WPSSO Core and it’s add-ons are extremely fast – usually running in less than a millisecond. For example, here is the load time on the wpsso.com home page:
<!-- added on 2018-10-16T18:15:51+00:00 in 0.000866 secs from https://wpsso.com -->
Which includes several add-ons:
<!-- generator:1 --><meta name="generator" content="WPSSO Core 4.16.2-dev.1/L"/>
<!-- generator:2 --><meta name="generator" content="WPSSO BC 1.6.0/F"/>
<!-- generator:3 --><meta name="generator" content="WPSSO IPM 1.2.0/F"/>
<!-- generator:4 --><meta name="generator" content="WPSSO JSON 1.34.0/L"/>
<!-- generator:5 --><meta name="generator" content="WPSSO ORG 1.4.2/L"/>
<!-- generator:6 --><meta name="generator" content="WPSSO RRSSB 1.10.2/L"/>
<!-- generator:7 --><meta name="generator" content="WPSSO TAQ 1.4.1/F"/>
<!-- generator:8 --><meta name="generator" content="WPSSO TIE 1.2.0/L"/>
<!-- generator:9 --><meta name="generator" content="WPSSO UM 1.13.0/F"/>
Have you posted your issue to the support forum? It sounds like there’s definitely a problem if WPSSO is affecting your page load time.
