For a video player I am using totem. I have three "console" servers that sit in separate server rooms that are all running CentOS 5.7 64bit latest at the moment (will be upgraded to CentOS 5.8 over the weekend). The OS is running bare metal on the server and everything is local. The specifications of the servers are 1. Dell PowerEdge 1950. CPU Xeon X5260 @3.33GHz, 16GB of RAM, disk RAID1 of 250GB 7200rpm SATA 2. IBM x336. CPU dual Xeon @3GHz with 2MB cache, 8GB of RAM, disk RAID1 of 147GB 10krpm SCSI. 3. Sun Fire V20z. CPU dual Opteron 244 @1.8GHz 1MB cache, 8GB of RAM, disk RAID1 of 147GB 10krpm SCSI All three servers have dual 1GbE ethernet connections in an active backup configuration (that should be changed to balance-alb which is our standard config). The network switches in the middle are a mix of Cisco 6500 to which the console servers are attached, which are in turn connected to Cisco 4500 to which all the desktop machines are connected. My understanding is that the switch interlinks are 10Gb apart from the Sun Fire V20z which is currently has four 1GbE connections to the core (it is changing to 10Gbps soon to support a IBM Power p720 for TSM backup). All three servers are using xrdp-0.5.0-0.6.20090811cvs.el5 RPMS from the EPEL repository with a x11rdp that I compiled myself. My test client is a stripped down PC, it has a Core2 6400 @2.13GHz for the CPU, 2GB of RAM and a single 500GB 7200rpm SATA disk that it boots from. The video card is a nVidia GeForce 7600GS and has a 24" LCD at 1920x1200 and a 20" LCD at 1600x1200 attached. It is running CentOS 6 latest in 32bit mode, with onboard Intel GbE running at 1Gb. I am using the rdesktop as the client version 1.6 (latest in CentOS 6). I also have FreeRDP but I only use that for connecting to Windows 2008 terminal servers (rdesktop 1.6 has cursor/pointer issues). Basically running the Big Bugs Bunny video in a window at 1:1 works fine on all the servers if they are not doing anything else. The CPU is maxed out between totem, xrdp and x11rdp on the IBM and Sun. The Dell has some headroom for other stuff. Only the Dell can manage running a 2:1 without dropping any frames, and then I need to kill anything that is consuming CPU (aka Firefox). Historically when my client was on a 100Mbps connection, a 480p video would drop frames. Not so as to make the video unwatchable, but definitely noticeable. I don't run sound on any of this as it sound is an issue is a shared office. Clearly using MS-RDPEV extension would reduce the server and bandwidth requirements, but would hike the client CPU requirements. JAB. -- Jonathan A.
