slow transfer speed 10GB
I have 2 nas devices, one synology and the other is a qnap, both have 10GB nic's. They are both connected to gs110mx switch. From my pc to nas is get 110/MB on both nas devices but if i transfer from one nas to other i get 60/MB/s. Both nas devices are 8 drive raid-6 with ssd cache on both,ts-873(32gb ram) with qm2-2p10g1t 10gb nic and DS1821+(36GB ram) with E10G18-T1 10GB nic
but i need to buy another switch with more than 2 10Gb ports.
And of course make sure you have quality cables (at least Cat 6).
transfer initiated in windows explorer
I do have a 10Gb nic for my pc
Then try swapping the Synology port with the PC port, and measure performance between the PC and the QNAP. You can then swap again, and measure performance between the PC and the Synology.
That will give you a good idea on the overall performance gain you'd get, and also test the cabling.

I remote mounted a folder and im getting better speeds up to 292 MB/s

Transfer initialized from the PC, copying NAS1 -> PC -> NAS2, e.g. on a Windows PC in File Explorer?
However: Not what you are looking for right now, the obvious performance limitation with up to 110 MB/s is the PC network connection, likely operating at Gigabit Ethernet performance, limiting the speed here.
Difficult to answer the question where the GbE performance is lost, possibly unlucky (or no?) flow control settings on either or both NAS.

These are 10 Gb/s [bit] NIC, not 10 GB/s [Byte] NICs.
Much higher throughput could be achieved moving data direct from NAS to NAS view the pure 10 GbE data path. Both QNAP and Synology NAS have powerful Web UIs on board, allowing to direct "mount" one NAS on the other, and move the data through the 10 Gb connection.
An alternate approach could be connecting the PC using a 10GbE on a 10GbE port - of course, this requires some investment in a more powerful switch (more than two 10GbE ports) and a 10GbE network adapter for the PC.
Depending on each NAS storage performance, you could reach much higher data rates then these 110 MB/s - which is about the maximum possible on or over a Gigabit Ethernet network.
Happy New Year!

yes, transfer initiated in windows explorer. No items associated under traffic control so no flow control. I do have a 10Gb nic for my pc(asus rog) but i need to buy another switch with more than 2 10Gb ports.

pdasterly: Your results do sound like you are making all these transfers through a PC connected with gigabit ethernet.
If you want to measure the NAS<->NAS performance, you need to copy directly from one NAS to the other. That could be done via the web ui, or you could also use ssh.
Another path is to install iperf on both NAS, and do a network test between them that does not involve data transfer.
