I'm afraid I cannot answer your questions about your network, I was merely suggesting you consider that unless you can prove that you can get faster performance from other tools on the same infrastructure. Problems like this are very difficult to isolate and people generally don't consider the most obvious reasons for why performance may not be what is expected.
If 1.5MB/s is 1.5 mega bytes per second, your network speed is not very fast. If it is mega bits per second, it is even worse. You also have to consider your source and target dbs' upload and download bandwiths AND if anyone else is using your network for anything else at the same time.
As an example of how location can affect performance. I was on a project where I was running Talend on an internal network where the performance was reasonable (I cannot remember the number of rows per second). I went off site and ran the same code in a different country. The performance went down by a factor of around 20. The data had to be retrieved from my source db over the internet to my laptop, processed and then sent back to the target db over the internet. The latency caused was massive. You need to consider this before assuming there is anything wrong with the job
