First off, you really need to join a Perl and/or DBI users list, found at lists.perl.org.

DynaLoader is used to load modules at runtime. It's part of Perl, you don't need to be too concerned with it unless it's taking a lot of time.

Hi:

I am using this command to profile a perl program on our unix box

/tools/bin/perl -d:DProf my_program.pl.

and then "dprofpp -u" to get the following:

Total Elapsed Time = 0.477847 Seconds

User Time = 0.319582 Seconds

What is "DynaLoader::dl_load_file" corresponding to in my perl code? TIA.
