Hi all, I'm havng a bareos setup, where I have a bareos-dr/sd on a centos7 VM and I'm trying to backup a folder on a windows 7 PC.
The problem is that the bareos-fd on windows doesn't seem to be able to reach over than 230Mbit/s when spooling data, which looks good, but it isn't if you consider the parameters of the problem. So the facts are: 1. bareos-sd/VM --GElink--switch---10G---Router--...10G network...----Router--10G--switch---GE---WinPC 2. Latency end-2-end is 3-4ms. 3. MTU is 9K and bareos-sd talks with winbareos-fd with a jumbo packets. 4. iperf between the bareosVM and winPC delivers 430Mbps (it is slow). A freeBSD machine reaches 880Mbps with the bareosVM. 5. bareosVM has managed to backup at a rate of 800mbps files from an another CentOS7 host, on the same infrastructure with the bareosVM (0ms latency). 6. A Windows server 2012 with winbareos-fd, on the same infra with bareos (0ms latency), also delivered 230Mbps. So, from 5) I presume that the bareosVM can reach 800Mbps backup speed. from 4) I presume that my network end-2-end can reach at least 800Mbps and I also have jumbo frames. So, why the windows7 PC and the windows 2012 server PC only achieve 230Mbps when spooling data? Has anybody managed to reach more backup speeds of more than 230Mbps when using winbareos-fd as client? Thank you, Spiros PS: I have played with many windows TCP settings, in order to enhance ipv4 TCP performance, with no results. -- You received this message because you are subscribed to the Google Groups "bareos-users" group.
