Static resources, also called embedded resources, are objects like images, scripts, and fonts that are retrieved by the main HTML of a webpage. They can have a significant effect on response times for both [[Frontend performance testing]] and [[Backend performance testing]]. Adding static resources to a [[Load Testing]] script is an essential part of [[Making load testing scripts more realistic]]. Scripts that do not fetch these resources will not be accurately simulating a real user accessing the application. ## Concerns ### Third-party resources Consider excluding static resources fetched from third-party providers unless you've gotten their permission to run a load test on their servers. The best time to do this is when recording a transaction, so that some known domains are filtered out automatically. ## Excluding static resources in [[Load Testing Tool]]s - [[Excluding static resources in JMeter|Excluding static resources in JMeter]]
