FYI - From the linux-kernel list. ----- Forwarded message from Ingo Molnar <mi...@el...> ----- Date: Wed, 21 Mar 2001 13:11:35 +0100 (CET) From: Ingo Molnar <mi...@el...> Subject: [patch] pagecache SMP-scalability patch [was: spinlock usage] To: Anton Blanchard <an...@li...> Cc: Linux Kernel List <lin...@vg...> Anton, if you are doing SMP-intensive dbench runs, then check out the SMP pagecache-scalability patch (against 2.4.2-ac20): http://people.redhat.com/~mingo/smp-pagecache-patches/pagecache-2.4.2-H1 this patch splits up the main scalability offender in non-RAM-limited dbench runs, which is pagecache_lock. The patch was designed and written by David Miller, and is being forward ported / maintained by me. (The new pagecache lock design is similar to TCP's hashed spinlocks, which proved to scale excellently.) (about lstat(): IMO lstat() should not call into the lowlevel FS code.)
