[Geocoding] Increasing requests per second

[Mark Davies]

Hi All

I'm currently in the process of trying to improve the amount of geocodes
per sec

I have the whole world on nominatim but only currently using a handful of
countries
Its running on 48gb ram and SSD's and is topping out around 62 per second
with max CPU
I know it needs at least 96gb ram however my question is regarding scaling
and if its even possible to get near what I want

My target is 500 per second.
I'm first wondering if this is a possibility, even with 128+ram
I know there are many factors like similar cached requests etc, but someone
might know if there is a limit on what nominatim can handle so I can adjust
my expectations.

Also if there is a better solution for reverse geocoding with road speed
data (extra_tags)
Thanks!
