== CPU max ==
 * epics channels to store => DAQ flow
 * general epics channel => normal TCP/IP flow
 * RCG 3.1 improves the double traffic
 * Also slower than 3GHz CPU is not good
 * slot of PCIE card - one stop card matters
 * when we put a interface card of the raiser card to closer to mother board card was not good - LIGO: it shouldn't matter
 * Priority of riser cards may be necessary (not much related to the current cpu issue)
 * epics gateway (machine) may be necessary to collect the epics information and reduce the redundant traffic

== broadcaster ==
 * dedicated network from bcst low latency
 * not same swich from the control room client machiens'
 * 1Gb switch is fine
 * not all chans are sent to dmt

== svn ==
 * svn web interface changed
 * freeze the svn at RCG 3.5 for O3 and move to git
 * svn version is updated - Keith will send the info
