    PDM Very Very Slow Speeds

    Jose Saldana

      Dear SolidWorks/PDM Users,

       

      Our company recently migrated CAD Systems.  We were using 2006 Co Create, but we are now live with SolidWorks 2016, SP5.0 and PDM 2017 SP3.0.

       

      We had a consulting company help us take our legacy data and migrate into the vault.  Since the day we launched, PDM performance has been extremely slow.  It takes a very long time to check things in and out, change status and even more so when loading the BOM.  I've seen it take 5+minutes to check-out / check in a part file or a drawing and some assemblies have taken 20+minutes just to check out or in.  We have contacted our re-seller and they've looked into it, but have not been able to identify the issue nor offer us a solution.  I know they are still investigating the issue and have began communicating with SolidWorks too.  In the meantime, I figured I would put this on the forum, perhaps, some of you might have seen this before or have ideas / suggestions.  We have a feeling it could be related to our legacy data, but we are not for sure.  We currently testing / troubleshooting that ourselves.  Something has to be wrong, it's extremely slow.

       

      Any help, ideas and suggestions are much appreciated.

       

      Regards,

          From the EPDM admin tool on a client machine, under the Local Settings category, open the Log File.  If there are a lot of errors, what are the error codes?

            I'm curious as to what the solution to this problem was. I currently have had a large project being checked in PDM that takes a VERY long time. with 100 parts and 5-12 min per part will take forever. I've also contacted my VAR and am waiting for a response to take this matter further and investigate.

            I have SW 2017 SP5 with PDM 2017

              2017 or any version does not typically behave in that manner.

               

              I would look first at the latency between clients and server if this is happening across the board. 

               

              Do you have AV or third party security or data sync programs running? On clients or server? To check this, simply turn them off and see if behavior changes. I like to use Microsoft Process Explorer to turn off third party apps in the shell of Windows Explorer.

               

              For latency... A quick ping test will tell you a snapshot in moment but wireshark or similar product will give you a broader picture.

               

              Is the migration ongoing while your team is still working on production files?

               

              Hopefully answering these questions will give you clues to get closer to the source of the issue.

                  To build on what Nadia is saying, we had an issue with our security software that is installed on our machines. It has a real-time file checking function that will scan any files being transferred or opened. This caused a significant delay in getting large assemblies as well as opening them. We had to add solidworks file formats to the exception list and everything went back to normal.

                  The first place I would look is network speed and topology (both physical and logical). Often a poorly configured router (even a smart router) can send packets halfway around the world (or your facility) which increases latency. PDM is pretty robust with file transfers, but part of that is more error checking than your regular save/open over the network. If the network has a lot of traffic and therefore packet conflicts, then all of the data transferring will take longer.

                   

                  At my last job my workstation was physically 10 feet from our PDM server, but my packets were being routed over the fiber link to our main office building across the parking lot, through a couple switches there, then back to the PDM server. Once we fixed the routing tables in the switches things sped up dramatically.

                   

                  In any case I would start with your VAR for troubleshooting as most have a PDM specialist on staff.

                   

                  I was talking to Michael Burks with MLC-CAD last night at our user group meeting and he mentioned that one of the big fixes for PDM in 2019 is changing the script that checks file information. Up till 2018 it queries every version of every file for properties/info which takes an extremely long time for large assemblies with lots of unique parts.

                    Hi,

                    20+ min to check in or out... Damn !

                     

                    have you got an SQL maintenance setup ? this could improve perf, check this link  : http://files.goengineer.com/BestPractices/EPDM%20SQL%20Maintenance%20Plan.pdf 

                     

                    You can also writ an SQL query the see the defrag % on the table index on your server (to see if a maintenance is setup)

                     

                    ALWAYS do a test on a test server AND a backup.

                     

                    Maybe not the solution, but it can help.

                      I've actually been in talks with management and they were actually wanting to upgrade all our engineering computers and servers. So, In the meantime looks like i'm in the limbo until these changes are in effect.

                      This is great information to know! I will definitely be taking these in consideration if the problem persists and possibly open a ticket with my VAR.

                        Yes, the big PDM fix in 2019 is changing the script that checks file information. Our company has been working closely with SolidWorks personnel on this issue. Our PDM setup is correct, but PDM is struggling with the complexity of our setup. Our models contain a lot of referenced files, so this has been a big reason for our slow performance.  Latency also adds to the problem. We are going to have follow up meetings with SolidWorks at SWW19 on the issue.

                            Jose,

                             

                            Do you have any further info on this after following up with SW?  My team seems to be experiencing a similar problem, with an overwhelming number of reference files in parts/assemblies/drawings.

                                I have talked to someone that has recently had this conversation with SolidWorks.   In a nutshell, SolidWorks is improving it's testing in high latency environments.  They made some fixes for this in 2019 SP2 and are going to hopefully have some others fixed in 2019 SP3.   If you have latency issues now and are considering 2018, please test with 2019 SP2 as well.   It may be best to skip to 2019.

                              Are you running SW PDM pro or  standard? what's your Vault size or number of files in the Vault? and how many users?

                                Just wondering why you're running SW2016 on the 2017 PDM?
