The best variant to compare the speed of application generated by compilers is to write data intensive, non-OS related activities.
For example, calculation of long equations in the loop, working with big chunk of arrays of numbers and etc. without any code optimisations - i.e. using pure language semantics.
Strings are different story, as C++, PB and FB may differently process string data, so results may vary.
The real fights are: number crunching, accessing and manipulating arrays and matrices.
Coming back to True Basic - yes, I've tried this just because of I'm fan of BASIC language in mind
A decade ago, my friend asked my to help with lots of TrueBasic examples from his Theoretical Physics course in university, so I ordered TB Bronze disk to compile and run examples.
Well, this version does not creates the a standalone executable, but uses an external DLL, like VB.
I haven't had a chance to check the exe file, but it seems run faster.
TrueBasic 6 Gold - quote from their web site:
Platforms: Windows XP, Vista (32- and 64-bit), 7, 8, 8.1, 10
Building on the power and capabilities of Silver Edition, Gold is a complete tool for creating new programs in elegant and easy-to-understand True BASIC. Gold Edition includes more than 2,000 pre-written libraries in both compiled form and original source code. New libraries are included for SQL database use, sockets, PostScript integration, and linking compiled C libraries into your BASIC programs.
A features-loaded Basic.
