Data Transfer Speed
I've run several tests at different priority levels and connections speeds and don't see much of a difference in the time it takes to back up a 1GB file as a function of the connection speed setting. Priority seems to make difference depending on what other processes are running on the machine. The range of times was from 1min 30 sec to 4 min 30 sec with the longer time at the low priority and the faster time at high.
Transfer rates from my PC to my ReadyNAS using IOmeter are slow with 10MB/s writes. Does this explain why the connection speed setting in ATI does not make a difference?
Also, I see a huge difference between the estimated time the ATI reports and the actual time - typically on the order of 2x. I ran one backup of 100GB of data that ATI reported was going to take 21 hours and it took 4. This sounds like a bug in the program.
For large backups I'm seeing the estimate hold until the end and be off by a factor of 5. Such as an estimate of 20 hours and the actual of 4 hours.
I'm more interested in why I'm not seeing any difference with the connection speed setting in ATI. Does anyone else see this?
The slow speed is probably why the setting isn't making a difference.
What speed is the network connection? What speed is the NAS? If they are both Gigabit, the speed should be much faster.
Not hardly gigabit. Using IOMeter, I'm seeing 10MB/s writes to the NAS from my PC.
How ATI calculates its estimated times is a mystery to me! and I take no notice of them usually - experience of how the values alter as it goes along tell me enough to know things are working and I can make my own estimates. I doubt it looks at priority levels though because they are only used by Windows when processes are competing for CPU time, it more likely assesses the speed its own process cycles are taking rather than bothering with what the competition is doing.
