This may not be a Fortran issue, but since transfering my C and Fortran projects over to Visual Studio 2010, I have found the the compilation/composing perfomance of the Intel Composer XE 2011 is very slow. The compilation of C code is fine.
Looking at the Windows Task Manager, I can see the the two cores are inactive for about 28 seconds out of 30!
The memory usage is constant, but the CPU remians at 0% for 90% of the time.
Could this be a licensing issue?

I should note though that our Fortran compiler will only use one core. It is not a parallel application, while you can specify parallle builds with the C compiler.

The C projects are using Microsoft C, so they are not using the same licening mechanism.
I tried copying the .lic files to the compiler bin\ia32 directory, but this made no difference.
Have you any other suggestions?

I also have a setting for LM_LICENSE_FILE, which chklic is checking. Is this likely to slow down the response?

When I run chklic, the LM_LICENSE_FILE network locations were certainly at the bottom of the list. The local INTEL_LICENSE_FILE license file was checked first.

"There has been no change in the licensing mechanism to check LM_LICENSE_FILE before or after INTEL_LICENSE_FILE locations. I believe that it is inherent in FlexNet Licensing to check ALL locations before returning (even if a valid license is found in the first location), so the mere fact of specifying many locations or keeping a large number of license files will slow down license checkouts. As far as I know, the only difference between chklic checkouts and Composer checkouts is that Composer has a few hard-coded locations.
If you want to see where Composer is looking for licenses, you can set the environment variable INTEL_LMD_DEBUG to 1 for console output or a log file name to capture extra information. Additional information is also available by setting FLEXLM_DIAGNOSTICS=3 for more verbose console output."
