Updates in bulk rather than in real time (Subscription - Angular 17)

[adriano-tumino]

Hello everyone, I'm having issues with subscriptions for graphql.
I created the subscription in Apollo by following the instructions in the documentation however, I receive bulk updates (three updates simultaneously) rather than individual updates, and they happen considerably more slowly (every 2 seconds or so) than what the graphql interface shows (one update per second). I attempted to alter the cache management, but I got no results.
The data I'm supposed to display is updated much more quickly than this (I'd like to go up to 10Hz refresh).

Could you please assist me? Many thanks for that

app.config.ts:

 export const appConfig: ApplicationConfig = {
    providers: [
        provideRouter(routes),
        provideAnimations(),
        importProvidersFrom(HttpClientModule),
        Apollo,
        {
            provide: APOLLO_OPTIONS,
            useFactory(httpLink: HttpLink): ApolloClientOptions<unknown> {
                const http = httpLink.create({
                    uri: apiUrl
                });

                const ws = new WebSocketLink({
                    uri: apiWsUrl,
                    options: {
                        reconnect: true
                    }
                });

                const link = split(
                    ({ query }) => {
                        const definition = getMainDefinition(query);
                        return (
                            definition.kind === Kind.OPERATION_DEFINITION &&
                            definition.operation === OperationTypeNode.SUBSCRIPTION
                        );
                    },
                    ws,
                    http
                );

                return {
                    link,
                    cache: new InMemoryCache({
                        resultCaching: false,
                    })
                };
            },
            deps: [HttpLink]
        }
    ]
};

entity.service.ts:

this.apollo
  .subscribe({
    query: ENTITIES_UPDATE,
    fetchPolicy: "no-cache",
  }) .subscribe({
     next: (data) => console.log("NEXT: ", data),
     error: (err) => console.log("ERR: ", err),
     complete: () => console.log("Complete")
  });
