#61202: squid 4.13 HTTPS Sites Extremely Slow
-----------------------+--------------------
 Reporter:  essandess  |      Owner:  (none)
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.6.3
 Keywords:             |       Port:  squid4
-----------------------+--------------------
 squid 4.13 is extremely slow when accessing TLS-secured sites.

 Does anyone else observe this issue?

 Troubleshooting, using the configuration
 {{{/opt/local/etc/squid/squid.conf.default}}}, with and without the
 directive:

 {{{
 always_direct allow all
 }}}

 I don't see any issues in {{{access.log}}} or {{{cache.log}}}.


 Comparing Privoxy to squid download times using {{{curl}}}:

 Privoxy proxy download time:
 {{{
 time curl --proxy localhost:8118

   % Total    % Received % Xferd  Average Speed   Time    Time     Time
 Current
                                  Dload  Upload   Total   Spent    Left
 Speed

 682k

 real    0m0.784s
 user    0m0.019s
 sys     0m0.018s
 }}}

 Squid 4.13 proxy download time (times out with curl, eventually loads
 using Safari):
 {{{
 time curl --proxy localhost:3128
 https://www.youtube.com/watch?v=dQw4w9WgXcQ 1> /dev/null
   % Total    % Received % Xferd  Average Speed   Time    Time     Time

 Speed

 }}}

 On the other hand, HTTP access is very fast:

 {{{
 time curl --proxy jacquard:3128 http://earlyconifers.myspecies.info 1>
 /dev/null
   % Total    % Received % Xferd  Average Speed   Time    Time     Time

 Speed

 }}}
