The GeoIP composer library (maxmind/geoip-api-php), which is required when using the MaxMindBinaryProvider, includes several files for every request (NOT lazy):

• /geoip/geoip/src/geoip.inc
• /geoip/geoip/src/geoipcity.inc
  • /geoip/geoip/src/geoipregiovars.inc
• /geoip/geoip/src/timezone.php

This is a know issue, that the maxmind team chose to not fix (cf maxmind/geoip-api-php#8).

This adds between 2 and 4ms in production to every request (with APC enabled). The only way to avoid that is to remove the dependency to the GeoIP composer package, which forces the loading in its composer.json:

    "autoload": {
        "files": [
        "src/geoip.inc",
        "src/geoipcity.inc",
        "src/timezone.php"
        ]
    },

In my opinion, this justifies a more complicated installation procedure for the GeoIP provider.
