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.
