Honored ContributorYour design can run considerably faster on Questa as there are no RTL or gate-level optimizations in ModelSim.
You will also save time in either version of ModelSim or Questa, interactive or batch, by waiting to turn on signal logging until after 2ms have passed. The way to get batch mode from waveform stimulus is to export the wave data into a Verilog or VHDL testbench so you can load it in as your top-level design unit. Then you can run your simulation in batch and use the checkpoint/restore commands to save simulation cycles. This is all described in the ModelSim/Questa user guide.
