Hi Spiros, i think that your problem consists of more factors. One is your PC's harddisk. A single dedicated SATAII (for example seagate baracuda ST3000DM001) has an avarage read performance of 156 MB/s. So you are limited that way. The Bareos FD have to read the files, process them and transmitting it with its own protocol. A GE Ethernet means you can not transmit more than 125 MB/s in theory. Your iperf if i understand it tells you that you have transferred 430 mega bit per second? mbps .. Thats only 53,75 Mega Byte per second and iperf tests are mostly a bit faster than file transfer in real life ... So the functional chain is long, Bareos FD, HDD, Switch, Protocols, Bareos SD, Serverdisks, Drivers on windows and linux till down the Nagle algorithm which is not good implemented in every operating system and many more.
Yes 30 MB/s is slow but to optimize your setup you have to do deep performance analysis on every part that is involved.. Did you ever have done a simple file copy test from the PC to an fileserver? Is the performance much betterß Regards, Marco On Wednesday, September 23, 2015 at 8:21:52 PM UTC+2, Spiros Papageorgiou wrote: > Hi Marco, > > The win7, is my desktop PC and it is physical.
