Am i have to tune my db?

Question

Friends,
OS: RHEL AS 3
DB: 9.2.0.4
Suddenly our users are telling that, there is a little bit slow in our applications.
we are using oracle forms and reports for the front end.
i just used the below query to find the things.
Am i have to do any performance tuning according to the below values?
if yes, what is the first step i have to do?
I have not done any database tuning before this.
kindly advice me.

VPS,
Your output doesn't tell anything.
You are limiting your output to a particular category of statistics.
Also all v$ statistics are cumulative since the last boot.
What you need to do is to install statspack, if you already didn't do so,
from $ORACLE_HOME/rdbms/admin/spcreate.sql
Documentation about statspack is in $ORACLE_HOME/rdbms/admin/spdoc.txt
Please note 9.2.0.4 is desupported.
