I am on a Debian wheezy and would like to speed up curl in php while doing a lot of DNS requests. asynchDNS seems like a good option to be enabled.
This question has already been asked here and unfortunately it did not solve my problem. I indeed compiled curl with c-ares (and also tried with the threaded-resolver), following curl.haxx.se but it did not change the output of my phpinfo
which still displays asynchDNS => no
.
Also, while executing ./configure --enable-threaded-resolver
for curl, I get the confirmation resolver: threaded
for the build of the program and don't see any changes afterwards.
Did anyone manage to have asynchDNS enabled and if so, how ?
