PageSigner v3 implements the TLSNotary protocol compatible with TLS 1.2+. Additionally, not only the server response gets notarized but the request as well.
This new version takes more time to complete than how it was before. Whereas earlier the notarization would usually complete within 10 sec, now the expected wait time is from 30 to 90 sec. Your internet connection speed will be the decisive factor as anywhere from 50 to 100 MB of data needs to be exchanged as part of the TLSNotary protocol.
