I'm curious what others with good upload bandwidth are currently seeing for their CEP upload rates and times. I am specifically interested in the results for those with a 5Mb or greater upstream bandwidth connection.
----------------------------------------Through my current ISP, I have a relatively low 1.5 upstream rate. Average uploads: 175K speed (per BOINC transfers tab) @ 4 minutes for the ~40 Mb file.

The closer you're to Harvard, the faster it will likely go. From here, in the Italian outback there's too many hops. Have measured 1Mb up, but CEP2 just tops out at 80K. But to Toronto, where the WCG servers are hosted, it's substantially faster. No idea why... some have speculated on there being throttling in place. Could be my bloody ISP is doing this when it gets to transport a zip file. It does not bother me in the least, simply because my connection not ever gets to saturation point. But, if you have a farm crunching CEP2, then it could become a problem... not enough hours in the day to upload all completing work at 80Kb.

I am supposed to have 1.5m down and 750k up, but I rarely if ever see that. A cep2 upload takes from 20 to 30 minutes from me.

That's a good point... to the T was practically always around 7 minutes when the _4 was at 30MB size [is that about 96Kb mean speed?]. With the current 40MB it will be getting to 10 minutes.

My ISP gives me 8Mb download and avg 83.5kb upload. I am expecting faster speeds when BT get Fibre to Cabinet later this year, it is a semi-rural area here so will not be getting Fibre to the Home. Expected speeds will be 24Mb download and 1.5 Mb upload.

This is why I don't do more CEP2. My wife starts complaining about her "computer being too slow." With the limited number of projects we now have I would put CEP2 on 40 cores but I don't have the bandwith. |

AT&T just retrofitted Uverse into our neighborhood. We have fibre into the neighborhood box then they are using two pair of copper from the nieghborhood box to my house.
----------------------------------------Today I am getting 15.84 Mbps download and 1.44 Mbps upload. Just a few minutes ago CEP2 uploaded a job and it ran at 177 KBps. Looks like the uploads of ~40MB are taking ~4 minutes. Not as fast as PecosRiverM's Fios, but far better than the DSL that we used to have.

From Texas to Hartford Can you please post your experienced CEP upload rates and time as well? This is really the upload rates (and better) I am exploring now. I am interested in how it transfers to the CEP upload rate. I'm expecting some limitation on the receiving server side. Thanks -Paul
