Does Retrofit or OkHttp limit number of parallel requests?

I use RxJavaCallAdapterFactory.create() and Schedulers.io(), so Dispatcher isn't used and maxRequests and maxRequestsPerHost not a problem. Schedulers.io() creates infinite number of threads.

The problem is when I run 10 requests and then 1 more while previous not finished this 1 request takes longer time to start. If 10 requests finished the next request run immediately. When I have a several requests running I see in logs that Call.execute() is called and then request started only after 6 seconds. When there are no active requests, new request starts immediately. So is it limitation of android or some network libraries?

Yes, configure this in OkHttp’s Dispatcher.

Use OkHttp Dispatcher.

Dispatcher dispatcher = new Dispatcher(Executors.newFixedThreadPool(20));
dispatcher.setMaxRequests(20);
dispatcher.setMaxRequestsPerHost(1);

OkHttpClient okHttpClient = new OkHttpClient.Builder()
   .dispatcher(dispatcher)
   .build();

Retrofit retrofit = new Retrofit.Builder()
   .baseUrl(HttpUrl.get("https://example.com/"))
   .client(okHttpClient)
   .build();
