How long does one run of one of the benchmarks in SPECjvm2008 take?
One benchmark has a 2 minutes warmup time and 4 minutes measured runtime. During this time several operations will be performed. An operation will never be interrupted, so all threads will continue to run until all threads have completed the operation started inside the measurement interval. This means that a 4 minutes measurement period will take at least 4 minutes to complete, in some cases a noticable amount of time more.
