BRUDEN-OSSG professionals know that real performance improvements start at the application level. They work with the customer to:
- Get a quick understanding of the application:
- They have worked on a variety of applications and understand what it takes to put an application together from an operating system perspective.
- They know the performance tradeoffs in design decisions.
- They query and listen to the customer about how the application was designed.
- Analyze the bottlenecks:
- Our professionals understand the operating system at the internals level.
- They know how to read and interpret the performance statistics generated by a wide variety of tools.
- They know how changes should affect the performance of an application, before they make them.
- After a customer interview, to identify goals, they determine the potential gains and provide a flat-rate for a solution.
- Provide a cost-effective solution to the problem:
- They work with the customer to either recommend or implement application changes.
- They provide a follow-up analysis to validate that the performance has improved.
The BRUDEN-OSSG guarantee is that if the customer follows our guidelines and does not see an improvement in performance, the customer is not charged.
BRUDEN-OSSG experts have a proven track record of performing effective tuning.
In cases where the customer does not have access to the application, BRUDEN-OSSG can provide services to improve the
interface between the application and the system, such as effective memory and
caching usage.
While most system parameters and kernel attributes are sufficiency related, as opposed to tuning
related, BRUDEN-OSSG does not focus on this method as a tuning option; for example, there is
typically no "golden" parameter to tweak (unless one was improperly
set previously.) However, BRUDEN-OSSG does provide an analysis of system
parameters and kernel attributes as part of any analysis.
In cases, where hardware upgrades may be the most cost-effective solution, BRUDEN-OSSG assists the
customer in determining the appropriate hardware to meet their needs.

BRUDEN-OSSG has extensive
background utilizing operating system tools for analyzing system crash dumps, system and
process hangs, and misbehaving applications. More importantly, it has the
technical depth to analyze the data, understand the predicted behavior, and in
most cases find a solution, or in worst case, a workaround, for the problem.
In some cases, BRUDEN-OSSG helps you through the escalation process, as the
ultimate problem may be embedded within the operating system.
With certain problems, there may be a coding issue that can be used to resolve the problem. The BRUDEN-OSSG
staff helps point you to the cause of the problem, and makes coding recommendations to assist in problem resolution.
They do not stop at "There is a problem in your application," if you work with them on understanding your application.
