Ooooh! Interesting!

 I have an app I haven’t touched for a while that makes heavy use of filter of string variables up to 1,000,000 lines (but often only hundreds to tens of thousands of lines).  In my case finding all lines containing the to be found string  is a benefit

I have long intended to see if I can speed things up a bit.  Should I go back and look at converting string lists to arrays, then using filter, and finally converting back to a variable?  I suppose I could do this contingent upon number of lines just in case time penalties and benefits are not linear…  

Any thoughts/advice welcome.

Cheers
