I have a pci-e based storage working at close to 1000mb/s (Mac Pro). I do lots of GCC/make compilations. What if you want things even faster than with a pcie? Then ramdisk is your friend.
- With Regular SSD: 2 minutes and 37 seconds (on my co-worker’s machine w/Fedora)
- With my pci-e disk: 2 minutes and 35 seconds (my Mac w/Fedora)
- With Ramdisk: 1 minute and 15 seconds (my Mac w/Fedora)
So we have ~50% improvement in compilation time. For me, it’s worth the effort.
To set one up: Follow this guide
[code language='bash'] sudo mkdir /mnt/ramdisk sudo mount -t tmpfs -o size=2G tmpfs /mnt/ramdisk [/code]
To see how much of it is still available:
You might want to write an rsync script to copy folders onto the ramdisk that you want fast-access to. Ex a git repo that you compile frequently, some application binaries that you run. But obviously avoid putting data onto the disk.
