We're troubleshooting some slow site transactions on our site. We've see requests to index.php that are loading slowly.

NewRelic shows a big lag in response from XF\Http\ResponseStream: output, where it took 36,400 ms for this function to respond.

I think it might be related to the fetching of attachments from and external object storage service, but the calls to the object service seems to be successful.

Anyone else experience this or something similar?
