Editor SDK x64, peformance of saving documents SOLVED

[tnickel]

Hello,

Recently i was tasked with upgrading our usage of the Editor SDK from x86 to x64. We went from version PDFXEditCore.x86.dll version 6.0.321.0 to PDFXEditCore.x64.dll version 7.0.327.1. Everything seems to work fine, however we noticed a large increase in the amount of time it takes to save documents, especially as the documents get larger. I am providing some code snippets that we are using. I have a PDF file I can send you folks that i have been using to test and that i used to gather the below metrics, but it is too large to upload here (~60 MB). The only modification I made to the document while gathering the metrics below was adding a single bookmark to the first page of the document. The 'IPXV_Document.Save()' metric indicates the amount of time spent waiting just that method to evaluate, while the regular 'Save' metric includes the time to evaluate 'IPXV_Document.Save()' + all of our client logic. All code presented below is written in VB.Net

Code: Select all

AxPDFXEdit.OpenDocFromPath(String file, ICab oReadOnlyParams)

file = a file in the temp folder of logged in user of the server hosting the application (e.g C:\users\{user}\AppData\Local\Temp)
oReadOnlyParams= nothing in most cases, in some circumstances is set before loading the document via the following :

Code: Select all

            oReadOnlyParams = AxPXV_Control.Inst.CreateOpenDocParams()
            Dim pOpenParamsRoot As ICabNode = oReadOnlyParams.Root

            Dim secPerms As Integer = PXC_PermsFlags.PermF_All And Not (PXC_SecurityPermissions.Permit_Copying_And_TextGraphicsExtractions Or
                                                                        PXC_SecurityPermissions.Permit_Printing Or
                                                                        PXC_SecurityPermissions.Permit_HighQualityPrinting)

The following code is exactly the same as used in the x86 implementation

Code: Select all

AxPDFXEdit.OpenDocFromPath(String file, ICab oReadOnlyParams)

file = a file in the temp folder of logged in user of the server hosting the application (e.g C:\users\{user}\AppData\Local\Temp)

Code: Select all

            oReadOnlyParams = AxPXV_Control.Inst.CreateOpenDocParams()
            Dim pOpenParamsRoot As ICabNode = oReadOnlyParams.Root

            Dim secPerms As Integer = PXC_PermsFlags.PermF_All And Not (PXC_SecurityPermissions.Permit_Copying_And_TextGraphicsExtractions Or
                                                                        PXC_SecurityPermissions.Permit_Printing Or

So for some reason, after the upgrade we are seeing much better results (~10x better) when loading documents, but much worse results (~10x worse) when saving them. I also tried implementing a stream-based saving solution based on your 'FullDemo' for the Editor SDK, however that seems to perform about the same with given our circumstances. Please let me know if i can provide more information or clarify anything. Thanks for your time.

Hello tnickel,

Have you tried the 327.1 x86 dll? If so, how does it behave comparing to the x64 one?
Also, do you have your license key applied? The save can take much more time, when we are putting our demo labels in case of no license or expired key.

Cheers,
Alex

Hello,

I have not tried the latest x86 DLL. I will try that today and get back to you on how it performs. The code to register our license key has been running on the development workstations I have been testing on, However, I am seeing the demo watermarks being applied to my documents. I assumed the license key can only be applied to a set number of workstations, and we have them reserved for workstations in a higher environment. I will try to test against a workstation where the license is being applied correctly, but it may take a bit.

Thanks

I tested with version 327.1 of the x86 dll, and am seeing a similar performance degredation on saving as with the latest x64 dll

Perf: IPXV_Document.Save() Time: 00:02:07.7230457, Documents: 1, Pages: 1969 WorkingSet: 899588096, Paged: 837390336

I will update you about the licensing in a few hours

Hello tnickel,

If you are seeing the watermarks - then the increased save time can be explained with their placement as they are complex objects. If you pass the valid key for the new SDK version - then no watermark will be added and thus the prolonged save won't happen.

Cheers,
Alex

Hello,

Thanks for your time. I will check with my supervisor, and we will either use the version of the x64 license that our key is valid for (6.0.321.0) or we will purchase a new key and use the latest DLL. This ticket is resolved from my perspective.

Thanks again
