Hello monks,

a collegue of mine stumbled upon something curious: in his script (let's call it main.pl) he has 56 subs he needs.

In scenario 1 he put each sub in a different file, each appropriately named getSynthesedata.pl, transformOrdToCSV.pl.

He then loads all the files using 56 different "do" statements: 

do 'getSynthesedata.pl';
#times 56 for each other file

[download]

In Scenario 2, he catted all those files (and nothing more) to one script called all.pl, and only loaded that file: 

do 'all.pl';

[download]

Now, loading the 56 different files takes less than one second, loading all.pl takes about 5 seconds. We can't really explain it.

Maybe it has to do with multicore?

Does 'do'-ing a small file has certain benefits?

In reply to Loading one big file is slower than loading 56 different small files? by wdsaeghe
