Need confirmation on thinCore speed

**ErosOlmi** · 11-10-2007, 16:48

Hi all,

I think I've got some more speed improvements in thinBasic Core, enough significant to ask you for some tests.
If you have some spare time, can you please download attached thinCore.dll file (copy over the one you will find into \thinBasic\ directory) and make some speed tests using the scripts you will find into \thinBasic\SampleScripts\General\Speed\ directory?

Improvements should be all over the script execution and not specific to some particular situation. Mainly I've changed the way LONG numbers are handled inside Core engine. Previously I was using POKE/PEEK while this core has pointers to LONGs instead. If you will confirm the same improvement I've got (about 5/10%) I will change all other numeric types.

Thanks a lot
Eros

I ran Four tests, most of them are faster with the new dll.

If I had remembered to turn my Web browser off during the tests they probably all would be faster, lol.

The first Four images are BEFORE I changed the dll and last Four are AFTER.

Thanks a lot matthew.

Hey the first test, the one with 100000 different loop type seem very significant! Maybe too much.
Was the first script executed after some thinBasic run or was it executed as first thinBasic script during the day? It may suffer from some caching.

Ciao

Here are my results with modified test routines.

have fun.

Abraxas, no improvements but worst results in your case.
What a success I've got!

A little note: in you script USES "CORE" is not needed because loaded by default.

Before I ran the tests I downloaded the new preview version of ThinBASIC.

It was the first script I ran after installation.

Eros didnt think I needed it, thanks.

Can a script call another script?

**ErosOlmi** · 11-10-2007, 18:05

You can call another script by shelling a new process like any other shell command.
With thinBasic scripts you cannot make something like "chaining".

But this is an interesting idea :

Hi Eros,

seems nice here, about 10-20% speed increase in loops !
Just one thing - is it safe to use LONG instead of DWORD for pointers ?

No GPF or anything, just curious

Thanks a lot,
Petr
