Qure Analyzer

Qure Analyzer is a FREE solution for analyzing and comparing SQL Server trace files (workloads).

Qure Analyzer's intuitive graphical interface helps you quickly identify and analyze performance bottlenecks. And thanks to multi-dimensional grouping, sorting and filtering you can easily isolate the most resource-consuming SQL statements, applications, users, hosts and more.
Qure Analyzer also introduces the ability to compare database workloads before-and-after a hardware change, version upgrade, or tuning
effort. Even dissimilar workloads can be reliably compared, thanks to Qure Analyzer’s powerful equalization and weighting capabilities.
Both SQL Server trace files and SQL Server trace tables are supported.
