Excessive memory usage about awspricing HOT 2 OPEN

Agreed that it'd be great to cut down on memory usage! Have you been able to give v2.0.0 a try yet? That should hopefully help a bit, but open to PRs to improve this further.

Hi @garrettheel

Issue

The memory issue still exists and gets worse everytime AWS adds more instance types I guess ;-). Right now my script uses up to 9.5GB of memory. By tracing it with py-spy I can see the CPU is heavily used to decode JSON and I suspect the memory is used by all the dict objects resulting. While it was bearable a year ago now my i7 / 16GB Macbook pro 2015 comes to almost to halt for 30sec because of my script running with the following line and often I have to kill firefox to have enough memory to run it otherwise it fails with a MemoryError

Code

offerings = conn.describe_reserved_instances_offerings(MaxDuration=MaxRiDuration * 2592000,InstanceTenancy='default')

Questions

Is there any possible workaround to use less memory? and as a bonus less CPU... Other than buy a new laptop ;-)

Environment

• Python 2.7.12+ (Debian)
• awspricing (2.0.3)
