I recently updated to the new version of Solidworks 2019 because I was excited to gain access to some of the new features. Unfortunately, things took a turn for the worst. After rolling out the new version my team and I noticed an immediate and pronounced slowdown in the speed and performance. It was as if we had taken a step back. The new version of Solidworks seems sluggish to start and moving and selecting things feels halted.
I wanted to look at this issue with a fair comparison so I took one of my unused workstations and did a complete reinstall of windows and then ran both versions one after the other with a model we have here in our company. The model is a large assembly with more than 1600 mechanical and electrical components. It also includes several detailed injection molded parts with complex surfacing. Great for taxing Solidworks!
Here are the results of startup time, assembly opening time and rebuilding a part. It clearly shows that Solidworks 2019 is slower and significantly so in some areas.
I also took the time to run the performance benchmark for both installs of Solidworks and you can see the results here sho vast differences. I have a question into SolidWorks to make sure they did not change something int he performance benchmark but it appears that the benchmarks are the same.
I will keep you posted on what I find.
