Our consultants gather requirements and generate a performance test proposal. They develop automated performance test scripts and scenarios and implement monitoring across your system servers and network. They conduct a series of performance tests against your system based on the agreed approach as defined with our test proposal.
Environment “noise”, is the resource utilisation overhead that occurs on the servers in the production environment, that is not directly attributeable to the active elements of the application under test. Environment noise is usually composed of application and environment management overhead activity due to other applications or the application under test. Whilst the Application “noise” of the application under test can be readily established in the test environment, application noise of other applications operating in the production environment are more difficult to establish, but can be measured over a period of several months of data.
Noise Determination
This is principally determined from data collected in the production environment. The following production environment data is required from all servers in the delivery chain:
- CPU utilisation
- Disk transfers
- Number of packets
- Process information (%CPU, memory and #threads)
It is preferable that these measurements be collected over a period of at least one month.
