No, Go 1.26 Did Not Make Your Service 40% Faster

Go 1.26 introduces Green Tea as the default garbage collector, shifting mark-and-scan work from individual objects to pages.

By scanning memory in page-sized batches, it improves locality and reduces CPU cache misses, which can lower GC stalls and overhead.

The widely cited '40% faster' figure refers to collector-related work, not a blanket 40% speedup for every service.
