I have a simple hello world written in asp.net, php and regular html. They are being served by nginx using fastcgi for php5 and xsp (mono 2.6.7, fastcgi-mono-server2.exe 2.6.5.0). I am using a simple .NET script to make async web request. What i found was in the span of 1000ms

  • php: 250-400
  • asp: 120-140
  • html: 600-900
  • 8k png: 250-300

With a simple hello world app php is consistently 2-3x faster.
Why is this? i always thought asp.net would be faster (and php startup would be slow). But it appears per request asp is significantly slower. Now i understand i am not actually comparing execution speed since its hello word and not complex code.

What is the difference between the two backends to make this significant difference?

Here is the code i use to test the request.
