This is now reduced as much as we can on the FreeCAD side I think. There is still some memory leak somewhere in pivy, though. But this has ow been minimized as much as possible.

I suggest we either close this now, as there is AFAICS not much more we can do in the FreeCAD code itself, or leave it open, removing the 0.17 target, in case someone wants to dig into the pivy code later, as after all, it has become more or less our baby (or Looo's :) ) now...

In any case I'll remove the 0.17 tag

Out of curiosity what makes you believe that there is a leak in pivy?

This one fell far below my radar... In any case the problem is not big anymore, more several optimizations to do, so better to reschedule for 0.19...

@yorik, what's the status of this? is that something that could be done now?

It needs testing again, basically. I have not observed this anymore, but it needs to be metered precisely to make sure.

I think i've observed a huge augmenting of memory used when changing from 2d to 3d and back into 2d several times on the dimension object... Do you experience the same?
