Dear All,
I have a client for mysql which give me the time it took to query but now is very doubtful. I have 2 machines on the same networking accessing the same database one is showing 360ms and the other is showing 5469ms ? Thus I am very confuse where can I verify which is the exact time ? Thanks.

Where do you get these times in ms ?

It well may be there are some network differences or some time is spent on the client library.

You can see the time in MySQL Server slow query logs if you enable them, unfortunately by default it is 1sec resolution unless you apply our microsecond resolution patches.

Dear Peter,
Let me explain I am using mysqlyog client. The problem is that both the pc's are on the same network. The best of all the pc with less specification gives a better than a pc which have a higher specification so this is where I am very doubtful ? Is there any other method where I can confirm on this ? Thanks.

Oh, That is a typo

Run it from mysql command line to see the times first.

The fact your boxes are on the same network do not guaranty they have the same connection speed - there can be packet loss and other issues.

Dear Peter,
The server which I am trying to connect is on a remote location. So how can I connect using command line ? Another thing is that when I run on a command line will I be able to see the time it took ? Thanks.

You really need to do some manual reading.

Dear Peter,
So beside connection speed what else you think can be causing my time to be different ? Ok I have gone through the manual. The problem the moment I open mysql command line client it ask for password. So I tried something like this

C:\Documents and Settings\Administrator>mysql remoteIP I typed
'mysql' is not recognized as an internal or extern
operable program or batch file.

Any help please ? I am new to all this. Thanks.
