For a few hours, I've been experiencing a problem with uploading finished tasks: the upload speed which is normally between 500 and 600 KBps, now varies between 20 KBps and almost zero. The upload of about 50% of a Gianni WU (181MB size) has been running for almost 80 minutes now.

A test of my system has shown that the internet connection is okay and on full speed.

What's the problem?

The uploads and downloads are probably being slowed by the bandwidth of the Adria OPEN and CLOSED tasks downloading, failing right away, then reporting failed. Bad task batches currently. Need to just wait this out until they are removed again.

this might be the explanation. I, too, am receiving these Adria WUs on all of my hosts; no idea what they are not being removed from the server.

Uploading a work unit, 145MiB, speed varies between 1mbit/s and 10 kilobit/sec.
In packet capture we see a lot of TCP re-transmission and duplicate ACKs (may get 90 or more in a row, one time 360?!). 450MiB of data was sent from our side, just to upload this 145MiB file.

I was thinking of writing to my ISP about their lousy connectivity to Europe, but when I looked at traceroute and ping for the server I see no evidence of loss or bandwidth saturation in the network path. e.g. while the upload was 'slow'...

$ ping -qc 50 84.89.134.145
--- 84.89.134.145 ping statistics ---
50 packets transmitted, 50 received, 0% packet loss, time 49056ms
rtt min/avg/max/mdev = 370.399/371.614/373.334/0.616 ms


Is there a problem currently at the server side, or could it be something else I have overlooked. Are others having troubles uploading WUs?

again, I see extremely slow uploads today; many times, they even pause for a while.

Is anyone else making the same experience?
