I repeated all of them at least twice, to see if I got the same result.
And indeed the very first run (PyScripter) was about 150 sec.
So I think the above mentioned values give a good impression, nothing more.

well my windows version doesn't understand that :
Searches for a text string in a file or files.
FIND [/V] [/C] [/N] [/I] [/OFF[LINE]] "string" [[drive:][path]filename[
/V Displays all lines NOT containing the specified string.
/C Displays only the count of lines containing the string.
/N Displays line numbers with the displayed lines.
/I Ignores the case of characters when searching for the string.
/OFF[LINE] Do not skip files with offline attribute set.
"string" Specifies the text string to find.
Specifies a file or files to search.
If a path is not specified, FIND searches the text typed at the prompt
or piped from another command.
