PROBLEM TO BE SOLVED: To reduce the response time of transaction processing from a host by improving the hit rate of a cache when executing each processing process. SOLUTION: A processing distribution device has a plurality of processing process execution means, and a dispatcher process execution means. Each processing process execution means executes the processing process. The dispatcher process execution means distributes processing occurring by requirement or the like from the host to the processing process execution means. Here, each processing process execution means has the cache, and transmits cache clear notification to the dispatcher process execution means when clearing the cache. When the dispatcher process execution means distributes the processing to the processing process execution means, the dispatcher process execution means monitors a cache survival time of each processing process by use of the cache clear notification, and allocates the processing to the processing process execution means having the longest cache survival time.
