Everyone said linq very slow performance how reduce that problem ???

Answer 1

Tha answer is,when the problem is a performace, not use a linq. Because the linq is a new generally comon query language over many different sources of data. But not the fastest in all cases. So, for getting a maximum performance use another access to your data. For example - to access array is faster the classic for loop. For large databases a pure sql over remote sql server (because over there on remote sql server would be the performance,..) and so on..

Answer 2

LINQ is not slow. There are many LINQ providers, maybe they use database providers and they do it wrong?
