Windows has neither /proc nor ps nor getrusage, so RSS and MAXRSS were always 0. The working set and its peak from GetProcessMemoryInfo are the closest equivalents. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Changes in private memory on Windows show up in the commit charge (PagefileUsage of GetProcessMemoryInfo) more than in the working set. The result JSON keeps it and its peak as commit_charge and peak_commit_charge. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

On Windows,
rss,maxrssand the RSS samples taken after each iteration are always 0, because there is no/proc,psorgetrusageto read them from.This reports the working set and its peak from
GetProcessMemoryInfoas RSS and MAXRSS. It also records the commit charge and its peak ascommit_chargeandpeak_commit_charge, since private allocations on Windows show up there more than in the working set.Generated with Claude Code
