View ArticleRe: sybase thread model and cpu/core/thread at system level
A lot depends on the actual CPU usage by ASE. First, as you likely understand, a chip thread is not 100% scalable. It only works if the CPU core is idle while waiting for a mutli-cycle operation...

View ArticleRe: Same query, different query plans on different, identical servers
