Helping manage complex state changes, material flows and production parameters is the job of the MES system. Performing it effectively could require the granularity to perform transactions faster than 1/100 of a second. To test the performance and scalability of its cmNavigo MES software on hardware typically found on the plant floor rather than in high end test labs, Critical Manufacturing engineers programmed multiple test clients to perform a specified transaction set on a single application server. They then increased the number of application servers from one to four and measured the API transactional writes to each. ...
