I'm using HP DL360p Gen8 + Windows Server 2008 R2 for HFT trading. That means that every 10 microseconds is important for me. I do understand that if I need everything to be so fast I probably should consider using Linux. But in this post I want to compare only Windows Server 2008 R2 and Windows Server 2012.
I've found in internet couple articles that suggest how to tune Windows Server 2012 for low latency
Most part of optimizations from these articles apply only to Windows Server 2012 and can not be used on Windows Server 2008 R2.
So now I think that as I can optimize Windows Server 2012 for low latency, probaly I should upgrade? After optimizations how much faster windows server 2012 would be (ideally in microseconds :)?
