Hi All, The computers connected to my slowest switch always boot almost a minute earlier than those connected to my faster switch! And furthermore, the slower switch has to go through the faster switch to get to the server.
I've got a teacher-computer serving, via ltsp-pnp, a classroom network with 30 fat clients. This server is connected to a Netgear 24 port switch (model FSM 726) through 1 of its 2 gig ports: the rest of the ports are 100 MB. The other gig port on the Netgear switch is connected to a Cisco 24 port switch (only has 100 MB ports) on the other side of the room. Look if you will at the Epoptes benchmark tool results (*http://tinyurl.com/p6ewzxa <http://tinyurl.com/p6ewzxa>*) the faster-booting computers that boot off the older Cisco switch average around 25 Mbps (7A-8B), this makes sense since they share a single 100 mb path to the server. The slower-booting computers that boot off the faster Netgear switch average around 70 Mbps. these numbers all makes sense. So, why do those last 4 computers, the ones averaging around 25 MB/s each, boot long before the other 12 computers, even though those 12 computers are directly connected to the first gig switch and are getting faster service (apparently)? This doesn't seem a flow control issue since the benchmark clearly shows the slow-booting computers have faster communications. Clue? the slow-booting computers take a loooong time to get an address from DHCP. Any ideas? Thanks, David
