Silly question... why do this just at the request caching level?
I had a bit of a deep dive into our caching strategies yesterday to get myself back up to speed...
Is it slower to fetch a key from Memcached once (to populate the L1 per request) than it is to fetch it from MySQL (to populate the same L1 per request)?.. or am I totally misunderstanding our caching code?
The TCP speed is probably comparable although the MySQL is going to be doing some disk I/O while Memcached is all in memory so in theory Memcached should be faster, but the difference might be imperceptible with a low load and good disk*?
MySQL will be doing disk I/O on the first request for the same thing. I'm pretty sure the caching strategy in MySQL is far better than ours and memcached. -- You are receiving this mail because: You are watching all bug changes.
