Zen-QL: Performance Vs Feature

There was a time we tried to compete with LINQ (which we love so much) while having fewer features than it. We sometimes magically outperformed LINQ by a lot, but that wasn’t a stable result. Since v2, we started adding more features and even expressions to be more developer-friendly. While we’ve mitigated the cost and performance issues considerably, we can say we’ve reached LINQ-level performance. Still, as stated earlier, benchmarks are highly environment-dependent. Even so, we believe that even with the usage of Sifu Expressions, we can confidently claim to have a fast query language. In fact, we’re doing good in our 50,000,000-record filter and validation benchmark. (1.2 to 1 sec)
