You should probably have a look at modperl. (http://perl.apache.org/) There's also a book available for free: http://modperlbook.org/ Modperl will compile your perl scripts only once, and answer all requests with the already compiled scripts. Update: To go more into the details: It's hard to say what needs 3 seconds, without having more data/the code. I could think of: Perl needs some time to compile the packages Perl needs so long in order to find the package The database connection is established while requiring the packages, this could also take 3 seconds However, all of the points above could be solved with modperl, the database connection could also easily be made persistent.(Apache::DBI)	[reply]

While I think that "misc" has the right answer, if you don't want to use mod_perl, you could have your friend update the module so that the connection to the database isn't created until the connection needs to be used. Basically a lazy connection to the database.	[reply]

Do you have any idea what the problem might be? Not unless you include your code. Read How do I post a question effectively? and update your node with relevant information. -- Andreas	[reply]

Thank you Andreas. I don't believe that a 56Kb file, which means about 2000 lines of code would help you. As for the script where I try to include the package, it is a simple use Libs::MyPackage; print "package included";	[reply]
Re^3: including a package - time issue by Corion (Patriarch) on Aug 27, 2007 at 10:45 UTC
The code you posted does not neccessarily indicate that `Libs::MyPackage` is the problem. Look for example at this code: `use Libs::MyPackage; print "Package included\n"; BEGIN { sleep 10; };` [download] This will print "Package included" only after 10 seconds. Any <c>use line is equivalent to a BEGIN block, so any other module could cause the same problem, as could any not/slow responding network drive if you're (trying to) loading modules from there. Also, a virus scanner might run wild.	[reply] [d/l] [select]

Serious question: Why don't ask your friend? Since he wrote the package, he's going to to have a greater insight into why it might be taking longer than you think it should.	[reply] [d/l] [select]
