http://ubuntuforums.org – Hi all, This is my first post to these forums. I've been playing with Ubuntu for a while now and have used these forums to help me out with many problems, unfortunately I cant seem to fix my current problem. I've setup a box (HP Proliant Microserver N36L) running Ubuntu Server 64bit 12.04.1 LTS to act mainly as NAS and I'm experiencing extremely slow network speeds. I know the various file sharing protocols will be slower than raw speed but my problem seems to stem from the raw speed. Firstly my hardware: HP N36L has onboard gigabit lan. Using cat 6 cable connected to 10/100Mb capa (Hardware)
