Excesive requests to remote license server

Hello,

In our work group we have a little problem. We have a remote license server, so several people can use Quartus from different machines by calling this server. The problem is that Quartus launch a lot of license requests everytime we make a task of the compilation (Analysis & Synthesis, Fitter, Assembler, Timin Analisys and EDA Netlist Writer). So, the final result is that a simple compilation lasts about 2-3 minutes.

Is there any chance to reduce this inefficiente times? We have a good connectivity, it doesn't seem to be a network problem.
