<![CDATA[Information system performance evaluation is a crucial step for organizations in facing technological developments, supporting the achievement of strategic goals, and increasing competitiveness in the digital era. This evaluation ensures that the implemented technology not only meets current needs but is also able to keep up with the latest technological developments. The analysis of Digilib Perbanas' performance was conducted because of emerging issues related to feature complexity that make it difficult for users. If this problem is not immediately addressed and the system is not updated, Digilib risks being abandoned by its users. This study aims to evaluate Digilib Perbanas' performance using a combination of the PIECES and GTMetrix methods. The PIECES method is used to measure system user satisfaction through the variables of Performance, Information and Data, Efficiency, Economic, Control and Security, and Service. The number of respondents in the study was 312 students from the Faculty of Information Technology and the Faculty of Economics and Business. The measurement results for the Performance variable were strengthened by the GTMetrix method to measure website speed. Data collection was carried out through questionnaires and processed using IMB SPSS Statistics 27. The PIECES calculation results obtained an average variable value above 4.2 or Very Satisfied. However, the additional test result for the Performance variable using GTMetrix was E, indicating that the Digilib website's speed is still suboptimal due to the large amount of data on the platform. The hybrid approach between PIECES and GTMetrix produces a more robust evaluation of Digilib Perbanas by combining problem-based analysis through user perceptions and functional aspects, as well as evidence-based measurements of technical data on system performance.]]>
