Performance Services

Quorum provides a comprehensive array of system, application, and network performance services on a variety of platforms. We specialize in performance troubleshooting and optimization of complex cross-platform systems.  We cut out teeth on IBM AS/400, iSeries and IBM i performance.

As platforms and technologies have grown more interdependent, the need to effectively design systems for performance and quickly troubleshoot complex cross-platform applications application performance has grown as well.

Unbiased, vendor-neutral advice

We don’t sell hardware.  We don’t sell software.  We don’t sell tools.   We can focus on giving good advice and fixing problems fast.

Fast, unbiased troubleshooting

Unlike your hardware and software vendors, our team doesn’t need to “point fingers”, or stop at the edge of a particular system.  We don’t push our team to “close tickets” before the problem is really solved.  We bring a dedicated team together who work together to solve complex cross-platform problems – and most of our experts have multi-platform technical skill.

We simply track down the source (or sources) of the problem, and show you the best ways to resolve the issue – considering cost, timeline, and available skillsets.

Unlike hardware and software vendors, we have no hidden agenda:  We don’t sell hardware.  We don’t sell software.  We don’t sell tools.

Design without the sales pitch

We can help select the best platforms, tools, and technologies for building or enhancing performance-critical applications.  Since we don’t sell hardware or software, we can be objective, and help sort though all of the sales pitches.

Bottom line: We help our clients design and troubleshoot performance problems – small or large.
No hidden agenda: We don’t sell hardware. We don’t sell software. We don’t sell tools.
