Well, there's a known issue that IA-32 systems with more than 4GB of memory use an extension known as "PAE" to bank-switch between the banks of memory. Any time you switch banks, there's a fair little bit of work to be done. That includes multitasking systems that need to context switch a few thousand times per second. The "fix" for this problem is to rewrite all of your applications so that they become conscious of which bits of memory they're using so they can tune their own behaviour. This, of course, requires discarding useful notions such as "virtual memory" that are _assumed_ by most modern operating systems. The fix is to buy hardware that hasn't been hacked up so badly. -- select 'cbbrowne' || '@' || 'ntlug.org'; http://www3.sympatico.ca/cbbrowne/lsf.html "There is something in the lecture course which may not have been visible so far, which is reality ..." -- Arthur Norman ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
