Hi folks, I have setup a virtual machine (VirtualBox) to have my real account trading with IB separated from other tasks. The strange thing is that AB runs in the virtual machine much faster than on the native hardware (opposite to my expectation that usually virtual machines have a performance penalty), but I have no idea why there is this huge difference.
Configuration: Native machine: Pentium 4, 2.6GHz, 1.5GB RAM, Windows XP SP3 + usual tools like antivirus, firewall etc. VirtualBox: 512MB RAM, Windows 2000 SP2, naked installation AmiBroker directory was copied 1:1 from native machine to virtual machine, I checked that all preferences are the same. Benchmark: Backtesting on Russell 1000 watchlist native machine: 32s virtual machine: 20s Wow! It looks like something on the native machine is drastically reducing the speed of AB, but I have no clue about the root cause. Did somebody observe the same? Any ideas? Thanks in advance and best regards, Markus
