Dealing with low bandwidth and folding

post #1 of 6
Thread Starter 
As my points were not accumulating like they should today I checked my log. On two WU's the result was "download error". We just had an update and one WU certainly made its way to Stanford. I have low bandwidth (never over 1.5Mbps) I was also watching YouTube a good bit today. My theory is that there is nothing broken but there was not enough bandwidth to make the download. I had CenturyLink look for errors in their log and none is seen. My next WU is not set to finish for 8 hrs so I will not know until tomorrow how it goes. Any possibility my theory is correct or if not what can cause the "download error" message in my log. Thanks

EDIT: I want to make it clear that I realize the time that my bandwidth is being utilized by a completed WU download can be short (or rather long if it is a big WU). I just want to make it clear I know that your bandwidth is not always being affected by folding.

Doesn't sound too farfetched, I certainly notice when my big rigs are downloading a BA (~30MB), not too often I will notice a normal sized SMP though, a big one of them is 5-10MB. I'm usually above 2 Mbps and my main rigs connection slows way down when I have another rig that's up/downloading. The folding client may have a pretty low network priority and if this is on one rig Youtube may steal all the bits.

Stanfords servers has a timeout for upload (can't remember exactly but I think it's 2h) there may very well be one for download too and if you're running streaming video at the same time you might hit that limit. I'm not sure though

Things seem to be working fine now. I will watch when my finished work is going to be sent and make sure I "clear out of the way". For some reason I only received base points on an 8703 and I did nothing different but be on YouTube. The next 8703 I did I received bonus. I think the easiest explianation is my bandwidth utilization. I notice if I just run my 970 and no gpu work (even just gpu2) my ppd is under 25K. It is getting hard to make points unless you want (and can) invest in more current gear. As we know it is not all about points, but no one likes to see zeros come update time. +rep for helping me figure this out.

EDIT: I spoke with Centurylink about how much I was paying just for 1.5Mbps bandwidth and they agreed to cut my monthly bill in half for 12 months. Suprisingly I can watch Netflicks without issue at 1.5Mbps. Youtube stutters more often than not.

Strange that one 8703 was only given base points and the other bonus. Could have been a problem with the WU from Stanford, idk. If you really wanna find out what's up with that, you have to post over at foldingforum.org to have them check that particular WU.

Having low bandwidth sucks. I have 768k/120k and uploading/downloading absolutely kills my connection. Also arvidab, you're right about the stanford servers having an upload timeout of two hours. It used to be the bane of my existence.

I think my partial credit problems are caused by my poor upload bandwidth. I timed out on the upload of a 6098WU (only 92% was uploaded). I received about 1K over base. More important is how they get the rest of the WU completed. I paid good attention to upload time for the past 3 days and never timed out. This upload caught me by surprise as I was again on YouTube at the time. It is a shame to work the entire 10+ hr. WU (well it is 10+ hrs. for me to work it) and lose out during the upload. I should have made 15,501 on it.
