How to increase the speed of a gigibit network?

Question

Iron

The network is gigabit. But data is transferred at a rate of 55 MB per second. In what there can be a reason (speed of disks is enough)?

Answer 1

eemm, with such introductory - in everything. There are so many of them, that the fingers of the hands are not enough to list. Let's get more info. Very much more.

Answer 2

A well-formulated question contains half the answer.
Check the network separately, the disk subsystem separately.
Run a network test on two hosts using, for example, iperf . Get clean, uncluttered data with data overhead and eliminate data access speed.
I am quite sure that your problem is not in the network, but directly in the way data is transmitted. You didn't say a word about the data transfer method. Probably it's about some kind of abstract file storage... Then you also need to know what it is made on and what OCs are used for the client/server.

Answer 3

55 megabytes per second (440 megabits per second) is a perfectly normal file transfer rate over a local gigabit network. Ethernet is an asynchronous network, the upper limit in it is, in principle, unattainable, it is theoretical. In addition to the actual data, headers of different levels are transmitted, broadcast requests are transmitted, collisions occur depending on the total network load, and the application layer protocol can introduce its own delays. You can try to slightly increase the speed within a few percent by
- Increasing the MTU (if the channel equipment supports Jumbo Frames)
- Increasing the TCP window size
- Network segmentation, in order to reduce the number of broadcast requests.
- Switching to another application file transfer protocol

Answer 4

just in case, I'll ask: is a gigabit switch used or are the computers connected by wire directly?
