Slow Uploads on Gateway API

[rohit-dimagi]

When added requestBuffer setting my uploads become very very slow.

apiVersion: gateway.envoyproxy.io/v1alpha1
kind: BackendTrafficPolicy
metadata:
  name: backend-traffic
  namespace: my-namespace
spec:
  targetRefs:
  - group: gateway.networking.k8s.io
    kind: HTTPRoute
    name: my-namespace
  connection:
    bufferLimit: "64Mi" 
  requestBuffer:
     limit: 200Mi

I also have a client traffic policy.

apiVersion: gateway.envoyproxy.io/v1alpha1
kind: ClientTrafficPolicy
metadata:
name: client-traffic
namespace: my-namespace
spec:
targetRefs:
- group: gateway.networking.k8s.io
  kind: Gateway
  name: gateway-external
  sectionName: secret-store
http2:
  initialStreamWindowSize: 64Mi
  initialConnectionWindowSize: 64Mi

How to correct this? I'm new to Envoy Gateway API.
