Database Connection Benchmark

What it the minimal time to get any result from a database?

We open a connection, perform a trivial query (current_timestamp is probably fine) and disconnect.

There are (at least) three times we are interested in:

  • The time from initiating the connection to the end.
  • Same plus the time to load any necessary libraries
  • Same plus the overhead of starting the script

The first is the one important for long-running servers which for some reason don't want to keep a persistent connection to the database.

The last is for command line tools, CGI scripts, etc.

The second doesn't have that much practical importance. That's just personal curiosity.
