I''m using HFSC to limit bandwidth for our wireless customers. However, I''d also like the bandwidth prioritized based on packet type. This is what I''m trying right now, and I''d just like some input from anyone out there knowledgeable in this on whether it does what I want it to do: Eth1 -> HFSC ........|-> HFSC (User1) (Min 512 Kb, Max 1024 Kb, Burst 1536

...d packet shaper (using tc / tcng''s tcc compiler) to shape a large amount of inbound and outbound traffic to my data center. Whilst I can perform shaping functions using HTB, I need to also provide an absolute (to the nearest few 100kb/s) bandwidth usage maximum. As an example I might have 200MBit/sec "agreed" bandwidth, and the ability to go up to 500MBit/sec if I wish. Anything past 200MBit/sec invokes a huge cost. Example tcc script (might contain typos): dev eth0 { ingress { $inpolicer = SLB ( cbs 100kB, cir 200Mbps ); class (<$whatever>) if SLB_ok ($policer);...

Hi, I am running two hosts with xen-4.0.1 and dom0 kernel 2.6.32.41. The two hosts are connected to a Gigbit switch. Then I use iperf to measure the bandwidth and got the results of 200Mbit/second, which is only 1/5 of the available bandwidth. Then I boot these two hosts using a vanilla kernel of 2.6.32.34. The iperf reports 937Mbis/s, which is very close to the available link bandwidth. So why the pvops dom0 kernel performs so bad? Does anyone observe similar problem? Thanks. - Hui...

Hi I installed the following driver. http://www.f.csce.kyushu-u.ac.jp/~shigeaki//software/freebsd-nfe.html Before I had the nve driver which was unstable on this server and on a prior server in both cases causing either spontaneous reboot or just a crash when under load. So far touchwood the nfe driver has stayed up and running at almost 3 days uptime and has had some stress. I know the driver

The problem is when I do that, the program is us= ing ~8% cpu on a 3.2ghz xeon64 just reading packets without doing anything = due to the amount of traffic passing through the box (~200mbit and increasi= ng) so that doesn't look like a good idea. brctl showmacs returns a list of port numbers, but they dont make much sens= e to me.

Hey everyone, I had a question about the class id''s using the TC command. I''m using a command that looks something like this: tc class add dev eth1 parent 10: classid 10:$variable cbq bandwidth 200Mbit rate 512Kbit allot 1514 prio 5 maxburst 20 avpkt 1000 bounded That''s just an example. My problem is I''m guessing the $variable is not allowed to be anything over 9999. I''m getting an error when I run that command with anything over 4 digits as a $variable. The error is:...

...a client limit of 20, since I figure that proxying is a lot more work than just doing IMAP logins. I'm doing auth to mysql at both stages (at the proxy level and at the backend level). On a sample director box, I've got 10000 imap connections, varying from 50mbit/sec to the backends up to 200mbit/sec. About a third of the connections are TLS, if that makes a diff. That's pretty normal from what I've seen. The director servers are usually 90-95% idle. Should I be able to handle a much higher client_limit for imap-login and pop3-login than 20?

Hi Maybe my problem is litle offtopic to this list , but maybe someone had something similar like this , and have some good solution . Ok, I''ve have router with four intel e1000 pci-x(2x100Mhz/2x133Mhz) nics that push about 200Mbit/s , and I''m using nload for realtime traffic monitoring. Everything was great until I''ve updated kernel to 2.6.17.13 . After update nload is showing some crazy values . I''ve tried to get counters from /proc/net/dev (like nload). root@kaermorhen:~# while true; do ca...

Hello! One simple question regaring htb2->htb3 way. I''m using 2.4.25 kernel with tc3 from Devik''s site, RH9. My data flow is about 100Mbit duplex and is subject to grow, so I''m creating root class with 200Mbit rate, with r2q=10, quantum = rate/r2q, and 1500 < quantum < 200000 (sch_htb.c) with such r2q my default shaping window will be from 120Kbit to 16Mbit, right? So, the question is choosing r2q=10 -> max bandwith for root class=16M, or it affects only leafs? -- Michael Vasilenko ________...

...15898 --> https://bugzilla.samba.org/attachment.cgi?id=15898&action=edit zstd support zstd compression was announced as "good compression with high throughput" so I gave it a try. With zlib, on high speed links the CPU is usually the bottle neck. With zstd I'm able to fill a 200Mbit link :) zstd detection happens automatically via pkg-config. No zstd header means no error about missing zstd. So that should be okay. However, pkg-config is now kind of required? I duplicated the zlib code and replaced it with zstd hooks once I understood what was going on. I made a few local te...

I added ZSTD support to OpenSSH roughly over a year and I've been playing with it ever since. The nice part is that ZSTD achieves reasonable compression (like zlib) but consumes little CPU so it is unlikely that compression becomes the bottle neck of a transfer. The compression overhead (CPU) is negligible even when uncompressed data is tunneled over the SSH connection (SOCKS proxy, port

Hi all after being a silent reader for some time and not very successful in getting good performance out of our test set-up, I'm finally getting to the list with questions. Right now, we are operating a web server serving out 4MB files for a distributed computing project. Data is requested from all over the world at a rate of about 650k to 800k downloads a day.
