Performance regression

[Mansour Ayouni]

Hello Mahmoud,

I hope you are enjoying your vacancy...

When returned, can you please check the accuracy for this #TODO I have in Softanza codebase about a regression performance between Ring 1.22 and Ring 1.24:

This function just loops over the list and checks for non numbers:

func IsListOfNumbers(paList)
    if NOT isList(paList)
        return 0
    ok
    nLen = len(paList)
    for i = 1 to nLen
        if not isNumber(paList[i])
            return 0
        ok
    next
return 1

The same issue is observed on Ring 1.25.

All the best,

Mansour

Hello Mansour

I don't see this issue; I tried the program using Ring 1.25

It's done in 14 milliseconds (i.e. 14ms)

decimals(3)
t1= clock()
? IsListOfNumbers(1:100_000)
t2= clock()
? (t2-t1)/clockspersecond()

func IsListOfNumbers(paList)
    if NOT isList(paList)
        return 0
    ok
    nLen = len(paList)
    for i = 1 to nLen
        if not isNumber(paList[i])
            return 0
        ok
    next
return 1

Output:

1
0.014

Hello Mansour

Also, using Ring for WebAssembly, it's still fast (done in 16ms)

Mahmoud

Hello Mahmoud,

You are right! The issue is related to internal staff in Softanza that I'm searching for...

I'll keep you informed...

THANKS A LOT!

Best,

Mansour

Hello Mahmoud,

The problem is so strange...

When I write the code in a fresh new Ring file, no issue. I takes 0.018s on my machine.

When I just load stzlib, the issue is observed: 10.910 seconds!

But when I profile stz loading time it's just 0.6 seconds...

All the best,

Mansour

Note how I used a different name for _IsListOfNumbers()_ to avoid any call to anything from Softanza, it's just Ring code...

Hello Mansour

>> "When I just load stzlib, the issue is observed: 10.910 seconds!"

This happens because the Range Operator create the list by allocating for each item one by one

This is fast when we have enough items in the memory pool

Loading StzLib consumes most of these items in the memory pool 

To have better performance, use the List() function

Example:

load "stzlibconfig.ring"
load "stzlib.ring"

decimals(3)
t1= clock()
mylist = list(100_000)  // Allocate memory block for all items instead of using the memory pool 
for t=1 to 100_000 mylist[t] = t next
? myIsListOfNumbers(mylist)
t2= clock()
? (t2-t1)/clockspersecond()

func myIsListOfNumbers(paList)

    if NOT isList(paList)
        return 0
    ok
    nLen = len(paList)
    for i = 1 to nLen
        if not isNumber(paList[i])
            return 0
        ok
    next
return 1

Output:

1
0.025

Hello Mahmoud,

Using Ring 1.25 daily, while working on the Graph Module of StzLib, which contains networked manipulations of nodes and their relations, I observed a general performance enhancement up to 30% compared to Ring 1.24.

I never had any bugs or regression until now.

Best,

Mansour

For example, this code instantiates a stzDiagram object, which is itself a child of stzGraph, then calls stzGraphRules for applying visual rules on the nodes (a different color for each price range), and then fires the Graphiz DOT engine to generate the  DOT diagram image.

Ring 1.25 made it in half a second compared to Ring 1.24 which does it in 0.70 (s).

Which is very encouraging.

All the best,

Mansour
