Latest seems to be working better on the device so...

Now with the "single init" feature enabled, the first run includes
setting up (init), where as subsequent runs do not need to init.

search-name runtime was 4.2 seconds
search-name runtime was 1.7 seconds
search-name runtime was 1.9 seconds
search-name runtime was 2.6 seconds
search-name runtime was 0.3 seconds
search-name runtime was 2.0 seconds

get-depends runtime was 4.1 seconds
get-depends runtime was 0.3 seconds
get-depends runtime was 0.4 seconds
get-depends runtime was 0.4 seconds
get-depends runtime was 0.4 seconds

get-description runtime was 3.9 seconds
get-description runtime was 0.2 seconds
get-description runtime was 0.1 seconds
get-description runtime was 0.1 seconds
get-description runtime was 0.1 seconds
get-description runtime was 0.2 seconds


Interestingly, if I run search-name inside the time command, I get
consistently lower results, with subsequent calls after init taking less
than 0.4 seconds to complete. Does anyone have any thoughts on why this
might be the case?

Regards,

Thomas
