How to change the number of allowed concurrent endpoint calls

My SPA web client has a page that makes ~30 requests simulateously to the same (light) endpoint in my REST API (.Net ASP Core 6).

Currently, my configuration seems to only handle 5 concurrent requests at a time, the others are in a queue. The consequence is a very slow user experience and under usage of my server resources (CPU mainly).

I have not (as far as I understand it) configured anything explicitely. My guess is that 5 is the default setting.

The Host builder is using default values:

public static IHostBuilder CreateHostBuilder(string[] args) =>
            .ConfigureWebHostDefaults(webBuilder =>
            .ConfigureLogging(logging =>
            .UseNLog();  // Setup NLog for Dependency injection;

The web.config file does not have any specific config regarding the topic at hand:

<?xml version="1.0" encoding="utf-8"?>
                <requestLimits maxAllowedContentLength="209715200" />

My PUT endpoint is fairly basic:

public async Task<ResultDto> GetFoo(int id, QueryDto query, CancellationToken cancellationToken) { ... }

I found lot of resources regarding legacy ASP.Net but nothing of value for ASP Core 6 (eventhough this answer confuses me)

How can I configure ASP Core to allow more concurrent requests of the same endpoint?

PS: I experience the same limitation to 5 concurrent requests in both localhost and when deployed on Azure AppService (linux).
