“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.”

Cut 62% of  your run time allowing for more processing. What is that worth to a 24/7 data center?

“We saw improvement here that exceeded what we had been guaranteed. At the conclusion of the effort, I wrote a process that analyzed our SMF data to report on performance-related improvements that were realized. I put this into a spreadsheet and graphed it for a presentation at our technical architectural meeting. My boss was very satisfied with the improvements that we achieved…. (as was I).”

“I would recommend TurboTune to anyone attempting to improve performance and reduce costs.”

“I was in charge of Citibank’s dual Asia Pacific Data Centers in Singapore. This was the largest Data Center complex in Asia and serviced dozens of countries including Singapore and all of Southeast Asia. We had some software problems with CICS and the like. Critical Path Software and TurboTune came to our rescue sending its best people to Singapore, and that made a huge improvement to the speed and efficiency of both data centers. ”
