I have found some valuable facts regarding comparison between PHP and ASP.Net. I hope this will help a lot deciding between what to use for a professional web application development. http://naspinski.net/post/AspNet-vs-php--speed-comparison.aspx Looking forward to other people feedback.
It is like saying: Which car is faster: Honda Civic or Toyota Corolla on a road with posted speed limit of 100 km/hr ? They are both good. Pick one, live happily ever after.
Sorry, peter... most of the toyota cars are called back...kidding.. Technically, depends how anyone code the application and nature of the application. The difference will be infinitesimal.
Before every1 says that asp is better, i just want to ask "Why all wolrd biggest sites are php?" p.s i think asp is better but i cant find answer on question above :d
The speed of the app is going to rely on so many things - server processor speed, disk speeds, database server connection (local or remote), local caching etc that either script language is going to perform well enough given similar variables. Just look at some of the biggest sites out there. facebook - php, microsoft - aspx there is no perceptible difference...
1. Because PHP is *not* Microsoft. 2. Because PHP was a mature product before there was asp.net 3. Because there is no reason to learn/convert from a huge investment in PHP 4. Because number 1, again
