The value of time-out was 5. "Reply size" -- this is useful when testing change which are geared towards reducing the base payload of your application. It's important to note that it is designed as an interface to httperf and not a full feature automation suite. :), test tools are one of those things where you really need the source code to get what you want. Obviously, I'm not implementing "/foo", "/bar" and "/bah" as AJAX on my site, but you get the idea. The siege tool allows to simulate requests from a specified number of users, making follow-on requests only after users received a response. Edit: Just in case you're curious, we simulate 3500 requests per second on a low-power, inexpensive, ultra-small-form-factor Optiplex 330. So if I'm testing url/staticfile.jpg, is the server just sending "200 ok yeah this endpoint exists" or is it actually crunching/serving the data? Graph CPU and RAM consumption of the subject. httperf --server yourdomain.com --port 80 --num-conns 10 --rate 1 server:- Specifies the IP hostname of the server. sudo apt-get install httperf Example. Check out my github. When the Reply Rate is nearly equal to Request Rate then we can tell that the server is doing well. If you see non-200 HTTP responses, like this 301 example response below, then you need to ensure you have the correct –uri parameter: You can ignore the open files warning – it’s a bug in httperf. Published by Pradeesh Kumar. It worked very well for the pages which don't require cookies. Things like adding 'gzip' compression, uglifying JavaScript or 'haml', etc. httperf is a tool for measuring web server performance. It's important to note that by default httperf only tests the standard http payload of your application -- e.g. Performance Testing with Httperf, httperf is a command-line single-thread load tester developed by Hewlett-Packard Labs. Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.. Visit Stack Exchange David Mosberger from Hewlett-packard, came up with httperf for performance benchmarking a webserver. Ruby driver for httperf - automated load and performance testing - igrigorik/autoperf The three distinguishing characteristics of httperf are its robustness, which includes the ability to generate and sustain server overload, support for the HTTP/1.1 and SSL protocols, and its extensibility to new workload generators and performance measurements.". httperf is implemented in C, for keeping its performance high. The service I needed to test requires some POST parameters. This flag should probably be omitted if generating load on the same box your application is running on. On CentOS 7: do runs 3 times at different times of the day and/or seasons, again, always check for non-zero error counts, add load and stress testing to your server and application deployment checklists. Here's the command I use to generate a traffic log from Nginx's access.log: This assumes -- of course -- that your request path is in the seventh column. On the load-testing instance, install siege and httperf as your load testing tools: sudo apt-get install -y siege httperf. Generating load from an external connection can be good to test your overall network latency, but be sure your starting point connection can handle large amounts of traffic. I don't claim to be an expert in this area (AT ALL), however, here a few things I've picked up in my travels, which has made my life easier in regards to performance testing best practices. For extremely high-volume load testing, Httperf is the way to go. With "--wsesslog", the first to field is the number of connections to make, basically the same as "--num-conns" from the previous example. There are many load testing tools available today for all kinds of applications and organization. Httperf is a tool for measuring web server performance. For example, in the graph below, you’re running a load of 20 users to see that the page time does not exceed 3.5 seconds. Previous vsftpd Installation & Configuration. It provides a flexible facility for generating various HTTP workloads and for measuring server performance. It's important to note that by default httperf only tests the standard http payload of your application -- e.g. Whenever possible, generate load (i.e. Ruby, Don't performance test against production applications! http_load - multiprocessing http test client Fetch the software. Autobench runs httperf a specified number of times against a URI, increasing the number of requests per second (which I equate to -c in ab) so that the response rate or the response time can be graphed vs. requests per second. The second field is defined as "burst-to-burst user think time", which most simply means the number of times to access the URI before moving on to the next -- e.g. Googling for how to specify them led me to this gist which uses the session execution feature of httperf. httperf --server 192.168.1.2 --wsesslog 100,2,/tmp/myfile --max-piped-calls=5 --rate 10 DESCRIPTION "Connection time [ms]" -- this is the meat of the test. Autobench is a perl wrapper around httperf for automating the process of load testing a web server. In this document, I will be referring to this as the "base payload". Then you can run httperf to load test your recorded session with something like this. But while JMeter is nice, it's definitely a heavy-weight, and that's where httperf comes into the picture (http_load is also a great app, albeit without many of the features of httperf).

