Newton: Extremely slow horizon [closed]
Hello all,
I have a controller with 10GB RAM and 5 vCPUs. Horizon access is very very slow. It takes 2-3 minutes to load login page and after that 1-2 minutes to process a single request. I am not running any big setup. Hardly 2-3 testing instances so there isnt much load on any of the nodes.
Also I can see multiple nova-api processes in top command on controller. I googled and found that there is a way to control number of workers but that configuration isnt working in newton release for me. I tried to restrict ec2, osapi_compute and metadata workers to None, but this failed as None wasn't a correct value since nova-api process failed to restart. Please share if anyone has worked on this and got it working. I think this should help me solve my problem.
Please suggest if anyone has other ideas as well to troubleshoot this.
UPDATE #1: CONTROLLED Number of WORKERS:
In nova.conf, do this to restrict number of workers:
osapi_compute_workers=1
metadata_workers=1
