Hi,

I recently migrated away from Squid to ATS, while i= t fixed a lot of long-standing bugs we had with Squid, we encountered an is= sue with download speeds, by which it is 2-4x slower.

Any recommendations on what I need to configure correct to fix the s= low download speeds with ATS?

=
Is this data chunked encoding? There has been report = that increasing

proxy.config.http.chunking.size


can help with performance when proxying chunked data.
