Performance profile
How much work a call to wpmu_log_new_registrations() 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.

Reaches the database via get_user_by().
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 44.
Nothing here hands control to plugin code.
Nothing in core calls this; the cost is only what you spend yourself.
What it touches
- querycontent query
get_user_by()one call below wpmu_log_new_registrations() - optionoption read or write
get_option()one call below wpmu_log_new_registrations()
Further down the call graph this can also reach hook, cache, serialize and transient. Those are the worst case, several calls deep and usually down an error path, not what a normal call pays.
What one call costs · 2 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost wpmu_log_new_registrations() can have, taken from its control-flow graph on PHP 8.5.
| When | Instructions | Calls it makes |
|---|---|---|
| always | 14–21 | get_userdata() |
| always | 36–43 | get_userdata(), wp_unslash(), current_time(), email() |
Across PHP versions
| PHP | Compiled | Executed | Branches | Notes |
|---|---|---|---|---|
| 8.6-dev | 44 | 14–43 | 4 | |
| 8.5 | 44 | 14–43 | 4 | |
| 8.4 | 44 | 14–43 | 4 | 3 fewer instructions than PHP 8.3 |
| 8.3 | 47 | 14–46 | 4 | |
| 8.2 | 47 | 14–46 | 4 | |
| 8.1 | 47 | 14–46 | 4 | 1 fewer instruction than PHP 7.4 |
| 7.4 | 48 | 14–47 | 4 |
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.
Uses · 3
- get_userdata()Retrieves user info by user ID.
- wp_unslash()Removes slashes from a string or recursively removes slashes from strings within an array.
- current_time()Retrieves the current time based on specified type.
