[Chimera-users] delay in starting the program

Hi Eaazhisai,

  When Mac X11 Chimera starts it uses osascript to start the Apple X11 
server if it is not already running.  First it tries to determine if X11 
is already running.  That can take a bit of time since it simply tries 
to connect to X11 and has to wait until that connection fails.  All of 
this start-up can take a bit of time -- on my 2 year old MacBook Pro 
laptop running Mac OS 10.5.6 it takes 15 seconds.  The second time I 
start it takes only 2 seconds because X11 is already running and Chimera 
is already in the operating system in-memory disk cache.  If you want a 
little faster start-up the first time you can use Mac Aqua Chimera -- 
took 8 seconds the first time, 2 seconds the second time on my machine.  
I recommend the Mac Aqua Chimera instead of the Mac X11 Chimera because 
Apple does not support X11 well.
