Running some services is too slow

Notes

This issue might be related with how we currently handle some things inside the services themselves. I will describe the scenario first.

Manifesting this issue is the sleeper service. All computational services should have the same issue as well. The dynamic services might inherit the same problem.

What actually happens

I was able to observe this happening only on master.

How to reproduce:

• create a new study
• add the service sleeper not the gpu or mpi version of it
• press run button and look at the service logs

It will try to change permissions to around 5000 files in the input folder and 300 files in the output folder. These operations take a lot of time.

If you start a new terminal in the running service you can see there are a lot of directories inside the input folder.

@pcrespov @sanderegg you might have more insight on why this is happening
