RTO Software's TScale* 3.0 adds Application Shaping and significant new Application Optimization Functionality Application Shaping provides for automated control of "rogue" applications For immediate release SUWANEE, GA.- October 6, 2003 - RTO Software today announced TScale* 3.0 and the Performance Management Console (PMC) 3.0. The latest improvements to TScale combine Application Optimization with Application Shaping(tm) in a single solution to help companies using Citrix® or Microsoft® terminal services increase user satisfaction while also lowering IT costs. TScale is the first and only product in the marketplace that combines Application Optimization with Application Shaping in one easy to install and easy to administer product. Applications Optimization improves the performance of applications at times of heavy user or work load, increasing server capacity and reducing end user complaints about slow response time during busy periods of the day. Application Shaping stops rogue applications from using more than their fair share of CPU resources - radically improving the user experience and freeing administrators from the time-consuming task of manually addressing issues arising from these rogue applications. "The combination of Optimization and Shaping into one product at an attractive price is an example of our continuing commitment to give the terminal server community great value in an easy to afford and easy to implement package," said Bernd Harzog, CEO, RTO Software. TScale's new Application Shaping gives system administrators of terminal servers pinpoint control over application behavior, providing consistent, reliable response time for key applications to enhance end-user satisfaction. TScale's flexibility allows administrators to implement policies on a user and scheduled basis to automatically prevent instances of rogue applications from running away with CPU resources and damaging end user experience. Application Shaping consists of two features that can be applied separately or together to control rogue applications. Affinity allows an administrator to specify which of the CPU's in a multi-CPU server an application should run on, allowing the administrator to limit the damage of a badly behaved application. Priority allows the administrator to direct the CPU to service other applications running on that CPU before giving more resource to the rogue application. Together these features can give an administrator much greater control over application performance, markedly improving the performance of the server. "Our entire user population utilizes our Citrix servers to run a complete line of business applications, some off-the-shelf, some custom written. TScale 3.0 increases both the number of concurrent users that we can support on our Citrix servers, and it prevents the impact of misbehaved programs upon our end users' experience", said Jan Broucinek, System Manager at Arthur Rutenberg Homes in Clearwater, Florida. "Prior to the addition of the new Application Shaping features to TScale, we had several instances a day of Word, Internet Explorer or Voloview running away with CPU's on our servers. The Application Shaping features of TScale 3.0 give us an automated system to prevent these occurrences from impacting our users' experience". TScale 3.0 also includes a new optimization, Registry Compression. This optimization reduces the amount of virtual memory used by the registry in terminal server environments, making the freed up virtual memory available to support more concurrent users. Registry Compression is an addition to the existing set of three application optimizations in TScale, creating a robust and unparalleled set of functionality. TScale 3.0 will be demonstrated at the upcoming Citrix iForum 2003 show October 13-15, in Orlando, Florida, and is scheduled to ship in November. About RTO Software RTO Software is pioneering a new category of performance management tools. RTO's products are unique in that they continuously and automatically analyze how applications use resources on servers, and then implement, on a scheduled basis, optimizations unique to that server. RTO's first product, TScale, continuously and automatically improves the performance of applications running on Citrix and Microsoft terminal servers.
