There was a change in go 1.16 <https://golang.org/doc/go1.16#runtime> which could affect this, so I suggest you try the latest go. Previously, go just marked the pages as "can be freed when required" - but the OS would not actually free them until under memory pressure. Now it tells the OS to free them immediately. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
