IRamDisk

Iramdisk 3.6.12

I code on a late 2011 Mac Mini with 8 GB RAM and a 256 GB SSD. This machine is a ton faster than my old MacBook Air was. Compilation still takes time, but it seems that iRamDisk helps a bit.

Lately I wondered if I could cut down the 30s compilation time (3mins with a clean build folder) if I had a Mac Pro, or MacBook Pro, or iMac, or whatever next tier device. Faster cores, more cores, doesn’t matter. But buying a Mac for $3k is out of question at the moment. So I’ve been looking for other tricks.

Download the latest version of iRamDisk for Mac free. IRamDisk uses a part of your RAM to create a new volume shown as an ordinary drive that can be mounted and used independently in your Finder. IRamDisk uses a block of memory to creates a virtual RAM Volume displayed like real disk by Mac OS X. Data into memory are written and read more quickly than the system disk. Move the temporary files into RamDisk may reduce the delay of a process (compilation, image processing.). Dj mixer express. IRamDisk is based on Unix commands.

The only thing that’s faster than a SSD is RAM. That’s when I found the app iRamDisk. It offers an option to move the derived data folder to a virtual disk in RAM. It seems I can reduce the clean build time from 3mins to 2mins with that. Xcode needs about 1.5GB derived data for the Word Counter – at least that’s how big I had to make the RAM disk to not get filled quickly. The overall memory pressure is a bit higher, the Mac is using swap more, but compilation becomes faster at last.

There’s a downside, too: after every reboot the RAM disk is empty, so Xcode has to index the project again and compile fresh at least once a day. Depending on your usage this can be annoying or not be a problem at all.

You can download a trial from the website or buy it for $19.99 on the Mac App Store.
