The memory usage graph in on https://data.syncthing.net/ shows a sharp increase lately, possibly together with v1.3.0. The increase is significant: From ~80MB to ~110MB. My instance reports 353MB used, which feels like more than before (unfortunately I don’t know for sure). Looking at a heap profile accounting for 140MB in total, ~130MB of that is used by goleveldb. My assumption is that the large blocks change is the reason for this memory increase. And now having written this I had another look at the PR in question, and given the increase cache and write buffer this seems sensible. So actually I don’t have a question anymore - I still think it’s worth posting, as it’s nice that the effect was well captured by usage reporting
PS: The corrected block reporting is also already showing in the transfer graph.
