- Hello, It’s Tony Fortunato from the Technology Firm In this presentation we will be comparing the differences between various protocols I am using my popular User Group and Throughput class format where we take a baselining example and have you steer me through what information you need. Enjoy
- I find more and more customers asking 2 basic questions; Why is the newer app slower than the old one We can use various applications/protocols for the same task, so which one is better How come app X suddenly runs slow, or times-out? Since I am analyzing the application behavior, 2 laptops are fine. If performance was the issue, then I would make sure I had similar hardware. Making sure you have a plan and some kind of naming convention sounds so trivial, but makes the exercise go much quicker and instills some consistency
- I always document the test/lab environment in case I come back at a later date and need to perform more tests Having the trace files helps since I have the MAC addresses of the PC’s in case I don’t document the computer names – like this time
- Many times computers may be communicating with servers, broadcasting or chatting via remote desktop control applications. The very basic host filter helps capture only the data between the 2 stations. Since I am on a switch I do not need to put my ip into the filter, just the destination IP address
- Learning how to automate, or what to type in for your transfers helps make your testing go more quicker and consistently I am always surprised how many people I impress by typing the url into the Start->Run dialogue box
- As you start digging into applications and protocols you will find that there are many setting that can be changed affect your performance
- Much like my earlier comment, I prefer to use the command prompt for better control and many times the command prompt will show error or status messages that the GUI will not
- Anyone who has been through this process before, can attest to the fact that things can quickly get out of control and chew up most of your day --- or life So I will start with the basics – cleaning up the trace file and using the popular Statistics->Summary screen
- I try to use this screen as much as possible since I can easily identify which port number is used for the transfer. This is especially handy with the transfer is embedded within an application or proprietary After your display filter is applied, you will notice in many of the Wireshark screens, will have radio buttons or references to the displayed results as well as the entire trace
- This is an example of what I just mentioned, this screen has a Captured and Displayed column headers For our purposes, I will use the Displayed column from all 2 traces. There are ways to do this from the command prompt using tshark and the –z option, but I want to keep this as straight forward as possible
- Anyone who knows me, knows I always try generate a graph. I find a graph easily highlights the highs and lows for technical and non technical staff This chart only took a few minutes to put together
- Now I will try something different. I am asking the Lovemytool audience to let me know what the next presentation should cover. I can easily go off an a tangent and give you pages of information that may not help you. I have created an email address for those of you who who prefer to email me your feedback. Let me know what you would like to see me do next
- I am looking forward to your feedback for my next series of slides and hopes this helps you along the way. Enjoy
