Profiling indicates that most of that time is spent in the `escape_bytes` function in `converters.py`.  Here is that function for reference.\n\n``` python\ndef escape_bytes(value, mapping=None):\n    # escape_bytes is calld only on Python 3.\n    return escape_str(value.decode('ascii', 'surrogateescape'), mapping)\n```\n\nWhen I performed the same insertion through another interface, the escaping was about 100 times faster.  \n\nIs there a way to speed this up?\n","author":{"url":"https://github.com/dimitri-yatsenko","@type":"Person","name":"dimitri-yatsenko"},"datePublished":"2015-08-12T17:40:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":27},"url":"https://github.com/366/PyMySQL/issues/366"}
