Solution 1

Execution time is dependent on data sizes and indexes defined on your tables. Both Oracle and SqlServer are highly optimized database engines and they should operate in the same league for your record numbers and hardware you are using.

If they are different then you must check the indexes you have defined.

the indexes given to both the tables are same.. hardware configuration is slightly different .
