[satosa-users] SaToSa throughput problems

Hello SaToSa list! We are experiencing unexpected poor performance with SaToSa. (1K requests/minute) . We are seeing very high resource use with XMLSEC binary (default option) and using pyXMLSecurity (crypto_backend configuration) with encryption disabled. Here is our setup: Load Balancer=>EC2=>NGINX=>Gunicorn. (NGINX=>Gunicorn is on the UDS, not network stack) EC2 instance size information: (OS is AWS linux) Model vCPU Memory (GiB) Instance Storage (GiB) Network Bandwidth (Gbps) EBS Bandwidth (Mbps) c5n.2xlarge 8 21 EBS-Only Up to 25 Up to 4,750 Gunicorn is set to the "thread" model: import multiprocessing workers = multiprocessing.cpu_count() * 2 + 1 threads = multiprocessing.cpu_count() * 2 + 1 We have 8 core boxes. Any suggestion on things we may try ? TIA -Jonathan
