Stress test RAM

shared requirements for all kinds of resources (CPU RAM I/O TX/RX)

    # debian/ubuntu
    apt install -y stress iperf3 hdparm

    # slackware
    slackpkg update
    slackpkg install screen-4 utempter
    slackpkg install rsync cyrus-sasl curl lz4 zstd xxHash nghttp2 brotli
    slackpkg install kernel-headers patch gcc-11 automake autoconf-2 binutils make guile gc
    wget https://github.com/sbopkg/sbopkg/releases/download/0.38.2/sbopkg-0.38.2-noarch-1_wsr.tgz
    installpkg --terse sbopkg-0.38.2-noarch-1_wsr.tgz
    sbopkg -r
    sbopkg -i stress
    sbopkg -i perf3
    slackpkg install hdparm

and proceed

(assuming tmem)

lsmod | grep tmem

screen -S ram
mkdir -p ram/
mount -t tmpfs -o size=7168M tmpfs ram/
dd if=/dev/zero of=ram/lala bs=1

watch free -m

it will then shrink back by itself

umount ram/
rmdir ram/
