Slow ethernet in linux

Still It is unclear to me why wget from Internet is pretty slow at ~4-6MB/s, and maks 10MB/s at the start of download.


in a nutshell, wget is single-threaded, has a bit of overhead, and highly dependant upon the server.

netperf is designed to have low-overhead on both the client and server, as well as being multithreaded.


but there are a lot of other factors involved as well, such that there is usually never one single smoking gun. 

That's why I use queuing and fully multithreaded network test apps for benchmarking, and don't worry about what wget or curl tell me. 

That said, i haven't noticed a significant drop in network speed on the pine while downloading locally with simultaneous interactive ssh sessions with queuing enabled - as it should be.
