Poor performance after first scan

I’ve noticed some poor performance after a first scan that I’m trying to understand. My first scan runs well, between 40 and 50fps. I’ve done some somewhat long scans of 45k+ frames with no issue, utilizing 55gb of system RAM. However, when I close the first scan and begin a new scan the performance drops to ~10-15fps and doesn’t improve. Memory usage is 45gb at the start, so it doesn’t seem to be entirely unloading the previous session or something. I walked away from the software once while a scan was paused and returned to 74gb of RAM in use, so it seems to be doing something even when scanning is paused.

If I restart the software, it performs well again until a second scan.

This is on a Xeon E5-2696 v4 (22 cores, 44 threads) with 128GB RAM and a Quadro P4000 GPU that is not being used and running Revo Track 5.7.1 on Windows 10.

Hi! Thank you for your feedback. We will continue to optimize and improve the software’s performance. Currently, we recommend that you restart the software and create a new project scan.

Hi @jhov 45K of frames is considering a very big file compared to almost 4 regular scans.

I did not had that issue in the past while testing Trackit, but I never collected 45K of frames in one run either as I usually prefer small sections for better accuracy that was never bigger than 20K of frames . I will check it this weekend to see if I can recreate that issue myself .

It has more to do with the software and the system than the scanner itself and it is still improving like Gloria already said .

I will let you know if I can recreate this on my system.

Another data point.. I bought a laptop for use with the Trackit to keep it a bit more mobile and I don’t have the issue with performance when using it. I just got it so I’ve only done some small test scans, but so far it performs the same scan after scan on the laptop.
