It is simpler (for them) to do 1 query rather than 2. @Sheeri

Your "bonus" case is sadly an example of people not thinking, and being lazy in a bad way. How many times does an application do bulk data inserts with a large percentage of duplicate data? Those queries should be written smarter to begin with... These are all very good points….to make it simpler, there are only a few things you can do to write scale your system:

It's a good idea to check your IO thread and make sure you don't have any lag there. Otherwise you can be misled by the fact that Seconds_Behind_Master will sometimes show as 0 in some instances where the SQL thread has caught up to the IO thread and the IO thread is behind (SQL thread only knows about statements that are in the relay log, so if relay log is fully processed and waiting for I/O, as far as replication knows, it's all caught up). On the master issue: SHOW MASTER STATUS On the slave issue: SHOW SLAVE STATUS Compare "File" on Master Status to "Master_Log_File" on Slave Status; "Position" on Master Status to "Read_Master_Log_Pos" on Slave Status.

I really do not need to write another conditional comment for ie6, 7 and now CHROME. I have been using it for a week now and seems to be pretty standard when rendering web pages. The first thing that I have done with Chrome is to look over all previous web site to make sure they render properly.
