在Windows中,我可以通过调用GetProcessMemoryInfo获取峰值内存使用情况

function TProcess.Peek: Cardinal;
var
  PMC: PPROCESS_MEMORY_COUNTERS;
  PMCSize: Cardinal;
begin
  PMCSize := SizeOf(PROCESS_MEMORY_COUNTERS);
  GetMem(PMC, PMCSize);
  try
    PMC^.cb := PMCSize;
    if GetProcessMemoryInfo(FHandle, PMC, PMCSize) then
      Exit(PMC^.PeakWorkingSetSize)
    else
      Exit(0);
  finally
    FreeMem(PMC);
  end;
end;

什么是 Mac OS 相当于执行此操作?

最佳答案

您可以像这样使用 /usr/bin/time -l <cmd>:

/usr/bin/time -l sleep 3
        3.00 real         0.00 user         0.00 sys
    552960  maximum resident set size                  <--- this one (in bytes)
         0  average shared memory size
         0  average unshared data size
         0  average unshared stack size
       144  page reclaims
         0  page faults
         0  swaps
         0  block input operations
         0  block output operations
         0  messages sent
         0  messages received
         0  signals received
         0  voluntary context switches
         2  involuntary context switches
