wp-admin/includes/plugin.php:74
Description
All plugin headers must be on their own line. Plugin description must not have any newlines, otherwise only parts of the description will be displayed.
The below is formatted for printing.
/*
Plugin Name: Name of the plugin.
Plugin URI: The home page of the plugin.
Description: Plugin description.
Author: Plugin author's name.
Author URI: Link to the author's website.
Version: Plugin version.
Text Domain: Optional. Unique identifier, should be same as the one used in
load_plugin_textdomain().
Domain Path: Optional. Only useful if the translations are located in a
folder above the plugin's base path. For example, if .mo files are
located in the locale folder then Domain Path will be "/locale/" and
must have the first slash. Defaults to the base folder the plugin is
located in.
Network: Optional. Specify "Network: true" to require that a plugin is activated
across all sites in an installation. This will prevent a plugin from being
activated on a single site when Multisite is enabled.
Requires at least: Optional. Specify the minimum required WordPress version.
Requires PHP: Optional. Specify the minimum required PHP version.
* / # Remove the space to close comment. The first 8 KB of the file will be pulled in and if the plugin data is not within that first 8 KB, then the plugin author should correct their plugin and move the plugin data headers to the top.
The plugin file is assumed to have permissions to allow for scripts to read the file. This is not checked however and the file is only opened for reading.

Performance profile
How much work a call to get_plugin_data() 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 67.
Nothing here hands control to plugin code.
12 places in core call this, so the cost is paid more often than your own code shows.
What it touches
- hookthird-party callbacks
apply_filters()one call below get_plugin_data()
Further down the call graph this can also reach query, option, 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 · 8 distinct outcomes
One number would be a lie: the work depends on which branch runs. These are every distinct cost get_plugin_data() can have, taken from its control-flow graph on PHP 8.5.

$plugin_data | 31–33 | get_file_data(), strtolower() |
$plugin_data | 31–34 | get_file_data(), strtolower(), _get_plugin_data_markup_translate() |

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.
