Software Performance Engineering (SPE) is a full software system life-cycle approach, that begins with design, and continues throughout the development, testing, and deployment phases. The Ian Thomas Group, LLC's (ITg) expert engineers, architects, and developers, work together to implement a holistic methodology for the resolution of software issues.
SPE is designed to ensure predictable performance in systems, by specifying and analyzing quantitative behavior at every tier. Our Architects and Engineers, carefully consider performance requirements, the actual design, and the environment in which the system will be running. Analysis is based on modeling techniques and design tools.
SPE ensures that software systems adhere to their performance requirements, aiding in an organization’s overall business success. ITg’s SPE expertise, offers organizations the following benefits:
Clients deserve and demand a high speed, world-class technological experience. ITg utilizes mathematical modeling to iterate through multiple design options, to ensure the delivery of software that will satisfy our client’s performance requirements. These models:
A significant return on investment is realized, as a result of employing these models during the design phase; architecture rework costs less per improvement than recoding an application or making unnecessary investments in infrastructure resources.
We train and coach developers on the use of mathematical models, to ensure software
routines adhere to performance-resource allocations and service-time requirements.
Measuring resource utilization during code construction enables software developers to write code that is both functional, and high performing. The performance data that is collected against the actual source code, improves the initial performance models that were created during the architectural stage. Development performance models continue to build confidence in the ability to accurately predict the performance scalability of the final software system. The investment in, and use of, performance models at this stage, reduces the need for extensive optimization after code integration, which in turn assures a more efficient and cost-effective software system.
ITg properly sizes servers, storage, and network resources, by leveraging a combination of mathematical modeling, load testing and analysis. These models are employed during the system design, development and testing phases, as well as throughout the ongoing production process. ITg utilizes this systematic approach to predict and maintain the most cost-effective and optimally performing infrastructure.
The purpose of software performance testing is to find out how the software system
works under varying stress loads and activity. Using a combination of multiple tests,
we are able to determine the parts of the program that reduce its effectiveness.
Load and stress testing, enables integrated software systems to pass through a final
phase of performance validation, prior to deployment. Through this process, ITg
offers its clients the ability to approximate production workload, against a sample
of production hardware, to execute the final pre-production coding and system optimization.
ITg offers a load and stress testing solution that provides an easy-to-use and cost-effective way to load test the performance of web applications and websites. Unlike most testing solutions on the market, it does not require any software or hardware purchases and provides results faster and less expensively than traditional performance testing.
