Can you tell which ATS version you are running and if you are using any plugins
(custom or otherwise)?
Assuming you are not running any plugins, typically the latency on ATS should
be mostly in connection establishments (both incoming and outgoing).
Your config does seem to enable persistent connections, so, that's good (you
may consider tuning the timers a bit depending on your use case though).
- CONFIG proxy.config.http.keep_alive_no_activity_timeout_in INT 30
- CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 60
Depending on the version you are running, you will need to enable server
session sharing to make better use of persistent connections on the outbound
side. On the latest version, the settings you would need to play with is server
session sharing pool. The default value for this setting is "thread", which
enables a per thread pool and in some cases (depending on the origins), this
has been known to increase the need for more outbound connections (and
latency). You may try checking if setting this to "global" helps.
Additionally, (again depending on which release you are running), you may
consider enabling SPDY (and/or H2) to support request multiplexing. Most
popular browsers support one or the other or both and at least one of these is
enabled in several prod deployments.
H2 is out-of-the-box (although, not widely prod deployed/used yet), if you are
running the latest version (6.0+). To enable H2, you will need to set
proxy-config-http2-enabled. To enable SPDY, you will need to build
trafficserver with spdylay as outlined here..

Hi,
I recently migrated away from Squid to ATS, while it fixed a lot of
long-standing bugs we had with Squid, we encountered an issue with download
speeds, by which it is 2-4x slower.
Any recommendations on what I need to configure correct to fix the slow
download speeds with ATS?
Here's my records.config: http://pastebin.com/kPb2T4Gj
Thanks!
