---------------------------------------
Summary: Libcloud linode driver is extremely slow due to v6 curl
call
Key: LIBCLOUD-539
URL: https://issues.apache.org/jira/browse/LIBCLOUD-539
Project: Libcloud
Issue Type: Bug
Components: Core
Affects Versions: 0.14.0-beta3
Environment: macOSX
pycharm 2.7.3
Reporter: dustin oberloh
Priority: Critical
When I attempt to use the Linode driver. Things like list_nodes and list_images
are taking FOREVER. From what I understand, curl uses v6 by default if it can.
So I tried a couple things:
After turning debug on, I tested the vanilla output:
curl -i -X GET -H 'Host: api.linode.com' -H 'X-LC-Request-ID: 4492557272' -H
'Accept-Encoding: gzip,deflate' -H 'User-Agent: libcloud/0.14.1 (Linode) '
--compress
'https://api.linode.com:443/?api_key=xxxxxxxxxxxx&api_responseFormat=json&api_action=avail.distributions'
And then the same curl except with the v4 flag:
curl -4 -i -X GET -H 'Host: api.linode.com' -H 'X-LC-Request-ID: 4492557272' -H
'Accept-Encoding: gzip,deflate' -H 'User-Agent: libcloud/0.14.1 (Linode) '
--compress
'https://api.linode.com:443/?api_key=xxxxxxxxxxxxx&api_responseFormat=json&api_action=avail.distributions'
There is a drastic difference in the time it takes to execute the call. Linode
driver should use the -4 flag for all calls.
