After having many deadlocks due to a high order volumne I've applied the these fixes to the core. Some can be found in a Magento forum. Before the fixes we could only process 1 order every 5-10 secs. Updating to Magento 1.8 is currently not an option but in 1-2 months.

1st Deadlock

Mage_Sales_Model_Abstract::_afterSave must be removed and replaced with afterCommitCallback. This is important to move the grid update (of sales_flat_order_grid) out of the transaction.

2nd Deadlock

Rewrite the method of the Mage_CatalogInventory_Model_Observer::reindexQuoteInventory() to remove the price reindexing from the transaction. That index process will also be fired in event sales_model_service_quote_submit_success.

Configuring nginx for SSL SNI vhosts

Gotchas

• Note that SHA2 hash algorithm may be not supported on older systems (Windows XP, Windows 2003, among others).
• Be aware that mandatory https on SNI vhosts eliminate [Internet Explorer on Windows XP, among others] (http://en.wikipedia.org/wiki/Server_Name_Indication#Web_browsers.5B6.5D).

Remarks

• My version of konklones SSL config does not have SPDY support(my nginx+openssl does not support it)
• You need a default ssl server (example.org-default.conf).
• Some SSL-options have to be unique across your instance, so it's easier to have them in a common file(ssl.conf).
