I noticed webservice performance downgraded after certificate got expired. However webservice-client app developed in a way to ignore possible certificate problems.

Is that possible that bad certificate can cause webservice-client app performance downgraded ? Can somebody point me on MSDN article confirming that ?

Update : I'm more interested from webservice-client app performance point of view.

For example: if client app (with patch to skip certificate errors) consuming web-service, will it work slower if certificate is expired ?

I suspected there will be some milliseconds on re-handshake or anything like that on every request if certificate is wrong.

    The performance of your webservice has nothing to do with your certificate being intrusted/expired or whatever status you mean by "bad" – Ramhound Feb 13 '17 at 20:34

In technical manner it may not downgrade webservice performance but it can in general manner. Certificate expiry or non-trusted certificate will cause warning message in the browsers which can lead normal visitor to leave the website with the assumption of dead/sick website.

We can't assume that all visitors coming to the site, will have technically background to understand and proceed on the website.
