| I've had a huge slowdown in uploads since the end of January. There are many possible causes, but I have to say, it's really odd when you do speedtests and get 14,000 kbps download (they used to be about 5000 so they have tweaked something) and the upload is 18kbps (when you're lucky... it's actually blipped below 1 on more than a few occasions) Watching FTP in progress, or using net diagnostics you can actually see the slow down from slow to REALLY SLOW to ... practically not moving at all. I dont think it has to do with the Mac specifically, but it's possible, I guess. The downloads are also being interrupted by an intermittent staccato, so it's a pop pop pop kind of thing, not a steady flow of data. You can literally see it in Cyberduck, for example, as the FTP is 'progressing'. I'm using macbook pro 2.3 and an airport express. Without the router the download speeds are a little faster, but the upload is still crippled. Just tried adding the apple broadband 'fix' and I see no noticeable difference. It was supposed to increase the limits on the buffer (?) My downloads start fast and are at least passable, since more likely the actual speed downloading is closer to 5 or 6000 sustained) ... and then upload chokes. Every now and then it comes back to close to 300 (where it belongs) so I seriously doubt it's a modem, or a Mac OS problem... You may be experiencing the same thing. I think it's a comcast issue. You might want to check your modem - if you have a motorola you may need to get a configuration fix ... the updates that comcast is sending are not the right flavor for the modem and error messages show up in the log. Can't say if that 'fix' will help or not... I've requested a ticket but I'm still waiting for mine). It might be worth checking your modem log to see if that's happening to you. Meanwhile, if anyone has any ideas about how to tweak settings to enhance the upload speed, I'd love to hear about it ... Thanks! (using 10.4.8) |
