Performance information that we have to take from users

Performance information that users can provide

We can notice the system tuning is required when first we get a complaint from the users. 

When we do not have enough time to change the performance tuning objectives, we can know the performance statistics by asking few questions to the users who complains us about the performance degrade.

we can usually determine where to start looking for a problem by asking a few simple questions.

Those are..

1. ==> What do you mean by “slow response”? Is it 10 % slower than you expect it to be, or tens                 of times slower?
2. ==> When did you notice the problem? Is it recent or has it always been there?
3. ==> Do other users have the same problem? Are these users one or two individuals or a whole               group?
4. ==> If a group of users is experiencing the same problems, are they connected to the same                    local area network?
5. ==> Do the problems seem to be related to a specific transaction or application program?
6. ==> Do you notice any pattern in the problem occurrence? For example, does the problem                     occur at a specific time of day, such as during lunch hour, or is it more or less                                   continuous?
