Around half the world’s VAX users are losing out on the full performance potential of their systems, according to a survey carried out by Wimbledon-based Demax Software Ltd. The company approached 100 US and European VAX users and found that over 50% of the systems were spending too much time on memory management activity, operating in Kernel Mode for 40% on average, and sometimes up to 90%. Tuning the systems could result in a 25% increase in performance, said the company, which is offering free performance tuning analysis to system managers. Demax hopes that recipients of the test will go on to buy its Dynamic Load Balancer performance utility, claimed to increase VMS throughput, and priced at UKP1,200 on the MicroVAX II, rising to UKP3,000 on the VAX 8900.
