Hi Andrew, They have also different information on older documents,
The document "Performance Tuning for Business Service Management" dated from October 2007 states on page 19: "If the thread count is set too low, the AR System server will have low CPU use, poor throughput, and potentially poor response time under high load. Suggested thread counts are* three times the number of CPUs for fast and five times the number of CPUs for list*. So a two-CPU box might have six threads for fast and ten threads for list. BMC Software recommends using the same value for the minimum and maximum setting." And the document "Reference Architecture for BMC Service Support Solutions using BSM 7.6 Components" dated from November 2009 has the following information on page 12. "*On all platforms, when configuring the AR System server threads, do not exceed about 60 to 70 threads for all list, fast, and private queues*. At higher thread levels, the throughput stagnates and can even be reduced. Rather than increasing the number of threads in one server beyond this number, BMC recommends that you add multiple servers in virtual machines on the same hardware and configure each with up to 60 threads."
