Description

A Freenas Server Fujitsu RX300S6 with 2x4 Core Intel Xeon Prozessor X5640, 98Gb Ram, Intel 10Gb-Ethernet, 12x2TBHDs Raidz-2 with up-to-date Freenas.
Compress and Dedup is on.
Reading with 300Mb/s, writing with up to 220Mb/s. On large files (800Gb vhdx-file) the transfer stopped after a while for 30 to 500s. The transfer is from a windows 2012 server to Freenas via robocopy. With some robocopy adjustments (very low transfer rate and repeat after failure) the file is copied. At the end the transfer rate is in average very very low at 25Mb/s!
the system is doing only backups at the weekend and snapshots. Dedup is important, because of many big vhdx-files (backups from many server).

The CPU is doing nearly nothing (see attachments). The other diagrams I can't interpret.
Thank you for help.
