Hi again. 

I don't know if the problem is vmware plugin, but it looks like.

My enviroment is a vmware cluster and, on the other hand, one server with 
Proxmox VE running bareos director and bareos storages and only this. This 
server has 24 x Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz (2 Sockets) and 
64GB RAM.

When i do the backups, all works fine, but the transfer rate is so poor, 
about 300kB/s. I do iperf tests and all works fine on my network and disks.

I try everything that my brain permits:

- With data spooling. without.
- Mounting disks with noatime
- Changing encription
- Changing compression to all types
- Without compression: Here we go, without compression, transfer rate ups 
to acceptable values (40-50MB/s). I thought could be the CPU performance, 
as obvious, so i put many cores and RAM to the machine with no results. 
(Later i discover that compression is done only for 1 CPU in any case). 
Then, i tried to move the client to the vmware cluster, because is more 
powerful. No results. Then, I moved the entire director with no results 
either.
- I try with a Windows client, without vmware plugin: With compression, the 
transfer rate is about 12MB/s. Isn't the best, but better.

I have to say i have others bareos virtualized enviroments with correct 
performance.
Other thing is breaking my brain, is: when the backup starts, starts about 
20MB/s (seconds) and is going down until stands on 300KB/s, like a 
buffering problem or bottle neck, but i don't find where.

I'm desperate... Anybody can recommend something else to check??
