Large Insurance Organization



One of the largest US insurance providers was able to reduce their software costs by 30%. They were able to increase their I/O by 453% and reduced response time by 57%. The entire project was completed in 3 months.



The client was one of the largest not-for-profit health insurance organizations in the US. The insurer’s membership included large and small groups, individuals and families.



The mainframe environment was at the core of their business. They were facing operational inefficiencies, increasing MLC costs and exuberant software licensing fees. They had tried to optimize their mainframe for a number of years but couldn’t find a solution that worked.



The mainframe was accessed by both CICS and nightly batch processing, there was also a significant daytime workload. The client was facing the addition of new hardware (e.g. a new engine) at significant expense to carry the workload.



CPSI performed an analysis of the mainframe and provided a detailed report that identified improvements to:

  • CPU utilization for Batch & Online processing
  • I/O measurements (i.e. EXCP counts) for Batch & Online processing
  • Millisecond response time for Batch & Online processing
  • Elapsed Time improvements for Batch processing
  • Recovery of “over allocated” disk space (due to non-optimal allocation)
  • The client implemented CPSI’s recommendations in 3 months and achieved immediate results.


All of the following results were provided by the client.

  • Response Time Reduced by 57.78%
  • Total I/O Increased by 453.21%
  • Max I/O Response Time Reduced by 18.96%
  • Max Server Time Reduced by 12.80%
  • Pending Time Reduced by 49.98%
  • Connect Time Reduced by 58.82%
  • Cacheable Increased by 469.31%
  • Cache Hits Increased by 384.40%
  • Cache Hit Reduced by 14.92%
  • Disk Reduced by 59.09%



A Fortune 25 West Coast Bank was experiencing various performance problems. Erroneous CISIZE errors were taxing the system. Upon an extensive analysis, TurboTune® identified the problem. Once the TurboTune® recommendations were implemented the senior tech on the job wrote us the following email:

“We installed and we saw GREAT results. The Fiche processing that normally begins the 3rd business day of the month, and has more than 45,000 jobs, usually runs 24 hours. It just ran in under 9 hours!! Thank you TurboTune for the file recommendations. This worked out nicely.”

A savings of 62% in their mainframe run- time allowed the bank to process additional jobs. These jobs were previously being held for 24 hours for the Fiche jobs to finish.



An airline reservation system (for a top US Airline) had outsourced their mainframe processing. The client was facing exorbitant charges for increased MIPS utilization and was experiencing long run-times for a month end job. The job was a CICS IMS Data Base containing 200 million records running a Month End Edit. The job ran for an unacceptable amount of time, 14 days each month.

The client tried in vain to get the outsourcer to fix the issues but they could not identify the issues. The client engaged with CPSI. CPSI performed an in-depth analysis using the TurboTune® suite of tools.

TurboTune® identified several run-time improvements and specific recommendations were made. These recommendations were then tested and implemented into production. The client was able to dramatically reduce the run-time of the job from 14 days to 18 hours. The CPU remained stable and the job remained in the same low priority 8 Meg Region.




A large New York based financial services firm was in the process of extensively reprogramming their mainframe applications. A single normal workday was inadequate to test the massive amount of programming changes.

To further complicate things, their mainframe processing was outsourced to a hosting provider. When testing would overflow into weekends, they would get hit with increased usage rates. They also had to pay for additional support, programmers and operators that were required during these periods. This cost structure was exorbitant and not maintainable.

Critical Path was engaged to improve mainframe efficiency by shortening on -line transaction response times, reducing batch consumption, and reducing run -times in the batch production cycle.

The TurboTune® Analysis was completed and a full Audit report was provided to the client. The client implemented the recommendations, resulting in performance reductions, on an average, of 39%. This reduction allowed testing to resume during normal work hours and delayed costly hardware upgrades for 18 months.

BANK SAVES $20,000,000 IN MIPS


At the onset of a merger between two large financial institutions CPSI was engaged to improve performance and recover DASD. The TurboTune ® Analysis identified in excess of 125,000 necessary file improvements to the existing 1,500,000 files.

Collaborating with application managers, the CPSI team assisted with implementation and created the internal tools necessary to identify on-going performance concerns.

Upon the completion of the project, the merged facility had achieved savings in excess of $20 million. These savings came from reducing the clients MIPS utilization; eliminating 10,000 hours in batch processing time and recovering 3 TBs of DASD. Additional performance options and parameters were identified as well.




A multi-national banking institution wished to consolidate all its data centers, residing in seventeen separate countries, into one center in Singapore. The Singapore location lacked the necessary storage space for the consolidation. Additionally, their Sydney data center was experiencing severe online and batch window problems.

Critical Path was engaged when it became evident the vendor of the Systematics package would be unable to successfully solve the issues. The TurboTune® Analysis was completed in one extended overnight session. 800 file improvements were recommended and fully implemented resolving 100% of the performance issues.

The file reorganization also provided a reduction of 40% of the DASD footprint paving the way for the complete migration of all global data centers to the Singapore location, saving the bank untold millions.
