Readynas 6 Jumbo frames optimization, SMB versions OS4 & OS6
I have a ReadyPRO 6 that I got last month instead of my previous Ultra 6 that got funky when restarting it. (thanks to extended warranty). I had previously the infrant NV's variants since the company ...
I just did a factory default so I made some tests on my legacy Ultra 2 under 6.1.6 with either a Win8.1 (M4 128GB SSD) or a MBA 13’’ (SSD & thunderbolt ethernet adapter). Windows was used for CIFS/SMB test and the OS X Maverick for AFP and samba (smb2). All were tested with drag and drop method with each time 2 different files around 8GiB size (like Netgear did for http://www.readynas.com/?page_id=3962) and there wasn’t any significant speed difference between the 2 files.
I used my Ultra 2 for 18 month under RAIDiator 4.2, and at that time it had samsung 2TB 3 platters F4 ecogreen : HD204UI minimum speed is the same for read & write at 62MB/sec. Now for OS 6.1.6 I have Toshiba 3TB 3 platters DT01ABA300 which read & write speed is at minimum 75MB/s.
Therefore the readyNAS was completely empty for the purpose of those tests.
Bandwidth speeds will be written in MiB/sec (for 1 to 3 minutes total time of copy) to avoid artificially increasing the speed compare to Netgear’s numbers (some may know that windows indicate size to be GB but in fact it’s GiB). As I said I made 2 test for each speed to have a vague idea of speed comparison for os4 / os6 and also for Jumbo frames which were set at 9K (http://www.mylesgray.com/hardware/test- ... s-working/)
1) CIFS drag & drop MTU@1500
read = 108 MiB/sec
write = 84-85 MiB/sec
2) CIFS drag & drop with Jumbo Frames at 9000
read = 111-114 MiB/sec
write = 105-107 MiB/sec
3) AFP drag & drop MTU@1500
read = 105-107 MiB/sec
write = 84-85 MiB/sec
4) AFP drag & drop with Jumbo Frames at 9000
read = 109-116 MiB/sec
write = 100-101 MiB/sec
5) SMB2 drag & drop on Mavericks with 9K Jumbo Frames
read = 103-104 MiB/sec
write = 102-104 MiB/sec
In the end you can see the increased speed from RAIDiator 4.2 to readyNAS 6.1 ! Even for a very low speed atom (Pineview D405 @ 1.50GHz). You can also see that AFP is now nearly at the speed of SMB. And in the end Jumbo frames are giving a little extra boost to reach the 100+ MiB/sec. close to the maximum for gigabit. Keep in mind that it's best case scenario, and the more you fill your NAS with data, and move data often, the less you can observe those maximum speed.
Note: for mac os x users : even if you can apply jumbo frames in networking settings and still have ethernet connection, you need to reboot !! Otherwise you'll end up with only 40MiB/s speed s compare to the 100MiB/s. I also didn't tried iSCSI,
