SeaCat Performance Test

We decided to perform this test to validate our architectural, design and implementation decisions in regards to SeaCat performance. Our goal was to build the best-in-class product using the most advanced techniques to deliver highest possible throughput yet not compromising the security of the communication in any way. Results of the test have been fed back into our development team to improve further overall performance characteristics of the solution.

We want to illustrate SeaCat's performance related to HTTP and HTTPS protocols. SeaCat provides speed that is close to HTTP and the level of security that is at least equal to HTTPS. If performance is important to you, you will be able to put all three methods in some perspective.

Measured numbers should help you in deciding about your environment sizings.

Test configuration

The test environment has been configured using the following architectural recommendations (see bellow PDI diagram). We build it using Amazon AWS EC2 service.

The test based on launching GET request that retrieves a certain XML file from the HTTP host. This cycle of request and response is called transaction for the sake of this test.

We build custom performance tool for SeaCat, modelled after well-known ab tool from HTTP Apache server suite. ab tool is also used for reference testing of HTTP and HTTPS which is configured in the same way (or as much as possible).

We crafted 128 B, 512 B, 1 KiB, 2 KiB XML, 4 KiB, 8 KiB and 16 KiB XML files that are served by HTTP hosts during the test.

Further details of test configuration are attached at the end of this article.
