Performance tuning of Nominatim

[kerchner]

Hello,

Is there any documentation providing guidance on Nominatim server sizing - number of cores, etc.? Is Nominatim designed so that it takes advantage of parallel processing and multiple cores? I'm looking for ways to speed up the geocoding API.

Thanks!

For the API Nominatim acts like other PHP web apps, each process will only deal with one incoming request. The usual scaling is to add a PHP accelerators like php-fpm. Then you can max out all CPU cores. See #1290
