I’m writing trading software and I need every single microsecond in speed.
What can I do? I was thinking to use ngen but wikipedia tells that JIT might be even better. What can I tune? May I force it to use Xeon E5 instructions somehow? Will changing priority in Windows to highest help and if so how to run program always with highest priority? May I add this program to “trusted” so .NET will not check security etc.

I.e. I want complete list of configurations in hardware/software/.net and actions (like running ngen) which can affect and help run program faster.

    The time comes stop guessing and find where the problem(s) actually are.
    Use EQATEC free preformance analyzer to figure out your bottlenecks and fix them.

    NGEN is usefull to boost the startup time of the application , but it’s definitely not a golden key for that problem. It’s most probabble that you will fix it profiling your app.

    What about runtime optimization:

    • checkout DB accesses (if any), optimize your queries and minimize the data retrived to the amount you really need

    • look on disk access operations

    • look on CPU consuption. After profiling yoi can use Process Explorer to check CPU and Memory consuption from your application behavioural point of view

    • after profiling identify unnecessary or heavy iteration you made (if any), and make use of dictionary (just example) for O(1) access

    … and more…

    Like a literature for reading on performance can suggest definitely the monster blog of one of the greatest performance specialists in IT industry: Rico Mariani’s Performance Tidbits

    Hope this helps.
