A method is described to determine the number of personal computers (PCs) that can be supported by an IBM PC Network Server with satisfactory performance. This method involves characterizing workload for a given usage environment and then calculating frequency of concurrent resource requests using binomial probabilities. The resulting concurrency figures are judged according to a criteria for acceptable concurrency which is derived from measurements. First, inputs are required to describe the usage environment. This is done in terms of the number and type of resource requests generated by one workstation (or by whatever other configurable unit is generating resource requests).
