CIFS shares are slow on HP Microserver

[Milhouse]

now working with the same desktop and doing up and downloads on these systems with a 4gig image file (same file all the case) results:
upload
- freenas : 20-25000kbytes/sec
- win : 90-110kbytes/sec

download
- freenas : 40-55000kbytes/sec
- win : 70-95kbytes/sec

I'd chip in, but your figures don't make sense... you say that FreeNAS is slower? Have you got your kbytes and mbytes mixed up? If you posted figures I could understand or recognise it might help.

I get 55-60Mbytes upload from Win7 to a N36L with FreeNAS 8.3.0-RELEASE (test system), Intel NIC, readahead force enabled, 4GB RAM, 4TB RAIDZ1 (4x1TB). I would expect RAIDZ2 to be slower than this due to the additional overhead.

hi, all thoughts are appreciated.

yes freenas seems much slower. i gave in thousands of kbytes s you could say 20-25M with freenas vs 90-100 with win on up and the other nummbers are down.
since that time i have removed the raid z2 and moved on to
raidz1 - up 26-27M/sec down 50-55M/sec
zfs mirror - up 27-30M/sec down 50-55M/sec
so there is an increase but still it is the third in speed compared to the win host. :-(

made up an ufs mirror too then a zfs mirror with different disk for log then for cache.
so upload went up as max as 35M/sec. wondering whether it is due samba or driver optimization.

hey,

have made up the ftp service.
upload results a very steady 80-90M/s . with which i am ok
download results an even slower 15M/s.

so noobsauce80 my friend i do not think the device is used for something it was not meant for as it is capable to transmit
files up and down with high speed and it is what it is intended to do. So i am looking for ways of tuning regarding cifs share


plus:

as you have advised i have launched iperf as -sD on the freenas and have used iperf for win on the client machine
as following

D:\>iperf -c freenas -P 1 -i 1 -p 5001 -N -l 64K -f m -t 6000 -T 1

which results in the area you have said it shall with a good intel nic.
have found some of your config settings in other thread will try with that.

also i have done dd tests like this:
