Describe the bug
I have a workload where I visualize about 10 small (200x200) images and tensors at at about 20 Hz.
With rerun 0.16 the visualization was basically running in realtime without problems.
After upgrading to 0.18 (both library and desktop app) ingestion speed is significantly slower and manages maybe ~0.5 Hz. The slowdown is so extreme that data keeps trickling in for minutes after the source program was already closed.
There only seems to be a problem with ingestion speed as replay when scrolling through the timeline is unaffected.

Desktop (please complete the following information):
Linux

Rerun version
0.18
