C\TREK Corporation provides performance tuning software, consulting, and training services for IBM mainframe CICS environments. Its core product, C\TREK Expert CICS Performance Tuner, is not a typical real-time performance monitor. Instead, it complements traditional CICS monitors by automatically analyzing large volumes of CICS operational data, identifying performance bottlenecks, and delivering expert-level tuning recommendations.
The product covers multiple key performance areas in CICS environments, including SIT parameters, VSAM files, NSR/LSR buffer pools, CICS and z/OS control blocks, Temporary Storage, DB2 connections, Abend handling, and more. It also analyzes external factors such as CPU utilization, paging, the Task I/O Table, Auxiliary Storage Manager, address space priority, and VTAM. CPU usage can be broken down by CICS, DB2, TCP/IP, WebSphere, MQSeries, and the operating system. Supported environments include CICS/ESA, CICS/TS, z/OS, OS/390, MVS/ESA, and CICS/TS on VSE.
The website does not disclose pricing, license tiers, or trial policies. It only mentions that users can request a demo, and indicates that customers renew their software licenses. New product versions can be downloaded from the Web. The description suggests deployment in a customer’s local mainframe environment rather than a SaaS model. No information was found about APIs, SDKs, or modern DevOps integrations.
Its strengths are its very clear positioning and deep focus on CICS performance optimization. It can automate tuning processes that would traditionally depend on the experience of senior systems programmers, including VSAM, buffer pool, DB2, and parameter tuning, while providing concrete recommendations. In theory, this can significantly shorten diagnosis time. The site also emphasizes expert support via phone and email.
The drawbacks are that the publicly available materials feel quite traditional, with no interface screenshots, sample reports, complete documentation, pricing, purchasing process, or implementation details. Its scope is also highly concentrated on mainframe CICS scenarios, making it largely irrelevant for typical Web, cloud-native, or open-source development teams.
It is suitable for enterprise data centers in finance, insurance, banking, manufacturing, and other sectors that still run mission-critical IBM CICS systems. It is especially relevant for teams looking to save senior mainframe engineering time, delay capacity upgrades, and establish proactive performance management processes. Access from mainland China is not mentioned in the source material, so it is assessed as unknown.
