Hi all, I am now in Collingwood, Ontario and I went with Rogers cable instead of DSL internet at home (ADSL is in Alberta and is much better than DSL in ontario) So my question is does OSX have sysem hacks to increase bandwidth?? even by alittle bit? and is 2.6 Mbits dload a second decent?? I think it's better than ADSL for sure! thanks for the info...cheers, Mark

I would say 2.6Mbps is pretty good considering cable is capped at 3Mbps.

I have always used Rogers and consistently get good bandwidth - usually better than my friends using DSL. I don't know what the standard bit rate is for DSL though?

I was wondering about this same thing as I was only getting 2.0 Mbits with Rogers HS. I was able to open it up a bit and I am now getting 2.9 Mbits w/ some variances (2.6 through 2.9) I am quite happy with that. As of this time it remains constant at 2.9... [img]smile.gif[/img]

Must just be Rogers that's capped at 3Mbps. I regularly hit 5-7 Mb/s without problems on Shaw.

That's interesting - what are you using to measure your throughput? According to CNet Shaw averages 1.2Mbps (one-way) on average compared to Rogers' .9ish Mbps.

You must have Hi-Speed Extreme-I that allows 5Mbps downloads? They don't offer that in Ontario. I have the hi-speed for Tele-Commuting through my company with Rogers which ups the bandwidth to a full 3Mbps download.

Using Ethereal on my win box I see regular rates of 2.9ish. I haven't measured my Mac but I figure it's probably the same.

If you want a hack for os X to make it faster there is one, It increases the incomping page file size so os x will download and store more information coming from the internet. Its along the same lines as carl with the mtu issue but instead of allowing larger packets this deals in total information store locally. I would recomend alot of ram. I have been looking for this on the internet but cant find it. I know I have it in a macaddict magazine. I will try to find it and post it.

RC51Pilot - When I was back in Calgary, 5-7 was common place on a normal Cable modem for me. I think it may be because it is a) Shaw and b) Calgary which is the home of Shaw Communications.

CNet's stats are based on submissions, so I'm not sure if that makes a difference, but I've never reached 1.2Mbps except maybe 5:00PM Sunday evening a few years ago.

I usually test the connection at DSLReports.com, but I've also used the Shaw test (which is not a real world test). Shaw only has two speeds, normal and lite.
