Hi All,
I have a list of having more than 2000 records. I want to get sublist of the same. But it is very slow. Is there any other way I can get the sublist of the large list.
Please help.

Thanks in advance.

Please TellTheDetails. Is this list ordered already? What are these "records"? Are these objects too complex? What is the filter for this sublist?

2000 is not a large list. It should take a few μs to get a sublist.

Please show us how you create this sub list. If that's slow then perhaps you're doing it in a less efficient way.

There are many ways. If the way you're using is to slow, then you should use a different way.
