How to read server statistics?

[John Fligg]

I have a client who is telling me that the response times on their Android tablet are VERY slow.

Attached are the 2 screenshots I am using to try and isolate the problem but not sure how to read them.

Server2 shows an average response time of 0.02 seconds. Am I right in saying that the server is responding OK? I am sure I am.

Server 1 shows what I THINK is the user doing something in real time. Take the 5th line down, Browse Breed at 15:22:46 then Update patient above at 15:23:02 this indicates that it took 16 seconds to retrieve a record and return it. Surely that cannot be right?

Am I reading this correctly?

The thing is they tell me that response times from a  similar application (a competitor) are MUCH faster and almost instantaneous in the same conditions.

Both applications are using a US server and the client is resident in the US so I am confused why the response times should be so slow.

All I do know is that he is using a Samsung Galaxy tablet which is Android and I have had him switch to simulate desktop mode (non mobile) as NT6 was detecting the Android as a mobile OS.

Thanks

What is the performance like if you do the same things from your machine?
What is the performance if he accesses the pages from a wired network (ie not wifi).
In order to determine where the performance issue is, you first need to identify which part of the request is slow.

Thanks Bruce. Yes he confirms that the response time are like 15 seconds!!!!

I just logged into his account and did what he did using a Windows Touchscreen and response times are virtually instant. And that is me in the UK accessing a US server. Also I am using WiFi.

I would say it is his issue but he insists that using a competitors product the times are much faster.

The only thing he can come up with is that this is an Androind OS running on a tablet which is a bit unusual I think.

So far as I am concerned I am using the same setup as him and the only difference is I am using Windows and he is using Android. He is unable to tell me what browser he is using!!!

Hmmmmm

BTW Bruce - just for the record really, is there a way for him to have a log file saved on his machine in anyway? Is there a way to get a log file saved by the app on the server. I am sure there is.

What I am getting at is it would be nice if I could somehow get the statistics of when he pressed a button, when the server received that and sent it back and ultimately when his screen refreshed.

Being as the server and machine are 2 different things that makes it impossible to compare but if I had 2 logs to work with I might at least be able to PROVE it's his machine.

I think in this particular case it is a matter of proving to him it is down to him or I will lose the sale. He prefers my application but the response times are so slow to make it useless.

BTW I have asked him to call a  friend and have them log in on a PC perhaps. Alternatiebly I might ask him if he can give you permission to log in quickly and test your end to see the response times.


Thanks

Sorry - just realised ....

Is this the fact that it is Android that is causing the problem? Let me explain ...

This is a Samsung Galaxy tablet that is running Android. Because of the way NT6 is working it is thinking that because it is Android it runs in mobile mode. So I have instructed the client to use the ?mobile=0 switch to force it into full screen mode.

Could there be any way that this is affecting performance? Maybe the other company have found a way round this or something. All I know is that they are not using NT6.

Quite frankly that is the ONLY explanation i can now come up with.

Thanks
