Quite boring, really. Have faffed about with computers since the mid-80s, have worked as a network engineer, unix sysadmin and (occasionally) developer.

comment Need reasonably priced router with QoS support
Unless you're doing connection-tracking (like, say, NAT), the number of simultaneous TCP connections is pretty much a non-issue. What aggregate bandwidth are you expecting?

comment What are your best senior level Linux interview questions
It at least used to be the case that editing config files in AIX did not result in daemons changing behaviour, as they picked up the config from a binary database, instead of the plain-text config file.

@Martin: In that case, I suspect Fluke have one or more suitable devices in the USD 1000+ cost range

comment Basic multicast network performance problems
Might be. Might be worth testing, to see if it is that that's killing your CPU (probably out of hours, though). Can't say I've seen it in the 4900, but I have certainly seen packet-loss due to te presence of IGMP snooping on 4ESW ports.

comment Basic multicast network performance problems
Might be worth disabling IGMP snooping, I've seen issues due to that on other platforms (though that was packet loss rather than latency).
