Production Fine Tuning Questions

 Hi,

 I am having three questions on this database tuning front.

 Question 1:

    I am accessing a table12 (which holds 4 million of records) which resides in a tablespace and this tablespace1 contains 10 data files. And each datafile of the size is 10 GB.

    While accessing the table data from the above tablespace1 takes time to respond to the user.

    Now i have created a separate tablespace which was pointed to the above table12. Now the querying was faster.

    My question - Having 10 datafile into one tablespace will affect my query performance?

                            (or) What is the best practice for this one?

  Question 2:

   Running two instances in the same LPAR will affect my performance?

Howdy, Stranger!
