slow module loads and purge

[puneet336]

Hi ,
We are currently in a situation where in we installed a R bundle using easybuild. but with the generated module files, the module load and module purge are taking more than 15 seconds.
I f this was a code, I would have attached a debugger to see which line of code is taking longer. Could you please help me to understand how and thich tools can I debug the root cause of slowness here ?
Here is the command I use to reproduce the slowness -

So far we have observed slowness issues with only this particular module.

Example:
[singhpuv@server ~]$ time module load R-bundle-Novartis

real 0m16.866s
user 0m15.105s
sys 0m0.082s
[singhpuv@Pserver~]$ module list
