Poor read performance - 6.5.0 On Ultra 4 Plus

I upgraded to 6.5.0 a while ago, mainly to get the new plex updates, and have read of a slight performance hit, and I expectedthat. However write performance is exceptional, able to write at 100M...

Will test a little later.

Yes both dissabled.

I spoke way too soon, it took me most of the evening to build a windows8 VM.

I attempted a test of speed from an RDP to VMDK via an already provisioned server, Heady heights of 400kbps, and then it stopped after 10 seconds.

If would appear something is preventing NFS from functioning correctly, the fastest I have seen an ESXi host transfer data via NFS peaked at 4mbs.

Again CIFS is crippled whilst NFS is "busy" doing more or less nothing in the grans scheme of things.

(Can you give me info on VMware Certification for the 626x - though I am incredibly hesitant to invest if this cant be resolved).

Finally it appears my VMware cluster is functional again without crippling itself and the rest of the NAS.

Still interested to know performance stats for the 626x however, as this will likely be a pending purchase.

What would you like to know?

I can't test things with my RN626X at the moment as it's tied up at the moment with another project, but I could ask a colleague.

I did test transcoding video using my RN626X and that was a big step up from my 516 which is a big step up from the Pro 6 which is much better than the Ultra 4 Plus. I'm sure you'll love the performance that the RN626X provides.

In the live Q&A recently we were asked:

"what is the difference between Readynas rn626x & RN716X - so the older model actually has more ram, speed but the newer model is cheaper? both 10GB"

The answer was:

RN716X is Intel Xeon Ivy Bridge E3-1265Lv2 2.5GHz (3.5GHz Turbo) Quad Core with 16GB ECC

RN626X is Intel® D-1521 Quad Core 2.4GHz Xeon Server Processor with 8GB DDR4 ECC RAM

The E3-1265Lv2 uses a 22nm manufacturing process, while the D-1521 processor is much newer and uses a 14nm process. The D1521 will operate faster at a lower clock speed.
