Common questions

QWhat is a Load Impact Virtual User (VU)? Load Impact VUs are more powerful than the traditional VUs used by other testing tools. Our VUs will load objects in parallel, just like a real browser would. This means, by default, our VUs are nearly four times more powerful than the VUs of other load testing tools. QDo my pay-per-test credits rollover month to month? Yes. Any unused test credits will rollover month to month. QWhat 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. QCan I get help with scripting, results analysis and integration? Yes, if you need help beyond what our Support staff can provide, we encourage you to contact sales@loadimpact.com to receive a quote for our consulting services. QDo you offer discounts for non-profit organizations? Yes, we do offer a significant discount for non-profit organizations. Simply write to sales@loadimpact.com with a description of your needs and we will be happy to oblige.
QWhat if I need to run a test that's beyond my subscription level? In this case, we encourage you to take advantage of the pay-per-test discounts included in your monthly subscription. This allows you to run larger tests whenever you want without having to upgrade your subscription. QCan 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. QCan 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. QCan 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 sales@loadimpact.com for a quote. QWhat 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.
