The weirdest thing

Postby Raindeer » Thu Jul 22, 2010 2:17 pm

First off thank you for making Cerberus free for personal use. This helped me greatly.

The weird thing I experienced was as follows.

Setup:
Old PC with an Ubuntu Live CD to access the file system and rescue the files on there.
Laptop with Windows 7 on it and Cerberus FTP.
Both connected via UTP to a Linksys 160N
Local connection from 192.168.1.102 to 192.168.1.103
plain simple anonymous FTP straight from Ubuntu --> Connect to Network

Situation:
While sending 10 Gigs from my wifes accounts My documents the average upload speed to the laptop was around 150KBit/s, which is kinda slow on a 100mbit interface. But hey, all those directories need to be made and there seemed to be no other solution, so I waited for almost two hours.

Then did the same with my My documents folder. another 20GB. Same speeds, all rather slow --> half way through wife disconnects laptop from network and browses the net for a while. I come home am unhappy. Find Ubuntu FTP upload doesn't do resume and died on me, taking ubuntu with it more or less.

So I reboot.. Find out what wasn't in sync and start moving some directories that hadn't uploaded yet. With the first directory I get the exact same speeds as before .. its gonna be a long night. Then I decide to upload another directory and see if I can do parallel uploads and if that speeds things up or just halves the speed...

and here the weirdness comes
All of the sudden transfer speeds for both jobs go up to 8Mbyte/sec and more and I whisk 10GB from one system to another in well under 2 minutes.

Was this Ubuntu acting up or was it the server?

Hello,

I can honestly say I have no idea. It sounds like it might be a client issue or something strange with your router/network. I can certainly see slightly higher speeds with multiple downloads (Cerberus isn't always super efficient on non-server operating systems at transferring data) but nothing like what you are describing. Have you tried a different client, or from a different machine?

Sorry, I wasn't able to delve deeper into it. I have been able to confirm the behaviour when I tried it again. However with only two machines in the home, one dead but kept alive by Ubuntu Live CD and one working, there isn't much to go for. I might have a look once I resurrected the dead machine
