I have a Dell C2100 setup similar to @Mirfster's with 192GB RAM and 12 2TB Seagate Constellation disks. SMB shares are enabled with no customizations. I mounted a /media directory on my Mac did a quick read test through a CAT6 cable on a 5GB file located on the NAS, reading at 106MB/s:
When I transfer a file from NAS to my Mac, the speed is half:
From your perspective, is this considered acceptable? I would like to get close to 90MB/sec transfer speed, if possible.
Code:
$ time dd if=media/file.mkv of=/dev/null bs=8k 590138+1 records in 590138+1 records out 4834417009 bytes transferred in 45.579273 secs (106066128 bytes/sec) real 0m45.796s user 0m0.275s sys 0m5.864s
When I transfer a file from NAS to my Mac, the speed is half:
Code:
$ rsync -a --progress --stats --human-readable media/file.mkv . building file list ... 1 file to consider file.mkv 4.83G 100% 53.29MB/s 0:01:26 (xfer#1, to-check=0/1) Number of files: 1 Number of files transferred: 1 Total file size: 4.83G bytes Total transferred file size: 4.83G bytes Literal data: 4.83G bytes Matched data: 0 bytes File list size: 74 File list generation time: 0.005 seconds File list transfer time: 0.000 seconds Total bytes sent: 4.84G Total bytes received: 42 sent 4.84G bytes received 42 bytes 55.90M bytes/sec total size is 4.83G speedup is 1.00
From your perspective, is this considered acceptable? I would like to get close to 90MB/sec transfer speed, if possible.
