Performance profile
How much work a call to WP_Network_Query::parse_query() does, and what it touches: the algorithmic scaling, the Zend instruction count per call across PHP versions, the hooks it hands control to, and the core code that calls it. Measured from the compiled opcodes, not a stopwatch, so every number is identical on any machine running the same PHP version, and every function in core is ranked by cost.

Touches nothing outside its own arguments.
No loop in the body: the same number of instructions runs whatever you pass in.
Executed per call on PHP 8.5, depending on the branch taken. The body compiles to 20.
Third-party callbacks on 'parse_network_query' run inside this call, and their cost is not bounded by anything here.
1 place in core call this, so the cost is paid more often than your own code shows.

What one call costs · 1 distinct outcome
One number would be a lie: the work depends on which branch runs. These are every distinct cost WP_Network_Query::parse_query() can have, taken from its control-flow graph on PHP 8.5.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 18–20 | wp_parse_args() |
Across PHP versions
Compiles the same on PHP 7.4, 8.1, 8.2, 8.3, 8.4, 8.5 and 8.6-dev: 20 instructions, 18–20 executed per call, 1 branch. The work does not change between versions.
An instruction is not a fixed amount of time, so a matching count is not necessarily the same speed; what it rules out is a difference in the work itself.
Hooks and filters fired · 1
One hook fires while WP_Network_Query::parse_query() runs, in this order:
- do_action( parse_network_query )actionline 164 (+14 into the body)
Fires after the network query vars have been parsed.
Uses · 2
- wp_parse_args()Merges user defined arguments into defaults array.
- do_action_ref_array()Calls the callback functions that have been added to an action hook, specifying arguments in an array.
Used by · 1
- WP_Network_Query::get_networks()Gets a list of networks matching the query vars.
