Sylvia Gise 7 Performance impact since TLS 1.0 shut off
Comparison between our production org and a test org seems to be indicating that network traffic, the callouts to internal services are about 3 x longer. In fact, almost all “traffic” from Salesforce to the browser is also 3 x longer.
The timing seems to align with Salesforce upgrade of TLS in all sandbox org’s which was done over the weekend of June 25. One thought was our 2 way SSL. Do we need to reimport a higher level of certificate into our org’s? Cannot find anything related to what we are seeing, i.e. no suggestions or best practices, etc... have been found on the discussion forums or other searches.

Sylvia Gise 7It was determined around the same time this TLS change was done, our security admin also made a change to our WebSEAL (reverse proxy). The WebSEAL was actually moved to a different environment which was much more heavily used. This was causing the performance issues. Renegotiation was being performed due to the TLS change but this was determined to not be a cause of the performance issue. Once the WebSEAL was moved back to the original environment, the issue subsided.
