Your conclusions match my own David. I started out in a very  similar way, trying to run as many browsers as I could and always wanting more computer power. These days I’d be pretty happy with just a single mid range computer with a 6-8 core processor that can run 6 reactors at the same time comfortably overnight 🙂

In a nutshell:

1. Use Chrome

2. Run EA studio on seperate browsers not seperate tabs (Again this is shown in Petkos courses)

3. Keep the Tabs visible

Kalin can I ask how many EA studio instances you are wanting run at a time? Also what is your computer processor and ram are you running (Nothing extravagant needed for EA studio in my personal opinion, just checking you are running an optimal number of EA studio instances for your hardware).
