A RamDisk Experiment on old Recycled Hardware with a new HDD.
I am going to test NC 25 on an I5 notebook that has 4 GBâs of ram currently running NC 25.
If it turns out ok I will modify my backup test unit. I5 NC server as well.
Folder/User stats synced files from windows.
166 GB
166 GB
3,117 Files, 300 Folders
My project details for NC install/setup.
My Benchmark/Current speed on I5 8 GB 2 TB 7200 rpm. is ~1 second per file/ per new file when Syncing with a NC client once there are a lot of files in the NC Server. Will have to power it up and look at the bash history to find what I have tried so far if needed.
I will also share the QB64 BASIC code I create to test basic file performance in Hz on a normal HDD and of the RamDisk.
If tests results are good I may also add a ThinLinc remote access server to the experiment as well.
Continuing the discussion from Change favico.ico or color on Nextcloud Support forum website:
I have tested this Ramdisk setup with Plex TV serverâs Transcode cache folder, it worked very well increasing the number of streams playing and with very low CPU usage once the streams where running.
Playback Results:
Chrome on Win 11 tied up the CPU and also was trying to save the streamed data by the looks on the resource monitor.
4 tabs playing Videos with 100% CPU.
FireFox was much better, less CPU with more tabs open with video playing.
7 tabs playing Videos With 50% CPU.
The RAM disk setup I used to have a folder at /mnt/ramdisk used by Plex.
as root
mount -o size=4G,uid=1000 -t tmpfs tmpfs /mnt/ramdisk
As root.
nano /etc/fstab
As root add line fstab at under the last line.
Will try first line on test system.
none /mnt/ramdisk tmpfs size=4G,uid=1000 0 0
Then during each boot a new, empty ram disk will be mounted at /mnt/ramdisk for files discarded during shutdown.
I will also make a snapshot of my working current test install.
I will also use a YaCy Search Engine in Webportal mode for research.
Yacy now running and crawling, my QB64 webserver console also.
I have to try a patch from SUSE Linux for iotop in Ubuntu.
I will edit this post as I add ideaâs, experimentâs, so bookmark it otherwise it gets spread out down the ladder too far and also I have a record of what works.

I tried to repeat test but it was normalâŠ
I then used a bigger file because 806 GB was nothing exciting and happen to fast to capture any data onâŠ

win client end copy to sync area local HDD not SSD..
It started at 8.1 mbps upload to NC for some time.
I waited a bit then started clicking window for a clue but it eventually finished.
tested with SSH 806 GB in 9 seconds. upload to mirror 90 mb/s...upload non mirror 94 mb/s
Had to use win 11 iso........The clent/server did not repeat the fault even though I tested again..
806 GB sync transfer was not really exciting! or long enough to capture any data..
Old hardware specs my start or beginning with installing NC 12âŠ

Did a http test NC zip output of a folder 32 GB
It did slow down to 5.5 mb/s for awhileâŠ
50 mb/s most of the time between NC notebook HDD 5400 rpm and notebook HDD 5400
Did test of smaller files but not large enough. 1GB
