creating multiple indexes on same column will effect performance?
 for example:

index1 : column1, column2, column3
index2: column1
index3: column2,
index4: column3
index5: column1,column2

The sole purpose of indexes is to affect performance.

However, if you have index1, there is no point in having index2 or index5.
