Then use a diffie-hellman (DH) password, or use a different source, such as Performance_schema, slow query log, which depends on which one your application supports, or it may contain some load-balancing settings.

SSL latency may also get worse. If you need to obtain an existing certificate or execute Online Certificate Status check (OCSP), we will need a new TCP connection, it also increases the latency of hundreds to thousands of milliseconds.
How is it "fast enough "?
We can see that the server response time is only 20% of the total latency, and other operat

Introduction to OpenSSL
OpenSSL is a rich and self-contained open-source security toolbox. It provides the following main functions: SSL protocol implementation (including SSLv2, SSLv3 and tlsv1), a large number of soft algorithms (symmetric/asymmetric/abstract), big number calculation, asymmetric algorithm key generation, ASN.1 codec library, certificate request (pkcs10) encoding/decoding, digital certificate encoding/decoding, CRL encoding/decoding, OCSP

A request took 470 milliseconds, of which 80% of the time was taken up by network latency. See, we really have a lot of things to do! In fact, 470 milliseconds has been very optimistic:
If the server does not reach the congestion window of the initial TCP (congestion window), which is 4-15kb, more round-tripping delays are introduced.

Monitoring Tools
If you are using pcap-based tools such as VividCortex and pt-query-digest, you should ensure that these tools are still usable after SSL is deployed and can provide keys for implementation. Then use a non-Diffie-Hellman (DH) password, or use other sources, such as performance_schema and slow query log. it depends on which application supports the password, it may also contain some server load balancer settings.

OpenSSL is an open source SSL implementation. The simplest and most important application based on the OpenSSL directive is to use Req, CAs, and X509 to issue a certificate.OpenSSL provides command-line options and interactive two ways to perform various operations.Enter OpenSSL directly on the command line to enter the interactive shell, as follows:[[emailprotected] local]# opensslopenssl> helpopenssl:error: ' Help ' was an invalid command.
