Slow System Info

This code runs sometimes in less than one second, but sometimes its very slow???

(system info)

Would this be quicker as a shell command?

do shell script "system_profiler"

This may take a while to run but will return everything you may need to know about your system.

You could also try

system_profiler SPHardwareDataType
system_profiler SPNetworkDataType
etc…, as a do shell script to narrow your results (and make it quicker!!)
