Marcel Reutegger commented on OAK-969:
--------------------------------------
Turns out this may get even worse. Now I'm looking at a dump where the cache is
set to 64MB and the retained set is 300MB.
Some stats:
- The dump contains 21'411 Segment instances.
- The smallest Segments have a retained size of 336 bytes and a ByteBuffer
limit of 4.
- The largest Segment has a retained size of 90k and a ByteBuffer limit of
65600.
- The average retained size of a Segment is 14k
This is the main contributor to the OOME reported in OAK-968.
> More accurate cache weight for Segment

> Issue Type: Improvement
> Components: core
> Reporter: Marcel Reutegger
> Priority: Minor

> The cache weight for the Segment currently only takes the size of the
> ByteBuffer into account. A heap dump showed that with a cache size of 100MB
> the actual memory usage was roughly 170MB.
