Hi Florian,
The memory usage depends on the types of keys and namespaces.
We have not experienced that many concurrently open windows.
But given that each open window needs several bytes for its timer, 2M open
windows may cost up to hundreds of MB.

Hi,
that sounds very useful. We are using quite a lot of timers in custom windows.
Does anybody have experience with the memory requirements of, let’s say, 2
million concurrently open windows and the associated timers?
Thanks
Florian
