I actually posted this question yesterday. I'm here to ask you guys again after testing.
↓↓↓First of all, please see my question↓↓↓
My customers told me that the access speed is really slow markedly!
[Circumstances] Everything is OK, every packet flows well. However, now I have focused on the speed... That is, connection is ok
[Issues] Whenever I connect or access the web servers, the access speed markedly slow. (It took for 10~20 seconds until web page has completed.)
However, it is fast sometimes... That is, slow, fast, slow, fast --- continuous
[The data] First, please see the below network structure. [The things that I want to know] As you can see the data, the structure is not complicated. To tell the truth, I don't know what device is the problem. and I also don't know what can I see in order to fix it?
I just want to know whether device's problem. If so, how can I control it.
I'll let you know how I test after posting this question yesterday. ( [L4, F/W]How can I deal with SPEED? ) <-- Yesterday question I posted.
- I captured packets with wireshark. As you can see the below capture, it showed Retransmission message. However, the frequency was very low.
I assume that it is common situation that only one retransmission is showed.
For me, the speed is extremely normal. But my two customers among them told its speed was really low...
- You know, on the google chrome, we can measure speed using F12 button. my customer captured this picture. (DNS lookup issue..?)
What should I do..? I really want to get an advice..! Could you give me an advice? Regards, SK
