Every time I run this plugin, it takes at least a minute to get anything back. Each time it is execute I can see a new cache being built inside ~/.ansible/tmp. Has anyone else had this problem?

$ time ./ec2.py --refresh-cache \> /dev/null

real 1m30.124s

user 0m3.784s

sys 0m0.357s

$ time ./ec2.py --list \> /dev/null

real 1m17.029s

user 0m3.692s

sys 0m0.334s

$ time ./ec2.py --list \> /dev/null

real 1m36.347s

user 0m3.783s

sys 0m0.381s

$ env|grep INI

EC2\_INI\_PATH=/etc/ansible/ec2.ini

$ egrep ‘cache\_path|cache\_max\_age’ $EC2\_INI\_PATH

cache\_path = ~/.ansible/tmp

cache\_max\_age = 3000

You can probably reduce some time by setting the region that expect your resource to be in and one or note tags in the ex2.ini file

What’s the point of the cache then if it doesn’t re-read the cache?
