I was asked to evaluate the potential benefit of using Veritas Quick I/O for one of our databases. I put together some simple tests to gauge the expected impact of Veritas Quick I/O on Oracle performance. The tests were designed so that the only variable when running the test scripts was type of datafile the scripts were reading from or writing to (i.e., Quick I/O or non-Quick I/O).
The results of the tests were very surprising. Only the performance of large DDL operations, such as copying tables and creating indexes, was significantly improved after implementing Veritas Quick I/O for an Oracle datafile. Performance of DML operations ranged from marginally improved to markedly worse after implementing Veritas Quick I/O for an Oracle datafile. Large selects were particularly poor performing with Quick IO. Are these results typical? Are there any issue I should be aware of? We're running Oracle 8.1.6.3 on Solaris with Veritas Database Edition for Oracle 2.1.1. TIA, Ed __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
