Question on stratum vs getwork

Hello all,

I am currently mining on Slush's pool and using the Slush's mining proxy. I am unsure about if the proxy is setup to automatically run stratum or do I need to change it? Currently I have my Block Erupter cubes setup for port 8332 and just open the proxy with no need for a .bat file. This is what the proxy reads:

2013-12-30 23:40:38,530 INFO proxy getwork_listener._on_authorized # Worker 'jbbasics.worker1' asks for new work
2013-12-30 23:40:38,539 INFO proxy getwork_listener._on_authorized # Worker 'jbbasics.worker1' asks for new work
2013-12-30 23:40:38,549 INFO proxy jobs.submit # Submitting 6c0be921
2013-12-30 23:40:38,549 WARNING proxy getwork_listener._on_submit # [0ms] Share from 'jbbasics.worker1' accepted, diff 71

I am wondering if it is using getwork vice stratum? Excuse my ignorance on this subject...I have read a few things on stratum vs getwork and still haven't really wrapped my head around it. As far as I can tell stratum is suppose to be better using less bandwith, faster mining, and easier on the server. Please correct me if I am wrong on this.

Do I need to make a .bat file for running stratum such as:

.\mining_proxy.exe -o stratum.bitcoin.cz -p 3333

I seem to be getting my expected hashrate but just wanted to make sure I was optimizing the miner. Thank you for your help in advance!
