Just starting with NetBoot and curious about what average times are. When I start NetBoot it takes about 25 minutes over 100Mb ethernet to get to Casper Imaging. My NetBoot.dmg file is 9GB (unsure if that is normal). Does this seem right? That seems like a long time to boot up.
Also, when I'm looking at server i never see any connections under NetInstall. Just says "No clients connected". Shouldn't there be something listed the moment a system starts to boot? I get BSDP Inform, BSDP ACK[LIST], and BSDP ACK [SELECT] shown in the logs.
Thanks

Which OS is the NetBoot hosted on?
Also, option boot the Mac. Select the NetBoot volume & immediately hold the CMD+V keys.
It should then verbose boot, & you can have some more feedback as to what it happening.

It's 10.9.2 with all updates applied. I did the option boot and have a fairly large log file. Only the first part will post. I'm not sure specifically what to look for in here.

IME, 9 GB is an average .nbi size. The netboot process does not send all of that over the wire though - only the tftp components the Mac requires to netboot. The rest is on the server.
I remember my boot times being somewhere around 20 minutes over a 100Mbps connection. It does matter what OS the nbi is being hosted from. .nbis hosted on a 10.6 server seem to perform much better than the same .nbis hosted on a 10.8 server.
Does you .nbi have a RAM disk? IME that kills performance, drastically increasing boot times.

How can I check if it has a RAM disk?

I'm having issues with netboot as well.
How can I get the log file from the last CMD+V boot session? It flies past really quick and I'd like to be able to read it all carefully.
