Q: What are the recommended virtual machine RAM and CPU specs for Unidesk for the Management Appliance and CachePoints?

A: Customers will occasionally change the CPU and RAM settings for their Unidesk appliances. We recommend leaving these at the values defined in the original OVF files: 2 CPUs and 2GB RAM. But it's perfectly legal for them to change them.

We've never seen a particular performance improvement from increasing those specs. The main reason is that each CP will only perform up to 4 tasks in parallel, so even with many desktops on a single CP, we'll only touch 4 at a time. As each edit finishes, we'll swap in another desktop to begin its edit. The 2 CPUs and 2GB of RAM are normally well more than enough to support that.

That said, you can certainly increase the number of CPUs to 4 safely, just to see if it changes anything. I wouldn't have you change the RAM, because you can't resize the swap partition in Linux. That's not a fatal limitation, but it does mean that any possible performance improvements are more murky.

As of 2.0, we at least smoke-test multiple CPUs and RAM settings on CachePoints periodically (not on every release), and they work and don't cause performance problems. It's perfectly OK to allow customers to increase RAM and CPUs if they think it might help. Generally it won't, but it hurts nothing to try.
