JMeter：寻找有意义的 2 层架构

Question

For a project, I need to build two client-server-architecture prototypes (2-tier and 3-tier). In a second step I want to test them in terms of performance & scalability with JMeter. In a third step I want to compare the performance of both and give recommendations on the architecture.

I have already built a 3-tier application, which looks like this:

What I had in mind was to build a 2-tier application, which looks like this:

But then I realized that I cannot compare them properly. Since there is no possibility to start a function with a HTTP-request in the 2-tier-architecture.

My question now, what would a meaningful implementation of a 2-tier-prototype look like? So that I can make a fair comparison of both. and if I could use Java that would be great too.

I'm very inexperienced, so I am happy with any input!

Answer 1

In general these 2 implementations look like 2 separate products so comparing their performance is not something you should be doing.

Whatever.

Your "Presentation" statement for the 2-tier architecture doesn't tell the full story:

• if it's some form of a thin client - then you can use JMeter for simulating load onto "Controller" by impersonating real users, check out How to Do Desktop Performance Testing for more details

• if the whole "Client" is a standalone application which just communicates with the database you can:

  • use a profiler tool to ensure that your "Client" is doing its best in terms of algorithms efficiency , absence of memory leaks , etc.
  • the database can be load tested separately using the aforementioned JMeter

• separate functions or larger code blocks can be tested for concurrency using microbenchmark frameworks like jmh
