Slow execution of fortron executable in Azure

Hi, 

I am facing a problem of slow execution of FORTRAN exe which we are calling internally from our azure deployment solution, in local machine I am getting result in 17-18 second, while at azure server it is taking around 35 seconds to get the result. Local machine is of 4 GB RAM while Azure VM is of 8 GB RAM.

Steps. -     In our published application we are doing following activities.

1.       Read data from SQL Azure Server& CSV files & display in on HTML5 pages.
2.       Write data on CSV files.
3.       Executing a external Fortron exe, which reads data from csv files generated in step 3.
4.       Fortron exe after calculations write data on .txt file.
5.       Read text file data generated in step 5 & display it on HTML5 pages.

Issue:

In point # 3, when we are invoking fortron exe using process start method, then –

                On local machines in usually take 17~18 secs

                On cloud server this is taking 34~35 secs.

Rest all other activities are taking same time on local as well as cloud server.
