Well I assume either way would work, is there that big of performance hit by using sql_query?
That depends on how long the INSERT statement takes to return. :-) In principle, it shouldn't be a big deal.
sql_query_async() is just a wrapper around something very similar to the mqueue/rtimer example I gave in the previous post. It's just more streamlined.
As far as whether there's a performance hit, that's a complex discussion. Any external I/O wait incurs some delay, but whether it's significant or whether it's worth doing anything about it is hard to say.
As it happens, I just wrote an article on this topic last night:
