Bug #: 52537
Summary: slow trim function
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: libfortran
AssignedTo: [email protected]

Hello,
The trim function in Gfortran seems to be a a lot slower than the intel
compiler. Sometimes I have to read some input text files which can very
large(1.5GB); Comparing the intel and gfortran, the gfortran takes 150 seconds
where intel spends only 50 seconds. I checked, and there seems to a large time
spend on the trim function.
I am not sure if intel does some other optimization but I never got such huge
performance difference between gfortran and ifort.
Thank you.
