The original test on my computer with DisableDebugger and compiling without the debugger give me 9.695 seconds
The User_Russian's test with DisableDebugger and compiling without the debugger give me 4.406 seconds
The NicTheQuick's test with DisableDebugger and compiling without the debugger give me 0.260 seconds
Best regards

Hi,
I did some tests,
but I do not understand the results ?
I use PB 5.62 Final x64 on my old programming laptop ... I like this PC
If I start the program and check the taskmanager,
I see that PB is only using 23% of cpu time even when there is a lot of idle time ?
Why ?
Marc,

Marc,
Sounds like a quadcore CPU with a software which utilitizes a single thread only. 3 of 4 cores cant participate so 25% would be the maximum you could get in the summary display. Switch do show each single core in a graph and see

The original code without the debugger (DisableDebugger shouldn't have an effect in this case):
13 758 ms
The original code, with the debugger and DisableDebugger:
13 916 ms
There is a small, but consistent difference. In other scenarios, there are actually big differences, especially when calling PB commands. When the debugger is turned off from the menu, the optimizer is turned on in the compiler (I think), and the library commands behave differently.
With debugger:
107 001 ms

Maybe it's also the reason why JavaScript could be faster than a compiled program, parts of the js code being executed on different cores. Threading is then very important...

Yes, it would be interesting to see the JS code. JavaScript compilers use inference engines that ascertain the datatype of a variable when it's initialized. If you take FireFox for example, iirc there are three levels of execution:
Interpreter (Functions that are only run once)
Baseline compiler (Warm code - A quick compile to byte code)
IonMonkey compiler (Hot code - A further more optimized compile generated from the byte code of Baseline)
If you change the datatype of a variable in JS that's running in FireFox it can slow down execution a lot because that routine will get kicked back down to the interpreter even if it's hot code (i.e. a routine that's being called repeatedly during execution). SpiderBasic's type checking should prevent developers from falling into that trap.

I'm not saying it's the case in this instance but when Mozilla were experimenting with asm.js it did outperform C++ on a Binary Trees benchmark.

Original code took 19s here (with debugger disabled from the menu).
Could you post the SpiderBasic code too?
Your test results are very surprising (Java and Go faster than C++??)
Note: Nicthequick's version completed in 0.2s.

I confirm, SpiderBasic completes it in about 2 seconds.
Really surprising.
@Fred, if you could comment on this, it would be great
PS: I'm using Google Chrome on Win 10 x64.
