IBM Rational ClearCase is an industry-leading software configuration management (SCM) solution that improves productivity by providing sophisticated version control, work space management, parallel development support and build auditing. It is typical for developers using IBM Rational ClearCase to be geographically distributed, working remotely either in small branch offices or from home. The IBM Rational ClearCase Remote Client (CCRC) allows remote developers to connect to distributed ClearCase databases and perform all SCM-related operations remotely; however, wide area network (WAN) latency can negatively impact application response time for operations that modify and transfer files across the WAN. This can result in lost productivity and higher development costs. For mission-critical applications such as IBM Rational ClearCase, alleviating the performance degradation of both unsecured and secure content over the WAN is imperative.
This white paper discusses the demonstrable response time performance gains that can be achieved by the IBM Rational ClearCase application suite when used with Certeon’s aCelera Virtual Appliance for Application Acceleration software. The performance tests discussed in this document were conducted by Certeon for the Ready for Rational CCRC Certification effort. The testing scenarios illustrate an improvement of up to 93 percent in CCRC response time.
This paper also provides an overview of Certeon’s aCelera software and its unique Application Acceleration Blueprint for IBM Rational ClearCase. It discusses Certeon’s Secure Acceleration Technology (SAT), which allows Certeon to effectively accelerate encrypted SSL traffic over the WAN without compromising data integrity.
Key findings from these performance tests:
- Certeon speeds CCRC performance up to 93 percent.
- CCRC performance with aCelera improves as documents increase in size.
- CCRC performance with Certeon is consistent as the number of users increases.
