We've not noticed any really low I/O performance. How are you running dc3dd? - So I can try and install / replicate this here. We have seen that I/O behaves differently under XenServer than it does on b= are metal (which is obvious - i.e. local SATA SSD vs. Multipath iSCSI [or simil= ar]) you will see differences (even just with 'mapped through XenServer' "Local Storage"). It could be dc3dd / the stuff you're running is a particularly 'bad case' f= or the I/O. e.g. In an equally 'synthetic' test - a regular "dd if=3D/dev/zero of=3Dtest.dat bs=3D64k count=3D10240" on our our test pool here (which has = two paths iSCSI over Gigabit) we get around 220Mbyte/sec to a FreeBSD DomU. That may well be a best case - and you may well have hit some worst cases. -Karl --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-xen@freebsd.org Wed Sep 14 13:13:12 2016 Return-Path: Delivered-To: freebsd-xen@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 46795BDABDA for ; Wed, 14 Sep 2016 13:13:12 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 362D21A20 for ; Wed, 14 Sep 2016 13:13:12 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u8EDDCBH052216 for ; Wed, 14 Sep 2016 13:13:12 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-xen@FreeBSD.org Subject: [Bug 212681] I/O is slow for FreeBSD DOMu on XenServer Date: Wed, 14 Sep 2016 13:13:12 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 10.3-RELEASE X-Bugzilla-Keywords: performance X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: daniel@blodan.se X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-xen@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: cc Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-xen@freebsd.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Discussion of the freebsd port to xen - implementation and usage List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 14 Sep 2016 13:13:12 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 Daniel Ylitalo changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |daniel@blodan.se --- Comment #2 from Daniel Ylitalo --- We use XenServer 7 overhere and we can't run FreeBSD vm's on it unfortunate= ly.

This troubles me, as we don't see that - but we are running the test on un-contended local storage (you don't say if you are). The times you show for that last dd run - seem to vary quite a lot: 1342177280 bytes transferred in 22.239869 secs (60350053 bytes/sec) 1342177280 bytes transferred in 38.072567 secs (35253133 bytes/sec) 1342177280 bytes transferred in 5.782933 secs (232092820 bytes/sec) 1342177280 bytes transferred in 7.891797 secs (170072452 bytes/sec) 1342177280 bytes transferred in 12.598706 secs (106532947 bytes/sec) 1342177280 bytes transferred in 7.917661 secs (169516892 bytes/sec) 13421772800 bytes transferred in 147.423047 secs (91042568 bytes/sec) Especially that last one. How busy is the node? / local disks? At this stage I'd be tempted to re-run the tests while on FreeBSD looking at the output of something like: iostat -x 1 (which will show what FreeBSD thinks the disk service time, % busy etc. are= ) - and on Dom0 providing the local storage running: iostat -x 1 | egrep -e "(^Device)|(^sd*)" Which will do the equivalent for Xen. Things to look out for are high % busy, and service time / queue depths. At this point I'm not sure filling the ticket with reams of debug / command output is helping much - it might be better to close this ticket - and reve= rt to email to see if we can narrow things down to a possible cause, before re-opening the ticket again with more specific information. -Karl --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-xen@freebsd.org Thu Sep 15 21:50:57 2016 Return-Path: Delivered-To: freebsd-xen@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 01400BDC644 for ; Thu, 15 Sep 2016 21:50:56 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id D7CB4E26 for ; Thu, 15 Sep 2016 21:50:56 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u8FLou4C032312 for ; Thu, 15 Sep 2016 21:50:56 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-xen@FreeBSD.org Subject: [Bug 212681] I/O is slow for FreeBSD DOMu on XenServer Date: Thu, 15 Sep 2016 21:50:56 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 10.3-RELEASE X-Bugzilla-Keywords: performance X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: rainer@ultra-secure.de X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-xen@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-xen@freebsd.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Discussion of the freebsd port to xen - implementation and usage List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 15 Sep 2016 21:50:57 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #9 from rainer@ultra-secure.de --- I noticed that the local values are very unstable.

I will try to look into this, but it's not going to be now (I hope I will be able to get to it by the end of the month). --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-xen@freebsd.org Fri Sep 16 08:17:29 2016 Return-Path: Delivered-To: freebsd-xen@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 2A89FBD8AC1 for ; Fri, 16 Sep 2016 08:17:29 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mx1.freebsd.org (Postfix) with ESMTPS id 1A432231 for ; Fri, 16 Sep 2016 08:17:29 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u8G8HS3S006187 for ; Fri, 16 Sep 2016 08:17:28 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-xen@FreeBSD.org Subject: [Bug 212681] I/O is slow for FreeBSD DOMu on XenServer Date: Fri, 16 Sep 2016 08:17:29 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 10.3-RELEASE X-Bugzilla-Keywords: performance X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: rainer@ultra-secure.de X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-xen@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-xen@freebsd.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Discussion of the freebsd port to xen - implementation and usage List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 16 Sep 2016 08:17:29 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D212681 --- Comment #16 from rainer@ultra-secure.de --- OK, thanks for the clarification. --=20 You are receiving this mail because: You are the assignee for the bug.=
