2% is a better default as I normally observe apps spent more like 2% in Server GC instead of 5%. I'm still doing some analysis on the effect but for the preview it's better to (hopefully) get data on 2% than 5%. in the local testing with GCPerfSim (only SOH allocations with low surv rate) I'm seeing a small percentage of throughput inc with a bigger percentage of max memory usage. with asp.net benchmarks I'm not seeing nearly as big a difference.
it can be changed via either the
GCDTargetTCPenv var or theSystem.GC.DTargetTCPruntime config.
