Load Impact

Automated and on-demand performance testing for developers.

5.0/5 (3 reviews)

Load Impact overview


Time is money – Most websites and applications are revenue generating tools for companies and
poor performance translates to customers lost.

Performance matters - 47% of PC visitors and 69% of tablet visitors expect response times equal to or below 2 seconds (Akamai, 2012); 18% of shopping carts are abandoned due to slow website performance (Radware, 2013); 68% of website owners experienced performance or stability problems in 2012 (Load Impact, 2012).

The complexity of mobile – Performance is the most important differentiator when it comes to mobile app adoption, use and abandonment rates. A small delay in load-time might seem like a minor issue, but in reality even a small change in latency – from 2ms (broadband) to 400ms (3G network) – can cause a page load time to go from 1 second to 30 seconds.

Cost Savings – There are many parts of the web architecture such as web servers, load balancers, firewalls, Internet service providers, third party applications and local internet service providers. Load testing allows you to pinpoint bottlenecks in different parts of the web architecture so you only upgrade what you need to.

I have woked with multiple development projects in past few years. So i have good experience with couple of nunfuntional testing tools. load impact is one of them. Attractive user friendly user interface and simple workflow. I have used this application under multiple environments. I have used this to test some 3rd party API's and couple of websites. It comes with attractive automation functionalities. Support multiple 'cl technologies'. I can execute daytoday load test executions in my local machine and complex executions with load impact cloud.I can simply automate my workflow without any delays.

Easy and well done load testing tool

I very much like the Load Impact stress testing tool. It is very easy to set up, very easy to configure to do specific use cases and overall just a high quality tool which I can imagine can be used by anyone. Load Impact comes with 5 free stress tests. I hit my 5$ DigitalOcean droplet with Load Impact and I managed to crash the mysqld daemon two times running at around 28 concurrent users. Load Impact very easily showed me that both memory and CPU was peaked on my box, and also precisely showed me the max concurrent users my platform would allow. Via a chrome extension you can very easily create use case script for Load Impact. Just configure your browser to navigate through Load Impact and they will record everything you do through your own solution and create a script for it. This allowed me to create use cases specifically for some parts of my websites, e.g. for searching, navigation and more. Incredible easy to get started Free (up to 5 free stress tests) Innovative and very cool proxy feature Nice graphs and pictures Able to spread load coming from different locations and source IP's Has an agent you can use to pick up server data

Really easy to deploy load testing solution. Unlike software base solution, Load Impact is on demand.On demand, relatively cheap

Realistic simulated users – We simulate traffic exactly how it would happen in real life. Our Virtual Users (VUs) use multiple concurrent TCP connections when loading resources from a single target host; can ramp-up from 0 to 100,000 users in under a minute; use DNS just like real clients (cache according to TTL, etc.); have extensive HTTP support including redirect behavior, custom headers, all verbs, cookie handling, compression handling, etc.

Mobile testing - Quickly create a load test which simulates different mobile network conditions - such as 3G, 4G, Edge, etc - and easily record mobile user scenarios using our hosted proxy recorder.

API testing - Exercise the set of calls documented in your API exactly as your users would. Ensure that resources exposed by the API can be created, listed, updated and deleted appropriately under expected load.

Large-scale load generation – We are able to generate load levels as high as 1.2 million concurrent users with multiple IPs and locations, depending on requirements.

Automatic and advanced scripting - Script user scenarios in Lua, using our IDE with code completion, JSON and XML parsing, data parameterization and more. Or analyze a web page and generate a load script automatically - no programming required.

Server metrics - Install our lightweight monitoring agent on the servers you are load testing and get detailed information about resource utilization (CPU, memory usage, etc) on your machines during your load test

Scenario recorders - Record an HTTP session using our proxy recorder or our Chrome Extension and let the simulated users perform the same actions during the test.

Browser emulation - Configure your load test to emulate popular browsers such as Firefox, IE, Chrome, Safari etc. or more exotic types of user agents such as GoogleBot

Multi-geographic distribution of load - In a single test, we can generate load from up to 10 different locations simultaneously. We can add even more locations upon request.

Continuous Delivery testing - Use our Continuous Integration plugins (TeamCity and Jenkins) for easy implementation or our raw access API and SDKs (Java and Python) for greater control and flexibility.
