Thanks Tegan.
Is it applied to all production env?
@chbibo yes production
First off-- thank you for this! Second, OpCache seems to be caching Magento API calls. Any idea how to blacklist or exclude any calls to the API?
If it helps anyone else-- I blacklisted /app/code/core/Mage/Api/* and the API works.Thanks again.
Some more good knowledge being dropped here:

Hi @tegansnyder. This slide was yesterday on a Magento Imagine session given by an Magento employee. You should make some improvements I think.
opcache.memory_consumption=768
opcache.max_accelerated_files=60000
What do you think about it?
@studio2f the correct blacklist path for the API is DOCUMENT_ROOT/app/code/core/Mage/Api/*
or it wont work. e.g. /var/www/htdocs/app/code/core/Mage/Api/*
I noticed you guys are recommending not to cache Magento API calls - can someone help me out with understanding why we make this recommendation? I have a Magento installation and I just setup OpCache. My Magento app connects via API with Salesforce and I am looking to cache anything I can, but I didn't understand why we wouldn't want to cache API? Easy now - I'm a n00b ;)
@brandontamm maybe they mean caching of Api-call "response". Its possible during the Soap-calls, when it gets the same response with the same input-parameters. You can check WSDL-cache and disable, but I think that its not "OPcache" cache. (I could be wrong)
Use for production environments.
Width validate_timestamps disabled you must reset the OpCache manually or restart Apache for changes to the filesystem to take effect. After each code deployment you can login to the Magento admin and goto the OpCache control panel and hit reset cache. Or issue the command line reset by curling a page with something like this:
Note for above to work you need this extension:

Also for those of you using Capistrano or another Symlink based deployment please read this about OpCache:
