0	218	Office network.SALES	Config.	Application	Setup	SYMPTOM(S): <NL>  Some application sessions may <NL>  not have been started in this <NL>  network <NL>  (this message will not be repeated) <NL>  <NL>  The initial application session was <NL>  not started for Ftp <NL>  on this client <NL>  <NL> CAUSE(S): <NL>  The initial start time was calculated <NL>  as 4636.199575 for Ftp <NL>  on this node. It is after the end of <NL>  simulation duration, which is set to <NL>  3600.000000 secs. <NL>  <NL> SUGGESTIONS: <NL>  1) This may be the expected behavior <NL>     for this client application, based <NL>     on the Client Start Time, and the  <NL>     specified session inter-arrival rate <NL>     and distribution <NL>  2) Increase the Simulation Duration <NL>  3) Increase the application session <NL>     rate for applications in this <NL>     network <NL> 
3600	54918	Office network.SERVICES	Config.	Event Manager	Performance	Try setting the 'event_speed_parameter' to (3640). <NL> This is a preference under the category called 'all'. <NL>  <NL> The advanced event management system in the Simulation <NL> Kernel can be tuned to maintain peak performance when <NL> simulating very large systems. Your trade-off is that <NL> higher values of event_speed_parameter require <NL> additional memory. <NL>  <NL> Optimal values depend on the type and size of models, <NL> so the value above is an estimate based on how this <NL> simulation performed. You may wish to experiment <NL> with different values and compare the simulation's <NL> performance. In general, increasing this parameter <NL> will not yield significant performance gains for small, <NL> lightly-loaded systems. <NL>
