19/2022, 9:13 AMFor some reason haxe never uses compiler cache on my PC and HL takes about 20 seconds to compile - p
powerful-morning-89
04/19/2022, 9:13 AMUhm, you're forgetting about the native compilation step. - b
bright-gpu-74537
04/19/2022, 9:14 AMwho? - b
best-agent-85158
04/19/2022, 9:14 AMAt compile time - p

04/19/2022, 9:14 AMShahar. - b
bright-gpu-74537
04/19/2022, 9:14 AMi dont think thats accurate, hxcpp compilation is massively slower than HL - b

04/19/2022, 9:14 AMWhen compiler cache works - b
bright-gpu-74537
04/19/2022, 9:15 AMthe compiler cache helps loads but an initial, fresh compile can take minutes - p
powerful-morning-89
04/19/2022, 9:15 AMIf HL takes 20 seconds, then Hxcpp would take 20 minutes - b
best-agent-85158
04/19/2022, 9:15 AMIt takes 10 seconds most of the time, 40-50 secs for a clean build - b
bright-gpu-74537
04/19/2022, 9:16 AMand am i right in thinking, thats primarily because HL has everything precompiled into hdlls? - b
best-agent-85158
04/19/2022, 9:16 AMHl takes 20 secs because I have a caching problem with my PC altho hxcpp seems unaffected by it - b
best-agent-85158
04/19/2022, 9:16 AMWhich makes think hxcpp doesn't use the compiler cache, or doesn't rely on it that much - b
best-agent-85158
04/19/2022, 9:17 AMBTW if you're wondering @powerful-morning-89 , my cpu is ryzen 5 5600x - b
best-agent-85158
04/19/2022, 9:17 AMSo pretty decent - b
bright-gpu-74537
04/19/2022, 9:17 AM40-50 seconds for a clean build, especially using openfl (and haxeui) means things are certainly verrrry cached - b
best-agent-85158
04/19/2022, 9:18 AMBit compiler cache is disabled... - b
bright-gpu-74537
04/19/2022, 9:18 AMthen maybe you have fastest SSD known to man? (which i think is the bottle neck of c++ in general) - b
best-agent-85158
04/19/2022, 9:19 AMIt's a pretty high quality nvme so maybe - p
powerful-morning-89
04/19/2022, 9:19 AMHxcpp emits C++ which is slow to compile. HL emits bytecode, and thus doesn't need a native compilation. Hdll's don't help that much, your average lime app spends far more time compiling generated code, than compiling hxcpp code. - b
best-agent-85158
04/19/2022, 9:19 AMIt is fast, turns on windows in like 4 seconds - b
bright-gpu-74537
04/19/2022, 9:20 AMinteresting, bytecode... yeah, that makes more sense - p
powerful-morning-89
04/19/2022, 9:20 AMI'm sure I can make Linux boot faster /s - b
best-agent-85158
04/19/2022, 9:20 AMOfc,but windows in 4 secs is impressive - b
bright-gpu-74537
04/19/2022, 9:21 AMi sorta forget that HL is VM sometimes... and hxcpp isnt - p
powerful-morning-89
04/19/2022, 9:21 AMThe slow part of Hxcpp is native compilation. Generating the C++ code is as fast as generating HL bytecode. - b

04/19/2022, 9:21 AMyeah, when i get a new computer going to deck it out with NVMs - b
bright-gpu-74537
04/19/2022, 9:22 AMyeah, makes perfect sense... HL emits a bunch of byte code that its then interpreted at runtime by its VM
