I have 8 GB RAM on my 2010 MacBook Pro. With Vagrant running, I frequently get under 300 MB of available RAM. Do I need 16 GB?<p>How much do you have and do you think you need more?
It depends on my system. Both my work MacBook Pro and personal MacBook Air have 8GB of RAM. There have been times where I've been 10GB in to swap, and the performance of the system makes me think I'm actively paging.<p>However, for most cases on my work/personal laptop the 8GB of RAM is plenty.<p>On my desktop PC, however, I have 12GB of RAM. I use this primarily for gaming, and I have definitely used 8+ GB on this box. The one time, admittedly, Windows Update was using about 9GB of RAM for no reason. But I have had games get up above 3GB in usage.<p>Also, are you sure your RAM is unavailable and not just used for disk cache or something?
Are you sure you need so much memory allocated to VMs? Worth mentioning is this blurb from Vagrant's old docs (<a href="http://docs-v1.vagrantup.com/v1/docs/base_boxes.html" rel="nofollow">http://docs-v1.vagrantup.com/v1/docs/base_boxes.html</a>):<p><i>Make sure the default memory allocation is not too high. Most people don’t want to download a box to find it using 1 GB of RAM. We typically set it at 360 MB to start, since that is the size of most small slices. </i>
I use 8gb on my mid 2010 MacBook Pro and find that it needs to be rebooted every so often to clear the memory. Since Lion OS X likes to hog all the RAM for some reason.
16GB - the maximum supported on my current hardware. Ideally I'd like 32GB.<p>I develop SharePoint solutions on a two-VM configuration locally (DC - 1GB, and app server - 8GB), both off a second drive (SSD). RAM utilisation are always ~90%.<p>Note: When the VMs are off, it hovers around 6GB usage. Each instances of Visual Studio 2012 I run adds an extra 500MB - 1GB to overall usage.
I tend to use most of my RAM and I have 16GB. I tend to do a lot of dataset/number crunching and have a few different services running at once.<p>I tend to see that as an extreme case though. For everyday web dev 8GB seems more than sufficient. I wouldn't say it's a requirement, but if you can opt for it you might as well. RAM is cheap.
I have 4 GB on my macbook air that I use for traveling, web surfing and hacking various side projects and never run into problems. I have 16 GB on my 'big' laptop that I use for serious work doing data transformation and analysis and I often wish I had 32 GB.
4 GB on my Macbook Air. It's more than enough usually, but today I was running my 512 MB Vagrant VM and many Python processes running (workers), which consumed about ~3 GB of memory alone and helped bring my laptop to a crawl. So having maybe 6 GB would be great.
12 but shooting at 32 on the next build (top of the current mobo).<p>You can never have enough RAM as a developer. I just hate closing any kinds of applications and try to restart only on patch Tuesday ...<p>And with RAM so cheap there is no excuse not to max it to what your MB supports.
WTF you do with your RAM?, What you used to do when there were not machine with more that 4GB?, I've a machine with 4GB ram and I feel me in the heaven, most of the time I'm under 2GB usage.., using Ubuntu 12.04 here
