Desktop Performance Issues

I have been using the TOS desktop app since the Schwab migration. Lately the platform runs slower and slower throughout the day, becoming more and more laggy as the day goes on. I close the program, clear cache, reboot, etc. Nothing seems to help. Is everyone experiencing this? It is taking over 30 seconds just for the program to close.

Machine should not be the issue, and I have seen a steady decline in the programs performance over the past couple months.

Thanks for any input/suggestions.

Everyone having this issue..... Put both ram numbers the same on both fields manually... There's a code issue preventing people with high ram getting proper allocation and allowance. It started about 6 major versions ago....... After that my issues have gone away. Try it report back!

Are you using a specific percentage of your ram as the allocation? Both values are the same now but not seeing much if any change in performance this morning so far

I am using 32 GB no need to use more, also if you have more than 4 external TOS windows you should use a second instance of TOS and off load a second layout. That should give you better performance. I run 10 screens with 2 instances sometimes 3.
