Re: [WISPA] Can't get my 100MB
Lots of possibilities First, you need to find a method of testing other than public web test sites like speedtest.net and speakeasy.net. You will not be able to narrow it down conclusively, without having control of variables on both sides of a test path. Second, we found www.visualware.com (myspeed.visualware.com) to be a helpful site to gather more data, to identify link problems. Their IT staff was able to provide us custom reports on various links stats taht were not normal for a link. (such as grapghs of pause and loss and retransmits and such). Third, Make sure Flow Control is set correctly on ALL ETHERNET SWITCH devices inline. Switch to PC is supposed to be FC ON, and Switch to Switch or Radio to Switch FC is supposed to be OFF. Sometimes this can be set wrong on the upstream providers switch also. If set wrong, not uncommon to get 50% degregation of speed or more. Fourth, Make Sure Duplex is set correctly. MANY CISCO routers do NOT auto detect correctly with other Switches. OFTEN we recommend hard setting 100mb FDX (auto neg off) on both the Cisco and the device coonnected to the Cisco. If this is set wrong, expect to get atleast 50% degregation of speed, and likely worse speed in one direction. Fifth, REMEMBER TCP AUTOMATICALLY slows itself down, if it false detects congestion, pause, or packet loss. REMEMBER the forumla for window size times latency that equal max transfer rate possible. That means... a 100mb link with 5ms accross town might do 95mbps, but 100mb link across USA at 70ms might do 5-10mbps. When running TCP at standard Ethernet 1500 byte packets, you will be harmed by ETHERNET distance (latency) TCP slow down. Also, Window size issupposed to auto adjust with Windows in most cases, but it always doesn't. So when runing a test, its important to recogbnize whether the correct window size gets adjusted during the test. (Inold dats 64kb window was the largest, but now PCs can multiple that by another number, so window size can be much higher. 64kb x X=widnows size. I can remember the max but its in the 700kb range I think. Anyway two things come out of that... A) USe a low latency path for your test, to test your circuit, otehrwise you are testing the Internet transit path. B) Use a UDP testing tool, to verify whether the capacity is truly there or not, so TCP slowdown (nagel augorythm?) is bypassed. IF UDP can do full capacity, then you know its not a capacity issue, but instead of link quality issue. C) USe a TCP multiple PArallel stream tests. For example, if you get qty 10 of 10mbps streams it means you have 100mbps of cpaacity, even if teh top speed you can achieve individually is 10mbps. Again, if the combined speed of multiple tests is a greater value than the speed of a single stream test, again, you likely have a link quality issue. Sixth, IPERF JPERF is your friend. It will help you get the data that you need. Its supports TCP/UDP/PARALLEL streams/MULTIPLE WINDOW SIZE. Try and talk your upstream into deploying a Iperf Server. Many carruiers are starting to standardize on it, for testing ONNet Ethernet circuits. Seventh- Do NOT trust Mikrotik routing to be able to deliver full 100mbps speeds. Dependong on your routing configuration, you can get huge limits. In some cases we've seen the Mikrotik result in speeds as low as 10-15mbps max transfer when on a 100mbps link, but then a change in routing config allowed us to get almost 80mbps. Eighth- Dont tryust your laptops to test full speed just because it has a Gigbit port. Laptop chipsets can cause delays. Sometimes its a good idea to test a secnd laptop to see if you get the same results. When its a problem it usually has something to do with NIC buffers and such, where it may be effected only in one direction. For example, not enough receive or transmit buffers. Or poor NIC drivers unable to do DMA transfers and stuff like that. NINETH, AFter you test yout test tools then you can test your links. Remember... PAcket loss and delay is accumlative over the whole path. And in aggregate it may have a worse result. For example, Lets say we have two Links A and B. If link A has packetloss of 1% and linkB has packetloss of 1%, in combination togeather, the loss might not be 2%. It might be much worse like 5% in combination. The same thing applies to speed. If link A tests 50mbps, and linkB tests 50mbps, does NOT MEAN that a PATH COMPRISING Link A and B in combination will yield 50mbps. The reason is that the loss can be accumulative accross the agregated path, and exceed some threshold, that tells TCP's nagel algorythm to slow down. The TCP automatic congestion control and slow down will be the primary cause of link slow down. Remember TCP was designed to think that packet loss and delay is caused by congestion, so if you slow transfers down, the packetloss and delay will go away, so it is programed to keep slowing down until it is gone.

Re: [WISPA] Can't get my 100MB
I've found the best way to achieve a links true full potential is to use Bittorrent. Share some *nix ISOs with the world.

Keep in mind, you need beefy systems to be able to generate, sustained amount of 100meg bandwidth, for testing.

Re: [WISPA] Can't get my 100MB
As an aside, the packet pushers podcast is really quite good. I especially enjoy Ivan P. And I concur that nowadays turning off autoneg results in more half-dup connections than it does solve problem. Fwiw, I still lock redline-cisco links.

Re: [WISPA] Can't get my 100MB
I can break my fiber connection by turning on auto neg every time. Thats on a Dell managed switch.