They aren't always hard rules and I've broken all of them out of necessity at one point or another. However unlike most such test clients, it runs in a single process, so it doesn't bog down the client machine. There are ways to configure it to load additional requests as part of the same session, which I will be covering. on 13 August 2012 The focus of httperf is not on implementing one particular benchmark but on providing a robust, high-performance tool that facilitates the construction of both micro- and macro-level benchmarks. You then need specify the log file you want to use in the place of "--uri" to tell 'httperf' what paths to use. httperf, load testing tools. Breaking down the results, I typically focus on the following rows: While my examples don't include this, using the "--hog" flag when running httperf on a host dedicated to generating load is a very good idea. Installing httperf. Much like "curl", it does not load assets (images, javascript or css) by default. It provides a flexible facility for generating various HTTP workloads and for measuring server performance. As expected – this is the bread and butter of every load tester, where you test how a system behaves with a large number of users and what is the response time received for pages under different scenarios. You set the bulk of httperf’s configuration via command-line parameters. A sample invocation for a total of 5,000 connections, each one of which should try to issue 50 requests, looks like this: The first line of output will show arguments that have been assigned their defaults because you haven’t specified them: Unlike curl-loader, httperf doesn’… This past weekend I dabbled in C++ for the first time patching httperf to use display each connection's timing when using verbose mode. It provides a flexible facility for generating various HTTP workloads and for measuring server performance. Load Testing With Log Replay. "Connection rate" -- this is mostly useful when not passing "--rate", which sends connections as fast as possible. For example, generating 100,000 connections at 100QPS from a Cable or DSL line probably isn't the best idea. in "Reply status" -- it's important to ensure that you're getting 200's when testing (or perhaps 302s if that's expected). My most recent project is cassandra-top. It also helps to assure that your load generation hardware is better than the server hardware you’re testing; e.g., I generate load with a four-core i5-750 box, and run the server on a slower, two-core i3-350 box, often only using one of the cores. Posted by Nikesh Jauhari. I've been engineering for over 20 years for companies like eBay, Netflix, Yahoo!, Apple, Amazon and startups.

For this, I performed load testing using httperf from the client system. In this document, I will be referring to this as … Httperf – web server load testing. httperf is an easy-to-use but powerful GPL2 command line (CLI) stress and load testing tool for linux. Use "--hog" any time you're generating load from a separate host and your request rate is high. I use TuCows/Hover for registering domain names. Each httperf test will consist of a session (or sessions) made up of calls spaced out at certain intervals. In more advanced usages you can create a a series of URIs to pass to emulate a single session. To do this, you need to create a connections file with all URIs you want to hit. I use Nginx, so that's what I'm going to focus on here. San Jose, San Jose International Airport, CA, Observations by a Programmer/DBA of Silicon Valley and Beyond, MySQL Database-As-A-Service Products Comparison Chart, Redhat, CentOS and Scientific Linux Releases Chart, Congrats to Cirrus on Type Certificate for SF50 Jet, SO: Changing the file descriptor size in httperf, easyengine.io: Increase "Open Files Limit", Daily Performance for Monitor Check 1000001, Always get permission from the site owner first before doing load testing. in Additionally, you have to pass --num-conns with the number of connections your want to run, a simple way to do this is --num-conns $( wc -l urls.log ). While running, it keeps track of a number of performance metrics that are summarized in the form of statistics that are printed at the end of a test run. Okay, simple enough. From this, we need to generate a file which is ASCII NUL separated which we'll call "wlog.log": Convert it to wlog.log -- replace line breaks with ASCII NUL characters. Typically, a reset is received when the client tries to send data to the server, at the time the server has already closed the end of the connection. The one oddity, and why I say "somewhat simple" is that it expects an ASCII NUL separated [\0] file (as opposed to "new line" separated [\n], see examples below for details). You can measure the response rate of the webserver, when its operating at its full load. But for request rate 5 I was getting the reply rate as 1 when testing was done for 20 samples.
