hi i have 2 unraid servers

both have 7200rpm drives.. both connected  to 1gb network     when using rsync  all im getting is  35meg/s copying of 1-3gb files    i not getting the 100-120meg/s  i get from my desktop to the server..   i only noticed as i doing command line rsync   

is there a way to see whats bottle necking or is that part of rsync slower then  regular  copy from windows to the array  or copy from the array to the desktop

 

but if its not possible thats ok  i figured i could get same speed as windows to unraid   

and i dont use  a cache ssd  as i dont wanna wear them out for copying .. so its direct copy  hard drive to hard drive   over the network

Do either have parity?

ya  the main server has parity..   but im copying to the other unraid  which has no parity   and it fluxuates  25meg up to 45 meg  but wont go higher..  

 

when i copy from Windows  to the Main Unraid server with parity i will get anywhere 90-120megs/s  

so  i figured maybe rsync is a slow process over windows copy

What is the rsync command? Some options can slow things down.

echo "Backing up Videos"

rsync -avzu --exclude ".Recycle.Bin/" -s --stats --numeric-ids --progress -e "ssh -i /root/.ssh/id_rsa -T -o Compression=no -x" /mnt/user/Videos/ root@backupserver:/mnt/user/Videos/ --delete

i dont even know what half all that means i added some code from other peoples when i googled and modeded to what i needed 

-z does compression, which actually slows things down if you already have a fast connection.

ok ill remove it   and try again..  so it compresses the files?

 

so it got me up to 50-70megs not the 90-120meg mark but least its faster then before lol

Yes, which is helpful if you have a slow connection, but just takes extra time to compress/decompress if your connection is already fast. Mostly would be used if transferring files over the internet.

ah ok cool cool.. anything eles in the rsync thats keeping it slow  or thats just how it is  rsync  slower then normal copy...  but least its faster as it was like watching paint dry lol

get 2 10gb Network cards and copy between servers

i can do that...  can you have 2 10gb nics  linked each other with i guess a cross over cable.. and then have the other nic attached to the network..

i wanted to get a 10gb network switch.. the cards are affordable i but when i seen a network switch  i couldnt believe the prices
