I'm running about 380KB/s (a bit more than 3Mb) and its fine. In fact, I have 100Mb LAN that works fine. The bottleneck on the upward limit on network bandwidth is the PCI bus, not the OS. |

It's not Windows so much as TCP with it's error detection, flow control, and windows size.
I top out at 1.4 Mb/sec and rarely see anything over 160Kb/sec not due to my side but due to the other side of the connection. I have been known to download files of 700-800 Mb and the other side rarely give me more than 10-30 Kb/sec. Occassionally I'll update my linux distribution libary and download from universities with huge pipes ... at 100-160 Kb/sec. |

Windows is not your limiting factor, even at gigabit x-fer rates.

PCI bus is 32 bits wide at 33 Mhz which 127.2 Mb/sec in theory. I routinely run video from my hard drive at 16 Mb/sec on my PCI IDE controller without even breaking a sweat. That's almost a T3 connectoin - it is 10 T1 connections worth of data. |

Windows "tops out" at 1.2 Mbit? Uhhh... OK. Now that I know this, I guess my 100MBit ethernet will downgrade to 1.2 Mbit.
The faster your Internet connection, the more likely you'll hit a bottleneck on the other side's Internet connection. For example, running 1.5 Mbit/sec Cable but you only get 10KB/sec download speed from a site. Their connection is slow. I can go to a Windows server in the datacenter and download from somebody with a fast connection (like Microsoft) at 800KB/sec (i.e. 8MBit/sec) and the bottleneck is still probably on our connection. |

Yeah. We ran into this problem at Nortel where our VPN device, which was a glorified PC, could not handle GigE rates because of the 127MB PCI bus limit. Therefore, we had to go to a completely new architecture. Of course, we lost a fortune having to redesign everything and I bailed out a few months before the development team was laid off and the product was shipped to Romainia for sustaining development.  |

I get 496KBps (or just under 5megabits per second) to all major web sites and I'm running WinDoz.
Older, non-XP, versions need to be tweaked. See DLSREPORTS and look for the 'tool' link on the left. You want to run the Tweak Test, which will tell you what you need to do to speed up things. On a Win-ME system, it will almost double your download rate, if your cable company is supplying it to you quick enough. To some extent it also will be impacted by your CPU speed. As a reference, my older 1Ghz box will top out around 3mbps, while a 2.4Ghz will keep up with 5mbps. Good luck! |

I have a 3MB conection and I have gotten up to 1MBps download speeds sometimes. I think it depends on some of your computer factors, but also depends on what condition the lines outside your house are in.

Operating system is not generally a network performance factor at least until you get into the range of 20-50MBytes/sec. Anything will handle a 10 megaBIT/sec connection just fine.

125.9 MB/s, actually. 32 bits = 4 bytes 33*1x10^6 = 3.3x10^7 cycles/sec ~=1.32x10^8 bytes/sec /1048576 byes/megabyte 125.885 MB/sec It's all trivial, though, since actual throughput is much lower. |

Where did you work at Nortel? RTP? I worked at Nortel several years ago (DMS and Meridian products), office was in Richardson. As for windows not handling a 3MB connection, that is nonsense. My cable modem routinely hits just short of 300KB/s and I am running XP Pro. The bottle neck in windows is probably the PCI bus as stated before, and I am not aware of any networking device that does not end up on teh PCI bus inside your computer. |

At the moment I'm using an old P3/751 MHz laptop - 100 MHz front side bus - 512MB 100 MHz SDRAM - running XP/SP1 on a cable system.
I usually exceed 1MB/Sec download speeds. I just downloaded the full XP SP2 (266MB) in 244 seconds (1.08 MB/Sec - 1116 KB/sec transfer rate.) I also ran a speed test on the speakeasy network. 2004-08-21 11:34:09 EST: 8596 / 921 Your download speed : 8802999 bps, or 8596 kbps. A 1074.5 KB/sec transfer rate. Your upload speed : 943396 bps, or 921 kbps |

