Common Questions

  • 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 if I need to run a test that's beyond my subscription level?

    All premium subscriptions include max capacity test(s) that allow you to run one or two large tests each month. If you need to run more max capacity tests, you may either pay-per-test or contact us for a customized plan.

  • 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 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.

  • 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 pay-per-test credits only.

  • Can I cancel my subscription at any time?

    Yes, you can stop your monthly subscription anytime you want. You will not be charged beyond the month you decide to cancel.

  • Can I downgrade/upgrade my subscription?

    Yes, you can downgrade or upgrade your subscription at anytime. You can also hold two subscriptions simultaneously. But if you wish to change plans, please make sure to cancel the first one before purchasing the other.

  • Is this a recurring subscription?

    Yes. Load impact is a Subscription based service. Users are able to cancel their subscription at any time during their term. Service will be retained at the subscribed level until the last day of the subscription. 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.

  • Do my pay-per-test credits rollover month to month?

    Yes. Any unused test credits will rollover month to month.
