As per version 18.104.22.168.6 Workstation default RAM is 1024 MB. In my experience it always becomes unusable after a few Tor Browser tabs are open, even with XFCE.
I know this was already addressed some 4 years ago:
But still, average computer power has increased since then, and 1GB of RAM for a Workstation is really limited. I know it’s very easy to add RAM, but wouldn’t a default 2GB RAM render the experience more user-friendly? Especially for new users who may think that Whonix is buggy when it eventually crashes under a very reasonable workload.
