![]() The raw network speeds tested with iperf3 were between 5 and 10 Gigabits/s.(tested with dd and Blackmagic Speed Test) The disks used were all RAID 5 arrays with local speeds between 600 MB/s. With the default setting which enables signing, the speeds were even (a lot) worse: around 60-70 MB/s. The problem is really specific to SMB on Mac.Īll the machines have SMB signing disabled as per Apple's recommendation. The slow speed is when transferring files between two Macs or when the Mac is reading from a Win/Linux share. The transfer speeds between the Windows or Linux machines are OK: between 500 and 800 MB/s for big files (10 to 100 GB).īut the Macs show a read speed of around 130 MB/s only.Ĭuriously, write speeds when writing from Mac to Windows or Linux, are much better. This Sonnet solution is perfect for high-performance computing where low latency, high bandwidth, and low CPU overhead are required.We have a 10 Gigabit network with a mix of Windows 10, Linux and MacOS (Sierra 10.12.6) machines. Setup is simple-after installing the low-profile card into an available x8 or x16 PCIe slot in your computer, just download and install a driver, connect to the switch or device’s 10GbE port via LC optical cables (SFP+ optical transceivers and optical cables sold separately), CAT-6 or CAT-6A copper cables (RJ45 SFP+ copper transceivers and cables sold separately), or direct attach Twinax copper cables (sold separately), and then configure the card through the OS X® Network control panel or Windows Device Manager. The Presto 10GbE SFP+ dual-port 10 Gigabit Ethernet PCI Express 2.0 adapter card enables you to connect your computer to high-speed infrastructure and storage without stepping down in speed. Presto 10GbE SFP+: Provides 10GbE Connectivity to Mac and PCs Sonnet offers a powerfully simple way to add dual-port 10GbE connectivity to your Mac Pro® tower, Windows® PC, or Linux® server-the Presto™ 10GbE SFP+. With increasing demands for greater data transfer speeds and more bandwidth over shared networks, and with specialized applications such as HD video editing using high-performance shared storage systems, it’s no wonder that 10 Gigabit Ethernet (10GbE) use has skyrocketed-this high-speed cabled networking standard offers ten times the performance of Gigabit Ethernet, the common wired network connection included with most computers today.
