Best way to stress test a website

Question

This may be the wrong question to ask but  what s the best way to replicate a large load on an asp net web application  Is there an easy way to simulate many requests on particular pages  Or is the best thing to use a profiler to track a single request and then work out from that if the performance is ok   It would be good to know how well a web app works with a server spec  I d like to be able to simulate heavy traffic on my testing server so that I can work out if the production server is good enough  specifically with iis asp net not db performance

My suggestion is for you to do some automated tests first  Use selenium for it   Then deploy selenium grid to test in multiple computers at the same time   Although Selenium as an automated test tool will run quite fast  making a mini stress test  If you put the same automation running on a couple of computers on your network at the same time you ll be able to see how it behaves   If you want to record response timings  they have a cool api you can use to write some scripts to run your automations   Edit  Selenium is quite easy to use  and it does asserts to page contents if you want to test the contents  It also copies your movement through the page if you wish  this would be my suggestion  just navigate the page a lot  and then save it for automation  Avoid putting asserts so selenium might run faster

We tried a few applications  both trials of commercial products and freely available ones   Ultimately  it was the trial edition of the Team Test Load Agent software that we tried   It definitely works great and is fairly simple to use   In the long run  it bolstered our argument to move to Team Foundation Server and equip all parts of the department with the appropriate tooling   The obvious downside  however  is the price

Another tool I like is Open STA  http   opensta org   It is mainly focused on the performance testing and it is free   UPDATE 2018   Since the answer is quite old  the OpenSTA project seems not very active  however the tool is still available  but now there are two other tool I would also recommends    Gatling  Load test as code  NeoLoad  The Load Testing Platform    In my opinion Gatling seems better as there is no limitation and they also provide commercial Enterprise solution and fit with continuous integration tools like Jenkins   NeoLoad in the contrary have a free version but limited to 50 user  that can be enough for some cases   The full comparison of features is here

JMeter would be one such tool  Can be a bit hard to learn and configure  but it s usually worth it

The ab  apache bench  tool allows you to send many requests to a single page and you specify how many clients you want to be used and how many concurrent connection you want   This may be the first step when developing a site  Just test some pages with a specific load  This way of benchmarking may have some problem  like caching being over used   Later you may want a tool that simulate some concrete traffic and not for a single page  I don t have a refence handy on such tool yet

Maybe grinder will help  You can simulate concurrent request by threads and lightweight processes or distribute test over several machines  I m using it extensively with success every time

I have used WebLOAD for this kind of project  It s easy to create scripts  and it has built in support for monitoring ASP NET stats
