When i again and again rapidly hit the db.then it’s performance become bottleneck .What to do?

It sounds like you should be caching some results. In a high load application, caching even for a few seconds can have a big impact on performance. There are a myriad of cache solutions out there; if this is a web app, the inbuilt http-context .Cache should be fine (.NET 4.0 adds MemoryCache to do the same more conveniently in non-web applications).

Re loading the data; you mention ORM – in our experience here, we find most ORMs indeed are a bottleneck for “hot” code paths – a subject I’m talking on in a few hours as it happens. Because we faced this problem, we wrote an intentionally simple but really really fast micro-ORM, dapper-dot-net. It isn’t as feature rich as some full ORMs, but if you are trying to load data quick for display, it is ideal.

The other thing, of course, is to look at your query and improve the performance. Look in particular at the logical IO reads, and where they are coming from. It could well be that an extra index or a little denormalization could make a really big difference to your query performance.
