When I ran Geo2Grid 1.0 on a CentOS 6 and CentOS 7 machine I got the same results of ~1.1GB. Kathy Strabala has mentioned to me that it seems to depend on what machine you are running it on. This may be something out of our control and may depend on the CPU being run on.
What operating system are you running on? Any idea what CPU(s) you are using?
Well, that's definitely very interesting, I haven't seen such differences before. I can't disagree with Kathy's observations based on the tests you have done and what I get.
I'm currently running a CentOS 7 VM. The underlying hardware is an Intel i7-6700K CPU (8 w/ Hyperthread), but I'm working on moving it to a physical system with an i7-3770K CPU (8 w/ Hyperthread) and running CentOS 7 as well. I'm looking forward now, to what I'm going to get on the physical one. I like to test things out in a VM, before I spend too much time with a physical setup.
I will say that on my end, I don't mind the large file sizes, since I don't keep them for too long. I prefer image quality over disk.
