This subsection describes the memory required for processing each request. One request indicates the operations from the receipt of the request from the Web Service client, processing of the request, until the returnof a response.

In the first request and from the second request onwards, the JAX-WS engine-specific memory used is different.

The following indicates memory usage during the first request:

memory-usage-per-request(first) =
memory-used-by-the-Web-Service-Implementation-Class + JAX-WS-engine-specific-memory-usage(2.43 MB)

The following indicates memory usage from the second request onwards:

memory-usage-per-request(second-time-onwards) = 
memory-used-by-the-Web-Service-Implementation-Class + JAX-WS-engine-specific-memory-usage(119.9 KB)

Also, the formula for calculating the memory usage when multiple requests arrive per unit time is as follows:

memory-usage-per-unit-time = 
memory-usage-per-request(first) + {memory-usage-per-request(second-time-onwards) (number-of-requests-processed-per-unit-time - 1)}
