Webflux/Angular slow Server side events vs http-client
0
I am running a demo locally with angular and webflux hitting a webflux endpoint which returns 3 photos with size ~ (20MB, 1k, 20MB) from db
The difference on timing using http-client and SSE on angular service are huge, am i missing something here?
spring controller
@RestController
public class PhotoController {
@GetMapping(value = "/photos")
public Flux<Photo> getAllPhoto() {
return photoService.findAll();
}
}
Angular service
getWithGET(): Observable<any> {
return this.http.get(this.URL);
}
getWithSSE(): Observable<any> {
return Observable.create(obs => {
const es = new EventSource(this.URL);
es.addEventListener('message', (evt) => {
obs.next(evt);
});
return () => es.close()
});
}
angular component
clickGET() {
this.requestsService.getWithGET()
.subscribe(
data => console.log(data);
}
clickSSE() {
this.requestsService.getWithSSE()
.pipe(take(3))
.subscribe(
message => console.log(message );
}

@piotrszybicki there is one request with first service and one with second , the getWithSSE is much much slower than getWithGET, both requests bring back same data (3 objects with size 20MB, 1k, 20MB)
