My problem is a huge delay between the command and when I can actually see the ethernet data on the network (seconds..). WebAug 27, 2024 · The data rate for each connection is about 50Mbps. The client first push the data to a queue then another thread sends the data to server. If the data rate increases a bit, for example, it arrives 62Mbps or 75Mbps, the queue of the client becomes full and the client has to drop some packets.

Stack Overflow - Benefit of small TCP receive window?

WebMay 18, 2024 · This feature can negotiate a defined receive window size for every TCP communication during the TCP Handshake. In earlier versions of Windows, the Windows network stack used a fixed-size receive window (65,535 bytes) that limited the overall potential throughput for connections. WebFeb 23, 2024 · The TCP window size field controls the flow of data and is limited to 2 bytes, or a window size of 65,535 bytes. Since the size field can't be expanded, a scaling factor is used. TCP window scale is an option used to increase the maximum window size from 65,535 bytes to 1 Gigabyte. greenwich ct real estate scott elwell

WebNov 6, 2024 · If the underlying storage is small files, any file transfer protocol will have a problem with many of them. When IOPS of the array are the bottleneck, the protocol of the file server on top of it doesn't really help. Fastest would be copying one big archive or disk image. Mostly sequential IO, least file system metadata. WeblwIP is an implementation of the TCP/IP protocol stack. The focus of the lwIP stack is to reduce memory usage and code size, making lwIP suitable for use in small clients with very limited resources such as embedded systems. In order to reduce processing and memory demands, lwIP uses a tailor made API that does not require any data copying.
