Re: [Pythoncad-developer] New testing kernel

[<mat...@bo...>]

I Gertwin,

I have done some modification at the kernel structure to
improve the performance
and here there is the test.

We need to inprove the performance on the single operation
0.4 for a single operation is too mutch...  I think that i
can improve the code do get 0.0007 s
for single entity

Test made on w$7 os:
Old style Performance test
Create n: 1 entity in : 0.479778374389s
Create n: 10 entity in : 4.9313876202s
Create n: 100 entity in : 49.298951129s

New style performance test
Create n: 1 entity in : 0.000770127605866s
Create n: 10 entity in : 0.00181878469585s
Create n: 100 entity in : 0.0115031393396s
Create n: 1000 entity in : 0.110898375245s
Create n: 10000 entity in : 1.06068519964s
Create n: 100000 entity in : 10.6621433079s

Regards,
Matteo

Re: [Pythoncad-developer] New testing kernel

[<mat...@bo...>]

Hi Gertwin,
I Did some mistakes on time calculation 
those are the updated values


Test made on w$7 os:
No Bulk Operation (with commit and undo enable)
Create n: 1 entity in : 0.1890149854s
Create n: 10 entity in : 1.0234820464s
Create n: 100 entity in : 10.5052122664s

BulkOperation (Commit at the end and undo disable)
Create n: 1 entity in : 0.193075697126s
Create n: 10 entity in : 0.190634392615s
Create n: 100 entity in : 0.196410349659s
Create n: 1000 entity in : 0.320889925233s
Create n: 10000 entity in : 1.33172048646s
Create n: 100000 entity in : 11.4102046186s

I don't think  that we can have best performance ..than this
.

Regards,
Matteo

Re: [Pythoncad-developer] New testing kernel

[<ger...@gm...>]

Hi Matteo,

I like the performance of the bulk operation, I think that is fast enough.

The commit is very expensive for single updates.
Is it possible to let the program control the commit?

What I mean is, when the user wants to copy 100 elements, the program must  
commit all those 100 updates and inserts in one single commit.

Maybe something like this.
If we have our own transaction object that contains a list of modified  
elements.
The program can add elements to this transaction object.
The program calls a commit function in the kernel with the transaction  
object as parameter.
The kernel can commit all the elements within the transaction object in one  
single commit.

start pseudo code:

# get transaction from kernel
trans_object = kernel.getNewTransaction()
# add modified elements to the list
trans_object.addModifiedElement(element1)
trans_object.addModifiedElement(element2)
trans_object.addModifiedElement(element3)
...
trans_object.addModifiedElement(elementN)
# commit the changes in a single commit
kernel.commit(trans_object)

end pseudo code.

Also when the user wants to undo this action all modified elements are  
undone, not a single element per undo.

Regards,
Gertwin

Re: [Pythoncad-developer] New testing kernel

[<mat...@bo...>]

Hi Gertwin,

> The commit is very expensive for single updates.
> Is it possible to let the program control the commit?
Yes

this is the code for the bulk operation ..

    
    kr=PyCadDbKernel()
    startTime=time.clock()
    nEnt=100
    kr.startMassiveCreation() <-here i start bulkOperation
    for i in range(nEnt):
        basePoint=Point(10,i)
        kr.saveEntity(basePoint)
    kr.performCommit()        <- here i perform the commit
    endTime=time.clock()-startTime

In this case the commit was made at the end .....
So in case of dxf import we can use this strategy to speed
up the load of the data.

In this way no undo will be written ... so I have to think
at something else to record the undo for all the entitys.

May be I can create a relation table from undo end Entitys
to link one undoId with more entitys.

Matteo
