Re: [sumo-user] Can not figure out timing for different traci function

Hello,

the delay most likely comes from loading the network and setting up all the necessary simulation objects in memory.

If you need to start a simulation repeatedly, you can avoid the overhead of network loading by calling traci.simulation.saveState and traci.simulation.loadState

Hi all,

I have two codes below. In traci_demo_v1, I have a loop that just starts and closes a simulation and prints the time taken to do so. In windows, it takes around 0.5 secs but when I check my task manager (Memory Usage.PNG file attached below) I see only some memory use of 35MB and no disk usage. So I was wondering why it takes so long to start or load a state (without gui)? Is there any way to reduce this time? Also, in traci_demo_v2 I have a simulation that runs for sometime with step-length 0.5. But when I measure the time across traci.simulation.getDeltaT(), it takes from 0 to 0.001 seconds rather than 0.5 seconds. So, I am a bit confused about how long it actually takes for sumo to perform one simulation step?

I am using SUMO v1.7.
