I am using vdbench to replay a trace I ran using SWAT302. This all
work fine, now I want to double the workload using the same trace flatfile.
Can this be achieved by simply doubling the iorate or does it require something more?
doubling the iorate value will do what you want by cutting the i/o inter arrival times in half.
This means that if you have a trace of 30 minutes, Vdbench will try to replay this in 15 minutes.
Nothing else is needed.
