What is the difference between tls and ssl?

I don't have any experience. I want to share my experience with some experienced developers. for developers, using tls and ssl is just a different configuration? Does openssl implement both protocols? When using tls or ssl, is it true that https is used during access? Because I have no experience in use, the following are a few questions. I hope experienced students can share their experience with me:

• For developers, using tls and ssl is just a different configuration? Does openssl implement both protocols?
• When using tls or ssl, is it all called through https?
• What is the time difference between using and not using https?
• If the configuration is performed on the proxy server and N tomcat servers are attached to it, will the bottleneck occur on the proxy server? What if I configure them on tomcat?

TLSYesSSLNew name,SSLFrom 1.0 to 3.0,TLS 1.0=SLB 3.1.
OpenSSL implements SSL1.0 ~ 3.0 and TLS1.0 protocols.
HTTP over SSL/TLS is HTTPS
Unless it is a large file download website, the performance of HTTP and HTTPS is not much different.
Generally, Tomcat is very slow. If the proxy server uses Nginx or Apache, the bottleneck will not appear on the proxy server when 1 is dragged to 10, but it is hard to say more.
