Results for scenario 2: IBM HTTP server

Edit online

For scenario 2 the IBM HTTP server (IHS) web server drives the SSL connection.

This means that the HTTPS requests are processed by the IHS web server and IBM WebSphere Application Server (WAS) executes the application logic. IHS runs on the same Linux™ server as WAS and the communication between IHS and WAS is not encrypted. The self-signed certificate was stored in the PKCS#11 cryptographic ICA token and was defined with a key size of 2048-bit, where the scaling is done over the cryptographic setups. A key size of 4096-bit was chosen in a second measurement series.

Note: The workload generated (number of virtual users) by the workload driver is kept constant across all measured scenarios.
