I repeated the test on both 64-bit versions to highlight the results. Two values are better with PB 6.30.
Result in one image:

Mimalloc is disabled on RaspPI for now, that's probably why it's similar for alloc stuff. I will try to activate it but I got some build issue with mimalloc itself so stay tuned.

A picture with normalized values even better!
It is weird that some use cases are only 2x better?
Does that mean it was already optimized or there is still room for improvement in 6.40?
Well, 2x better is huge, no ? The old system wasn't that bad perfomance wise, but it has some limitation and some very hacky implementation which made the maintenance hard. Also when the Thread mode was enabled (which is for most apps nowaday) there was an extra performance hit. Now, the perfs are the same in thread and non-threaded mode.
The benchmark doesn't include string functions, but some are much faster, like Len(), Right(), RSet(), Mid(), etc. Basically having an instant length info is very useful for a lot of commands.

Ok, I will redo my split() and join() speed tests, but many years ago it was 600x faster with comparememorystring() vs native PB string calls.
Thanks for clarifying where the new 2x comes from.

Can you test with threadsafe mode activated to see if there is some diffs ?

And Now for Something Completely Different...
I have a problem with ContainerGadget, similar to the one described here:
viewtopic.php?t=86735
Is there a chance to do something about this before the 6.40 release? Or maybe I'm doing something wrong?
Code: Select all
OpenWindow(0, 200, 200, 220, 150, "test", #PB_Window_MinimizeGadget | #PB_Window_TitleBar)
PanelGadget(1, 0, 0, 200, 120)
AddGadgetItem(1, -1, "Tab1")
ContainerGadget(3, 20, 20, 100, 50)
TextGadget(4, 20, 20, 50, 20, "text1")
CloseGadgetList()
TextGadget(5, 140, 40, 50, 20, "text2")
CloseGadgetList()
Repeat
Until #PB_Event_CloseWindow = WaitWindowEvent()
