Factors which effect our application performance

Hi all friends

I want to know, what are the major factors which effect our application performance, like hardware, software, or programming language we choose, or the coding done by a programmer, or the component we use to program? I know i may be a silly question but I wan to know what the real fact is?

The biggie is choice of algorithm. All others are (mostly) irrelevant.

A badly implemented merge sort on a "slow language" running in "slow hardware" will be much more performant than a very well implemented bubble sort on a "fast language" on "fast hardware" (for large enough data).

Avoid using INotifyPropertyChanged interface, unless it is required. If the object doesn’t change at run-time, it is better not to use this interface to save memory and CPU resources.

Add data to the end of collection (List<T>, BindingList<T>, ThreadSafeBindingList<T> etc). Otherwise, internal implementation of indexed collections will move and re-index all data starting from the newly added index.

Avoid adding data to a binding list with more than 10 000 items when the grid is sorted. Stop sorting to improve performance dapfor. com

My sig has a writeup on performance programming if you are interested.

It is not that old programmers are any smarter or code better, it is just that they have made the same stupid mistake so many times that it is second nature to fix it.
