The following reply was made to PR kern/188911; it has been noted by GNATS. From: Ed Maste <emaste@freebsd.org> To: bug-followup@FreeBSD.org, ikosarev@accesssoftek.com, Viktor Kutuzov <vkutuzov@accesssoftek.com> Cc: Subject: Re: kern/188911: [libc] sysctl(KERN_PROC_VMMAP) takes too long Date: Mon, 12 May 2014 22:33:41 -0400 Yes, this is the cause of the slowdown; it takes a long time to iterate over 8TB 4K at a time.
