But this 4 8GB is dead slow at times browsing the web. Added a metal case with fan now to prevent it from throtling on over-temperature so now its hovers around temp=40.9'C temp=41.3'C temp=40.4' ... Just cut and paste Has a 4 TB Toshiba harddisc connected to it, some RTL-SDR stick, A huawei 4G stick so I have internet on it, a HDMI monitor, and for all the other USB stuff a Sitecom USB hub, a Logitech wireless keyboard... and that IR FLIR camera on GPIO. raspberrypi: ~ # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/root 30421240 27643352 1432704 96% / devtmpfs 3879380 0 3879380 0% /dev tmpfs 4044244 0 4044244 0% /dev/shm tmpfs 1617700 1336 1616364 1% /run tmpfs 5120 4 5116 1% /run/lock /dev/mmcblk0p1 258095 50413 207682 20% /boot tmpfs 808848 24 808824 1% /run/user/1000 /dev/sda2 3844420600 2863079020 785980916 79% /mnt/sda2 raspberrypi: ~ # top top - 07:27:40 up 1 day, 22:12, 11 users, load average: 0.64, 0.66, 0.97 Tasks: 221 total, 1 running, 220 sleeping, 0 stopped, 0 zombie %Cpu(s): 4.8 us, 4.3 sy, 0.0 ni, 90.8 id, 0.1 wa, 0.0 hi, 0.1 si, 0.0 st MiB Mem : 7898.9 total, 6529.0 free, 727.2 used, 642.7 buff/cache MiB Swap: 100.0 total, 100.0 free, 0.0 used. 6853.9 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1105 root 19 -1 195056 77668 56360 S 10.2 1.0 195:49.13 Xorg 12594 root 20 0 980792 351696 161036 S 6.6 4.3 7:45.00 firefox-esr 12782 root 20 0 496732 164380 94644 S 3.9 2.0 2:14.18 Web Content 1123 root 20 0 48028 12892 8604 S 1.6 0.2 0:01.86 rxvt 1219 root 20 0 6644 4208 3832 S 1.6 0.1 37:20.43 xosview 12732 root 20 0 640868 135868 81320 S 1.3 1.7 1:02.58 WebExtensions .....
