`<div dir="ltr"><div>Slow CIFS Writes when using Moca 2.0 Adapter.</div><div><br></div><div>I am experiencing this only under OmniOS. I do not see this in Windows or Linux.</div><div><br></div><div>I have a ZFS CIFS share setup which can easily do writes that would saturate a 1GBe connection.</div><div><br></div><div>My problem appears to be related somehow to the interaction between OmniOS and ECB6200 Moca 2.0 adapters.</div><div><br></div><div>1. If I write to my OmniOS CIFS share using ethernet my speeds up/down are around 110 mb/sec - good</div><div><br></div><div>2. If I write to my share using the same source but over the adapter my speeds are around 35mb/sec - problem</div><div><br></div><div>3. If I read from the share using the same device over the adapter my speeds are around 110mb/sec - good</div><div><br></div><div>4. If I setup a share on a Windows machine and write to it from the same source using the adapter the speeds are around 110mb/sec. The Windows machine is actually a VM whos disks are backed by a ZFS NFS share on the same machine</div><div><br></div><div>So basically the issue only takes place when writing to the OmniOS CIFS share using the adapter, if the adapter is not used than the write speed is perfect.</div><div><br></div><div>Any ideas why/how a Moca 2.0 adapter which is just designed to convert an ethernet signal to a coax and back to ethernet would cause issues with writes on OmniOS when the exact same share has no issues when using an actual ethernet connection? More importantly, why is this happening with OmniOS CIFS and not anything else?</div><div><br></div><div>I appreciate any help.</div></div>
