I have a table which has lot of inserts, is it a good database design to create indexes on that table? Insert’s are slower on tables which have indexes, justify it?or Why do page splitting happen?


All indexing fundamentals in database use “B-tree” fundamental. Now whenever there is new data inserted or deleted the tree tries to become unbalance.
Creates a new page to balance the tree. 
Shuffle and move the data to pages.
So if your table is having heavy inserts that means it’s transactional, then you can visualize the amount of splits it will be doing. This will not only increase insert time but will also upset the end-user who is sitting on the screen. So when you forecast that a table has lot of inserts it’s not a good idea to create indexes.
