The Oracle Database Machine beats competing solutions on bandwidth, load rate, disk capacity, and transparency.” Christian Maar, CIO “Every query was faster on Exadata compared to our current systems. The smallest performance improvement was 10x and the biggest one was an incredible 72x.” Simeon Dimitrov, Enterprise Resources Manager “Call Data Record queries that used to run for over 30 minutes now complete in under 1 minute. That's extreme performance.” Grant Salmon, CEO, LGR Telecommunications
