I know this doesn't help, but I am running with -J-Xmx2048m on a 16GB Lenovo Laptop with 16G and a Core i7-7500 without problems. Even with a project group with approx. 25 (large) open project, startup usually finishes in about 10 seconds. The "Opening Projects" plus Background scanning then takes about 40-60 seconds. I am using OpenJDK 11 though How many projects does your project list contain?
