Christol Consultants Group has the skills and tools to quickly determine the root cause of problems and improve the performance of your systems.

Due to the many variables that impact system performance (the database, applications, servers, storage, and network infrastructure), tuning is an iterative process. Therefore, most tuning engagements are at least 3-4 weeks in duration, and depend on the size and complexity of the environment.

Be the first across the line

The most common tasks performed during the performance tuning:

Hardware Assessment: monitor disk I/O rates and latencies, CPU and memory usage; and identify and isolate specific performance issues and I/O bottlenecks

System Performance Analysis: collect and analyze performance data over a period of time for baseline

Database Server Analysis: analyze SQL Server, Oracle, MySQL and operating system statistics to determine the overall health and usage of the system

Stored Procedure and SQL Analysis: evaluate the database system in terms of query execution to determine if performance can be improved by either modifying SQL statements or execution plans

Schema Analysis: analyze the database schema in order to determine if changes should be made. These changes may be immediate, such as a new index, or long term, such as partitioning or distributing the database

Application Architecture: determine if the architecture is appropriate and recommend architectural changes, such as the use of a transaction monitor, cluster, or changes to the database layout

At the end of the engagement we will provide a Final Recommendations report; an executive summary of the recommendations and supporting details for modifying your overall system design and configuration in a manner tailored to your specific application usage and growth requirements.
