Running on a decent server (nothing super fast, but a 2 processor Celeron), I can see 3 seconds for that to come up, and close to 100% cpu.
Running on an Atom processor with 4 cores, I can see it takes 4-5 seconds and it consumes 1-2 cores with high percentages during that time.
So, that begs the question, what is the slow part of that process, is there anything I can do to make it faster? It's strange to me that it's that darn slow to paint the screen, plenty of other apps respond very quickly.
Heck, even Webmin does. If I click on the Webmin tab, it comes up fast. When I click back on Virtualmin, dog slow.
