Folks, We're seeing some odd issues with hyperthreading-capable Xeons, whether or not hyperthreading is enabled. Basically, when a small number of really-heavy duty queries hit the system and push all of the CPUs to more than 70% used (about 1/2 user & 1/2 kernel), the system goes to 100,000+ context switcthes per second and performance degrades.
I know that there's other Xeon users on this list ... has anyone else seen anything like that? The machines are Dells running Red Hat 7.3. -- -Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
