I use a resolution slightly less than 1280x1024@16bpp in order to have it fit maximized on the workstation I'm using. If you have TightVNC installed, you might try enabling some of the compression and quality features and make sure that "tight" encoding is in use. You may be running into an issue where "raw" encoding is chosen which will be agonizingly slow (and probably not happening since you seem to be describing a bit more responsiveness than what would happen in "raw" mode). For starters, you might try 'vncviewer -encodings "tight copyrect" - -quality 6 -compresslevel 6 ...' > seems that 1024x768x16bit color was making a huge amount of constant > network traffic (over switched 100mbs ethernet), but 800x600x16bit is > much more reasonable. > > So do i ned to use fibre channel or gigabit ethernet to have 1024x768 > work reasonably? > > >>Server has 1 gig of SDRAM, never hits the swap >>Terminal has 256 megs of SDRAM >> >>NFS Swap is turned off >> >>terminal and server NIC and switch are all set for full duplex >> >> >>> >>>Jason A.
