I check my WebApp with dotTrace to understand some performance issues. In the example below, 67,3% of the time is used by KernelBase. Do you have any idea why this process is time consuming and how to solution or understand it ? I dont known if the issue is with IIS, resources (IO, CPU, RAM) or ASP.net.

  • You're looking at the "hot path", which is only useful if your bottleneck is on it. More likely, it is not. There's a method that's not only simple and free, but more effective.

  • It is possible this time to be compile time ? Its looks like compile... – Aristos Feb 03 '15 at 14:11
  • Compile ? JIT compilation ? – Jerome Feb 03 '15 at 16:15
