testmem.exe is a command-line tool for testing speed of the memory access on your computer. It will just print out time and speed of consecutive writing and reading a few megabytes of memory several times.
This distribution includes:
Program itself (40KB)
Source code (for MSVC).
Please send me any comments on bugs you may find here.
Program archived (21KB)
Program + source + makefile archive
!!! Some browsers, like Netscape, will download .rar archive in text mode by
default. This results in a broken archive.
I also plan to run a small database on TestMem page with test results from
various systems. Please e-mail me
your computer's test.
Instructions: from Windows start menu, choose command prompt. Change directory
to the one where you' ve just downloaded/unpacked testmem.exe. Switch to
fullscreen mode (via alt+Enter).
Run
testmem 10 10
If there was heavy swapping during this program's run - run it again.
At this point, you can copy program's results from your console window to
clipboard (see console window's system menu|edit).
>Writing 10 MB 10 times (gives quite correct results)
