Info for all jealous and knowledgeable who claim my grid and 162 sim are slow. (user01) I did a test with an old pentium 4 Intl core 2 quad 3.2GHz, 8GB memory card 6 years out of life no more driver, "1GBite" internet. I'm going to my sim house market 60000 prim hard test. No difference to my PC i7 core 8, 4.3GHz, 32GB memory new Graficcard Gigabite. All work fine and stable fast. :-D
If my grid is slow for you, it may be time to think about the 50MBite internet and your old PC. That could be helpful. ;-)
