Popular Post One and a half Posted November 12, 2018 Popular Post Share Posted November 12, 2018 Usually, I leave the settings alone for the Network Adaptors in Windows, but kludge and 'slow' copying speeds between machines across the network caused me to have a look at this again. In some cases Roon was starting to fluff and stall on DSD256 files, the machines themselves are quite capable of processing, so perhaps the NICs weren't tuned properly. In looking at the advanced settings, there are many settings to change but which one or more combo works to an optimum? A little searching, and I followed this page's advice and the stuttering disappeared, copying was a lot faster, and I noted the other day, using a really old SACD_EXTRACT files when ripping SACDs, copying rates were 2MB/s were possible, before they were about the 1MB/s. Here's a section when followed worked (for me) comments welcome. 4. Ethernet Adapter Performance Settings There are a variety of settings which may be available for your PC's network adapter that can improve throughput performance. These settings are associated with the network adapter hardware Open Device Manager. Double-click Network adapters. Right-click the network adapter you want, and then click Properties. On the Advanced tab, Look for energy-saving options and make the appropriate changes you want. Below is a description of these options and what they do. Maximize all adapter buffers and descriptors - Set these values as high as possible for maximum performance. On PCs with limited physical memory, this may have a negative impact as send buffers consume system memory. On most systems, however, the maximum setting can be applied without significantly reducing available memory. Receive Buffers: The buffer size of system memory that can be used by the adapter for received packets, which can be increased to help improve the performance of outgoing network traffic, but it consumes system memory. Transmit Buffers: The buffer size of system memory that can be used by the adapter for sending packets, which can be increased to help improve the performance of outgoing network traffic, but it consumes system memory. Receive Descriptors: Sets the number of Receive Descriptors that are allocated in the host memory and used to store the received packets. This can be increased if performance of received traffic is lacking. Transmit Descriptors: Sets the number of Transmit Descriptors that enable the adapter to track transmit packets in the system memory. This can be increased if performance of transmission traffic is lacking. Settings and Parameters to Disable Turn all "offload" options OFF - In almost all cases performance is improved only marginally when enabling network interface offload features on a PC. Offloading tasks from the CPU to the network adapter can help lower CPU usage on the PC at the expense of adapter throughput performance. Disable Interrupt Moderation / Set Interrupt Moderation Rate to OFF - This feature groups packets together and sends them as a batch. It can be responsible for sluggish tuning of the radio. Disable Flow Control - It sounds counter-intuitive to disable flow control, but TCP has it's own flow control mechanism and if an occasional UDP packet gets dropped, it has no appreciable impact on the performance of the radio. If your network adapter has the following adapter settings, set them as follows: Disable Receive Side Scaling Disable Adaptive Inter-Frame Spacing Set Enable PME to DISABLED Disable Packet Priority & VLAN Disable Jumbo Packet Granted there are other methods depending on what else is on the network, but are there any other guidelines audio enthusiasts can follow without stuffing up anything? i don't have managed switches just plain types.
