Hi zfs-discuss, I have some questions about throttling on ZFS 1) I know that throttling is activating while one sync is waiting for another. (http://blogs.sun.com/roller/page/roch?entry=the_dynamics_of_zfs) Is it possible to throttle only selected processes (e.g. nfsd) ? 2) How can I obtain some statistics about it? I want to know how often throttlin...

...o change block I/O throttle using 'virsh blkdeviotune' with vm not running, it reported an error: # virsh blkdeviotune instance-000000dc /dev/loop0 --total-bytes-sec 20000000 --total-iops-sec 20 --config error: Unable to change block I/O throttle error: unsupported configuration: block I/O throttling not supported with this QEMU binary I can do this when the vm is running. Is it a bug? How can I fix this problem. BTW,My libvirt version is 0.9.13: # virsh version Compiled against library: libvir 0.9.13 Using library: libvir 0.9.13 Using API: QEMU 0.9.13 Running hypervisor: QEMU 1.1.2 Thanks....

Hi, we bought some machines with 2 x quad core Xeon E5405 processors and installed centos 5.3 on them. My problem is that I can't get the cpuspeed service to work. No driver seems to claim responsibility for the throttling and the fallback "modprobe acpi_cpufreq" in the cpuspeed init script just yields a "No such device" message. According to the acpi information the CPUs should support this just fine: cat /proc/acpi/processor/CPU0/info: processor id: 0 acpi id: 0 bu...

Hello All, I was recently fighting with an optimum online connection in NY. I finally got in touch with someone that confirmed they are throttling my upload connection. I just wanted to make everyone aware of it, so if you have problems if your ping times jump erratically, this could be the cause. Their suggestions were, although you can upload a lot, do not do it constantly. They do not want any constant outgoing connections. Even on bus...

I have updated my laptop to 7.4 CR this morning and found that there have been a lot of logs on two fronts for the first time. 1. The kernel has indicated overheating: [Sat Aug 26 08:58:21 2017] CPU2: Core temperature above threshold, cpu clock throttled (total events = 1) [Sat Aug 26 08:58:21 2017] CPU4: Package temperature above threshold, cpu clock throttled (total events = 1) [Sat Aug 26

I have a small, aircooled pc server, which is running fine, but the log gets filled with a series of messages saying the package, and each of 8 cpus is throttled because of thermal issues. Then, within the same second according to the timestamps, it reports everything is OK and throttling is off. This happens once every minute. In reality, when I try performance tests, I believe the processor is actually spending measurable time in the throttled condition. I have installed lmsensors, and am monitoring temps as frequently as the reported throttling occurs, but I never see any hig...

I hope this list is still active. I''m an experienced Linux Sysadmin, but I haven''t done much in the way of routing. Due to a decision made by my higherups, I need to jam a computer between my ISP and my LAN to do bandwidth throttling. My current setup: 1 Crappy Cable Modem (7Mb/768Kb connection) with a static IP. 4 servers (all have static, routable IPs) - One of which is running NAT/DHCP (2 NICs) for 6 workstations (All using DHCP) I have 1 spare routable IP. My current setup has the cable modem plugged directly into my LA...

mhh - interesting question...... what about combining the power of throttle ( http://linux.die.net/man/1/throttle ) or similar tools (there are some more like this) with rsync ? via this hint: http://lists.samba.org/archive/rsync/2006-February/014623.html i got a clue how to combine rsync and throttle and gave it a try : cat throttle-wrap #!/bin/bash throttle -k 1 -s 1| "$@" rsync

Also try package lm_sensors and its command sensors-detect, maybe just the temperature sensors are not properly initialized On Sat, Aug 26, 2017 at 8:42 PM, <mad.scientist.at.large at tutanota.com> wrote: > It means it's time to open up your' laptop and evict all the dust > bunnies. it's overheating on one desktop but not the other because one of > your' desktops,

All, Is anyone using iptables (recent module), or any other alternatives, to throttle the number of new imap or pop connections per minute? We have some applications that like to login every second to pull mail using imap, so we'd like to protect the entire dovecot server from these applications. We've already made the change over to high-perf mode, but we still need some type of denial

Hello I am having a hard time with users using POP while leaving mailboxes of several gigabyte cumulated. This causes a lot of disk I/O and kills performancs for everyone. I try to encourage people migrating to IMAP, but that migration will take some time, and therefore I am looking for alterantive ways to workaround the problem. I found pop3-throttle-plugin.c, which seems a smart way to solve

Hi Everyone, This is a simple question but I don''t understand why the below tbf is not working as expected by throttling traffic to 5kbps If I throttle a PC''s traffic using the below when traffic exceeds 5kbps packets start getting dropped (as they should) but all traffic gets dropped. not just the bit over 5kbps. TC="tc add dev ppp0" $TC parent 8001:2 handle 2: tbf rate 5kbps latency 50ms burs...

I know this will be trivial for most, but I am having trouble with getting my scenario to work correctly. I want to ''tag'' and ''throttle'' the bandwidth to and from a particular client on my lan side. Better yet, I just want to throttle smtp traffic, per say, for that ip. ----lan----------eth1-[linux.box]-eth0----------internet I have used the technique
