I’m experiencing very high CPU and Memory usage when running ForeUI (and while no other Java application are running at the same time).
Just browsing thorugh the pages in a not complex plot makes the CPU usage jump to 98 %, and while working in ForeUI I’m experiencing lag. Things are not running as smooth as they used to. If I stop using ForeUI for a moment, CPU usage goes to 1 %. I think that 675 MB of Memory is also a lot for opening a single plot with 7 pages and not much behaviour. There a no loops or anything like that.
I’m using a brand new laptop with i5-5300U 2,3 GHz with 8 Gb RAM and Windows 10 64-bit installed.
Hi Ulrich, does this problem happen on all plots? Or it only happens on specific plot?
I don’t have Windows 10 on hand, but my ForeUI works quite well in Windows 7, and the CPU usage is much, much lower than yours.
The issue has partly disappeard.
- The huge CPU usage issue is gone. The CPU usage no longer stays above 90 % but drops to just above 0 % if I leave the plot open but stop working in it.
- The memory usage issue, however, remains. The memory usage keeps increasing if I switch between pages in a plot. I would expect the memory usage increase to some point when the content of the pages has been “loaded”. AsI type this comment I have a 7 pages not-complex plot open, and memory usage has increased to above 600 MB. Isn’t that higher than you would expect?
I just realized that I have maybe wasted your time, because I’m not running Windows 10 64-bit. I’m running Windows 7 64-bit… (I’m running Windows 10 on my laptop at home, but I don’t use ForeUi on that one…). Sorry about the confusion.
I still have a memory issue though, and I have experienced the CPU usage issue again today… :o/
Have you had a look at this issue? I still have both a memory issue and experience very high CPU usage (that does not drop as long as ForeUI is open) :o/
I’m running launch.jar, so I guess it is not a JVM issue, right?

I really loved it here but are there any recent updates? Thanks https://newbraunfelsfencecompany.com
