This is a very subjective question for now. There could be numerous of reasons why the database is not responding well

You should start by narowwing down the possibilities.

Start with identifying the queries/objects, in database that can be the cause of this delay. I assume you have a front end app that basically uses this database. If so, try to find the forms/interfaces on that app which are taking longer than usual. Then analyze the database objects including tables and stored procedure or sql queries being used to query the relevant tables.

You can use Sql profiler to identify the sql batches that are taking time. Then you can use Query Execution plans in Sql Server Management Studio to help you give a more detailed picture of exactly what could be taking time in each query.

But even before you get into this stuff, try to see if your sql server is responding? This can checked by trying to connect to the concerned sql server using a sql server management studio on a different machine.

if not, probably some network latency may be causing the delay.

Let me know if you need more help.

You can use Sql Server Index Tuning Wizard from within the Sql Server Management Studio

It will suggests what indexes can be created. You can then create those indexes
