#565 closed defect (worksforme)

network/nfs performance too low

Description

I usually get about 95 MBit on my 100 MBit LAN connection. When compressing a
raw YV12 file from NFS to a local driver, the network traffic is at 35-37 Mbit
only and the CPU consumption is at approx. 28%. Rerunning (reading from cache)
improves framerate from 5 to 16 fps (for the first few). I guess mplayer does
not use a separate thread to pre-buffer input data. Maybe it should. Or is there
a work-around in terms of NFS mount parameters?

ahem, "driver" -> "disk"

-cache makes MPlayer use a separate _process_ to pre-buffer input data. Have you
tried that?

  • Resolution set to worksforme
  • Status changed from new to closed

-cache should work well enough -> closing
