Ages ago with CRUX, I remember William made the argument that ramdisks were no longer worth doing considering the volatility, difficulty of setup, and decreasing price of SSDs.
Recently, I was playing around with an extra VPS that I have and trying to see if it could run a Minecraft server. From what I can tell, the bottleneck must be the disk I/O. The CPU was hovering around 1.8 (on a 4 core VPS) and it was still very laggy. (Can anyone recommend a good way to confirm that that is the bottleneck?)
I’m wondering if I could make my server load from a ramdisk, and if it would speed things up. Would I need to do anything special to avoid interfering with what MineOS does or could I open up fstab and add /var/games/minecraft/server/______ to a ramdisk in there?
