in thread How to improve speed of reading big files

I used the above code with some minor modifications : i remove the day at the beginning of each line to have the time in front -> ready to be sorted and no substr needed!

results are:

- before (old old old code, no tweaks) --> 84sec
- new and improved code --> 17 sec

The biggest gain (more than 40 sec) was on using the while on the handle instead of the list context with grep

Thanks a lot !!!

Chopping off the date instead of prepending/sorting/removing the time--cool! Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
