Speedy LiveCode

[dunbarx]

I have not changed my machine in years, and am using v. 8. on a 3.2 GHz iMac in OS 10.13

A handler like the following:

Code: Select all

on mouseup
   put the ticks into temp
   put "4" into foo
   repeat 10000000 --ten million
    add 4 to foo  --79 ticks
    -- get random(999) --86 ticks
    --  put 4 +  6 into foo -- 118 ticks
   end repeat
   answer the ticks - temp
end mouseup

Takes 79 ticks, or about 7.6 million passes through the repeat loop per second. The other operations are only a little slower.

This is well over twice as fast as benchmarks I made years ago, in v.6. Good news, and in RAM only, so am I noticing anything important?

120 ticks over "here" on a piece of junk I got for nothing:

Xubuntu 18.04

Intel(R) Core(TM)2 CPU 6300 @ 1.86GHz
Dual Core
8 GB RAM

nothing as in "This lump of something has been sitting around
for donkey's ages in my shop and nobody wants it, so do me a favour . . ."

I'll never complain about the speed of LiveCode beyond the occasional "That's too fast for me."

168 ticks on my 2006 iMac:

Mac OS 10.7.5 (Lion).
2.16 GHz Intel Core Duo
3 GB RAM

Certainly a lot faster than my ability to gulp coffee!

Hi,

This is well over twice as fast as benchmarks I made years ago, in v.6. Good news, and in RAM only, so am I noticing anything important?

Twice as fast as in LC 6? Sure you don't have any quirks in your data?

I tried it on my cheap (€ 50 as leasing return) dev machine (HP Compaq 6005 pro, built 2010, Athlon II X2 B24 @ 3GHz, 8GB RAM, Win 10-64 pro v1803), using my reference LC versions and each of the 3 options in your code:

Code: Select all

LC/ Task:	6.5	6.7.10	7.1.4	8.1.8	9.0.1
-----------------------------------------------------
"add 4":	50	41	88	128	135
"random":	78	75	100	145	174
"4 + 6":	116	80	111	188	224

Have fun!

MacMini (late 2014), 8 GB RAM, 2.6 GHZ i5, macOS 10.3.6, LC 9.0.1:

Code: Select all

-----------------------------------------------------
Ticks:
"add 4":	73
"random":	77
"4 + 6":	116
-----------------------------------------------------
Milliseconds
"add 4":	1211
"random":	1270
"4 + 6":	1939

I took your code, and put it into a little stack for testing, starting with Mc 2.5 starter kit

Made in Mc2.5 starter... Modified vers.

This box is running LMDE2 18.1, 4 gigs ram, and a 3 core amd cpu. All of the tests were run with the following system resources left before opening the various IDEs -

Conky...

I moved up through the IDEs from Mc pre-oss to Lc 8.1.2 on this machine. On to the tests...
........................

*Edit - just setup a vm to test 9.0.1 on debian testing, so grabbed that test as well -

Lc9.0.1 test...

*Edit 2 - just realized I should probably have mentioned all the results were testing only the add to foo line as the base

Edit 3 - Modified it a bit -

And here is MC with engine 5.5.4, the latest version I maintained as the MC poobah.

Thanks for running it Klaus, I don't have any 5.x series to test with

I'm still using LC 5.5.5 for general use in Windows 10.
System is Intel i7-8700k, 16Gb ram running Windows 10 64bit.

Dunbarx's code snippet in LC 5.5.5 takes 15 ticks.

Using bogs MC stack.

Running this on 'nix sure makes the older IDEs look speedy as heck.
6.5.2 vs. 8.1.2 -

6.5.2...

8.1.2...

Holy cats

The Transcript engine you are running

isn't that just a bit . . . ?

[bogs]

Think I should change it to "The X-talk engine you are running.." ?

I made it a standalone in 6.5 and 7.1, to see if there was any differences to note.

No IDE 6.5.2...

No IDE 7.1.4...

Art imitates life: a slow decline:

[richmond62]

And here are the standalone results (Xubuntu 64-bit, 18.04):

LC 8.1.10

LC 9.0.1

Yah, I saw that problem too Richmond. Beyond 8.0 (I think) you need to save the file in the current Lc IDE format before compiling it. To boot, you may have to compile it with 'nix64 and not 32, or you might get a shared library error.

v9 standalone (Debian Vm)

v9 64bit standalone...

*Edit - to get the v9 compiled 32bit 'nix version to run, your system needs to be setup for multi-arch (see debian multi-arch if your debian based), and from the command line you need to enter -

Code: Select all

sudo apt update
sudo apt-get install libgtk2.0-0:i386

Here is the 32 bit version of the compiled v9 standalone -
