This paper details a series of performance tests that were conducted on prototype industrial computer systems at the ESRF. PICMG1.3 is a new industrial computer standard that comprises PCI Express bus. At the ESRF, camera detector systems are producing high bandwidth data. A data acquisition system could be designed around a PICMG1.3 compliant system. The study emphasizes Gigabit Ethernet data input and intermediate data storage on a RAID disk system. PCI Express bus characteristics are explained shortly and their influence to the system architecture is discussed.
