Different memory usage display in windows Task Manager and tasklist -

i tried migrate redis 2.4.6 2.8.19. run redis using 460 mb db file, found this:

>> tasklist | sort .... pycharm.exe                    344 console                    1    501,860 k python.exe                    3544 console                    1    206,944 k pythonw.exe                   1348 console                    1      7,856 k pythonw.exe                   6080 console                    1     24,852 k qvodwebservice.exe            5392 console                    1        208 k redis-server.exe              2512 console                    1  1,943,156 k regsrvc.exe                   2540 services                   0        352 k rundll32.exe                  1864 console                    1        636 k .... 

and windows task manager:

as u can see, there huge difference in memory usage redis-server.

anyone has idea why happening??

in taskmanager choose column "memory - working set"

by default displays "memory - private working set"
