Questions?

Can I downgrade/upgrade my subscription?

Yes, you can upgrade at any time in app. We will prorate your current term against the new one when upgrading. If you wish to downgrade, simply choose the plan and it will start at the conclusion of your new term.

Can I cancel my subscription at any time?

Yes, you can cancel your subscription anytime you want during the subscription term. You will not be charged beyond the month you cancel for monthly subscriptions. Service will be retained at the subscribed level until the last day of the subscription term.

Is this a recurring subscription?

Yes. Load impact is a subscription based service. Your subscription will auto-renew at the end of the term unless you cancel. To check your current expiration/renewal date, please check the billing menu in app. Load Impact does not offer refunds on subscriptions.

Can I get a variable rate or customized plan?

We offer variable rate subscriptions that allow you to run as many individual tests as you want - up to a certain load level. As your business grows, we'll automatically move you up to a higher load testing level. We can also create custom plans to match your test frequency and load volume needs. Please contact us for a quote.

Do you offer discounts for non-profit organizations?

Yes, we do offer a significant discount for non-profit organizations. Contact us with a description of your needs and we will be happy to oblige.

What are the different payment options?

The easiest way to pay is by credit card while you are logged into the Load Impact app. You can also pay by wire transfer; please contact us to set this up.

Can I get help with scripting, results analysis and integration?

Yes. If you need any help at all with testing and/or results analysis, we encourage you to contact us to receive a quote for our professional services.

What if my test aborts, do I get a refund?

Yes, if the test was aborted by the system you will get a full refund. If the test was aborted by you, then you will get a partial refund depending on how early you abort. But we're flexible, so contact us if you would like us to honor a full refund request. This policy applies to version 3.0 pay-per-test credits only.

What are VUs and how many do I need?

Virtual Users, VUs, are the simulated clients we load onto your system. They load objects in parallel, just like a real browser would. To know how many you need for testing, apply this formula: VUs = (peak hourly_visits * avg. visit_duration in seconds) / 3600.

What is the difference between VUs, RPS and Clients/Test?

- VUs: Virtual Users: simulated virtual users or clients that concurrently generate load onto your system, given one or many scripted user scenarios.
- RPS: Requests Per Second: a measure of throughput as number of requests generated onto a system every second. See previous question for details on how to convert VUs to RPS.
- Clients/Test: An accumulated number of requests (or scenarios) generated throughout the runtime of a single test. Load Impact does not currently support this way of measuring scale and sizing of a test. We find the VU and RPS approaches are best.

What are Requests per Second (RPS)?

Requests Per Second, RPS, measures the estimated throughput of load we will generate onto your system. RPS is an estimated calculation based on:
- Each virtual user is capable of generating multiple concurrent TCP connections when scripted using `http.request_batch.`
- For Load Impact 4.0 each Virtual User can generate 10 or more RPS.
Creating tests based on RPS is useful for load testing APIs. See this article for more details on how to set up your throughput in Load Impact.

What is a Server Metrics Agent?

We offer the option to install Server Metrics Agents on your target machines. This makes it possible to collect information like, CPU usage, memory usage, disk I/O, network I/O, during testing. You can also add other custom metrics using Nagios plugins.
