(Solved) - Improve network speed over lan

[Harald654]

Hello,

I use my RPi2 as a network drive to access music/movies and save backups via SMB. Since the Rpi2 with 100Mbit-Lan and USB2 speed is very limited, for me therefore counts every bit/s.
With Raspbian and other distributions i always get a network speed of about 11-12MB/s(read/write) over SMB, with xbian however only 8-9MB/s(read) and 4-5MB/s(write).
Because as i said for me every bit/s counts, i wanted to switch to a Gbit-lan adapter. Since everything runs over a single USB controller, i expected no huge speedup, but with Raspbian or OSMC i reach a speed of 16MB/s(read) and 12-13MB/s(write) over SMB with the Adapter. With Xbian unfortunately i get again only asignificantly lower speed of 12MB/s(read) and 6-7MB/s(write):

-i testet the Speed with a fresh isntalled Xbian on a sandisk ultra 32GB SD Card.
-The values in the test are based on the informations of the Windows Explorer when reading and writing a 2Gb large ISO file (film) on the external HDD (ntfs)
-With my USB stick (ext4) the speeds ar minimally higher, but the ratio are the same.
-Is noticeable that with xbian at the start sometimes the reading speeds is as high as with OSMC (12MB/s) but after a while it breaks down to 8MB/s (like you cann see at the picture of Xian-write-100Mbit)
-same result with overclocking to 1100 Mhz

My Enviromet:
-PC and RPi2 connectet via Lan with my Gbit-Router (Unitmedian) an Cat6 cable.
-PC: I5 with Gbit-Lan and SSD (Windows 10).
-Hard Disks Pi2: Western Digital 4TB My Book-USB3-ntfs / SanDisk Extreme-USB3-ext4
-Sd Card Pi2: SanDisk Ultra 32GB

My question is now, does someone knows what the lower speeds with Xbian lie and is there a possibility to increase the network speed? (At least the same speed as with Raspbian or OSMC should be possible i think?)
