There is a pause every few seconds when I am writing to the server. This causes the video that I am recording to have jerks and lost frames. The tcp stream is not constant. I will try to explain the best I can. I have a server for video use. I connect the videoserver with Macs using cross cable. Using NFS version 3 and using tcp. The filesystem on the server is XFS. On the macs there is a dv camera connected. Using a video editing software, I am recording the video to the nfs mount on the mac. After the recording when I play back the recording there are jerks in the video every 20 seconds or so. Next I copy a big file to the nfs mount. The file goes through but I notice that there is pause every 20 seconds or so. DV video only need about 3.5MB per second. All the ethernet connection is gigabit. What am I doing wrong? Please do advice. P.V.Anthony -- gentoo-amd64@gentoo.org mailing list
