How to increase the "rspinfo data buffer"?
 
The as5400xm is taking 15seconds to download a 300k audio file.  Seems to be using very small chunks.
 
as5400xm is in Hong Kong, media server is in Los Angeles.  Several identically configured as5400xm in Los Angeles work fine.
 
 
I am seeing the following unusual http log output:

Hi Anusha,

Thanks for your response.

The issue is slow downloading, not caching. Caching is working fine with my existing settings:

http client cache memory pool 100000
http client cache memory file 10000
http client cache refresh 684000

How to increase the "rspinfo data buffer" ?

Thanks,
Travis

Hi Travis,

Our Engineering team responded to your query saying the chunk size is controlled by HTTP server side, not on our client side. BTW which HTTP server are you using? Is it IIS or Apache?

Thanks,
Anusha

Here is "debug http client all": This doesn't display the error, but it does show all headers. I don't see any headers that refer to chunk size.
