Hello! 

I'm using an academic free version on my server and I found that optimization time was equal to 2 minutes in the log, but real time was equal to 10 minutes. Could you explain this, please?

Thanks in advance

  Hi Andrey,

  It is possible that the machine was working at its maximum capacity and/or memory. Can you reproduce this issue? If you can reproduce this issue with a particular model, could you please share the model file? In this case please have a look at the Posting to the Community Forum article when sharing files in the Community.

  Best regards,
  Jaromił

  Thank you!

  The CPU usage was around 100% during the execution of the program. Does it mean that I need a more powerful machine?

   

  Best regards,

  It is good that the CPU usage is around 100% during program execution. This means that all CPUs are working to its fullest. A more powerful machine would not decrease the CPU usage but it would very likely improve performance. You can find more information in the KB article How does Gurobi perform on different computer hardware?