You were told this by someone who does not have any idea what they are talking about, 3Mb services don’t come close to the top end performance possible with Windows or anything else for that matter. The real limiting factor with a 3Mb service is the servers you are accessing out on the Internet. When you do find servers with enough bandwidth to serve a 3Mb connection it is amazing how fast stuff downloads. But even when doing downloads from bandwidth limited servers the nice thing about 3Mb on your end is you can connect to several different servers and do different downloads at once and still get fast speeds. If the cost difference is not too great the 3Mb will be worth it BUT ONLY if you download a lot of LARGE files. If you don’t download a lot of large files 1.5Mb is more than enough for surfing the Internet. |

BTW, no DSL or Cable provider is offering 3MB service. I've see a few ads from Charter and BellSouth that lie about that. It's an exaggeration by a factor of eight. I just setup my great-nephew's computers on Charter 3Mbps service, and it doesn't "feel" any faster than his old 128kbps ISDN when downloading web pages. The latency is greater with the cable so when you download lots of little images from web sites, the latency rather than the capacity dominates. Of course, when he downloads a file, it is very fast. Most of the work he does is via telnet sessions, so the cable is annoyingly slower than his old 128kbps ISDN. He switched because BellSouth jacked-up the prices on ISDN again. $29/month is a great price. He's paying $15 per month for the first year and will be charged "an unspecified amount" (yes, they actually have that phrase in the contract) after that.z |

fireguy: How much are you paying per month for your connection?
I'm So. Cali-fornia, I'm with Adelphia Cable, my connection speed is to 3 Mbps-down and to 256 Kbps-up according to their website for $40/month. Adelphia has recently started new service with 4 Mbps-down and 512 Kbps-up for $60/month. But as always the actual speeds can vary due to traffic & equipment. I have an AMD 2100 CPU & Windows XP, and I can download at 3.3 Mbps on fast days, and on slow days down to 56Kbps. |

Only if you have a very old PC. Current PCI bus rates of 66MHz and 100MHz are common, and many workstation and server class systems have 64-bit PCI slots. |

There is no exaggeration here about Charters 3Mb service here; latency is also not a problem. I consistently get download speeds 50 to 100 times dial-up. There is no way his 3Mb cable connection should feel like ISDN there is some other problem. I suspect the connection to his house. For downloading web pages 3Mb will not feel that different but when downloading a 200mb file the difference is amazing. |

is that 3 megaBIT or megaBYTE?
If it's bits, TAKE IT. If it's bytes, only take it if you do ALOT of downloading or hosting, because I've honestly very rarely came across servers which even let me download at one megabyte. Edit to add: My ISP used to kick ass before alot of people signed up. I remember downloading from Microsoft at nearly 3 megaBYTES per second... Nowadays I think I'm capped at 10megabits down/1 megabit up. |

What? Do you have a partial T3 or something? 10 Mb would allow you to transfer at over a MB per second. A T1 connection is only 1.54 Mbs... |

I worked on the Contivity VPN product in Boxboro / Billerica. I started just after NT purchased Bay. First two years were awesome as we were still kindof a startup (beer on tap, free food, pool table, etc). Then it all went to shit when corp found out that we were having fun and being productive. Corperate bitches. I hope I have that kind of opportunity again. |

Nope.. I got my cable modem before they shipped them pre-capped. It's a Motorolla SB4100, with 38mbps symmetrical up/down. I used to get REALLY good speed out of it, and I mean REALLY good speed. Now I've got a mixture of ISP-side speed reduction and a router with 3 computers on it, which further reduces speed. No complaints, though. I just downloaded Asherons Call 2 to check it out off of Gigex.com- Average speed was around 5500kbps. Not what I could be getting, but still pretty good by any standard

I'm using a five year old Gateway PII 450MHz machine with 256MB of RAM and have a Charter 3Mb cable connection going through a Linksys router with Windows 98 as the OS.
When I upgraded from the 2Mb they had before, I actually saw a drop in speed for a few days until I made a huge deal about it with their "customer service" people. After a few tweaks on my computer and them doing whatever the hell it is they did, my speed went back up. Checking my speed on various test sites, my nominal download speed is around 2.7Mb/s and when downloading files I usually do so at around 200Kb/s. Sometimes faster, sometimes slower depending on the server I'm connecting to. |
