For me it takes ~2.7GB initially and 3.5GB after the first reload. In<br>
the past I've seen it get all the way up to 9GB so there may be some<br>
memory leakage.<br>
<br>
I have 40GB of ram in my laptop, so I don't notice this much. I<br>
highly recommend investing in more memory if it's within your<br>
financial means. The productivity boon of being able to use GHCi on<br>
large projects, or run multiple concurrent docker containers or VMs,<br>
is huge.<br>
<br>
A bit off topic, but sometimes folks are surprised that I spend<br>
hundreds of dollars on keyboards like the kinesis advantage 2 (which<br>
is fantastic, btw) or the <a href="http://keyboard.io" rel="noreferrer" target="_blank">keyboard.io</a> (really nice too!). My answer<br>
is that if I'm using some equipment many hours per day, the cost<br>
amortizes out. I ask myself "Would I pay 3 cents to use this keyboard<br>
for an hour?", in the case of those keyboards, my answer is an<br>
emphatic YES! I apply similar reasoning to my main computer hardware,<br>
though people are used to that being $$$ vs the surprise of $350<br>
keyboards.<br>
