Tagging subscribers to this area: @dotnet/gc Issue DetailsI'm seeing with SIP the heap size can increase noticeably because we don't compact the SIP regions, for workload that rarely ever does blocking gen2s. so I'm making these not on by default but can be turned on with the GCEnableSpecialRegions config.

there are a few methods that are currently compiled for both segments and regions but are only used for segments so made those only compiled for segments. |

do we want to document this, or is it only for certain workloads we know would benefit from SIP?

for now it's just special workloads so I thought I'd leave it as an experimental thing (so not supported in runtimeconfig). we can decide whether to support in runtimeconmfig in the next release when we have experimented with it more. does that sound reasonable?
