In my nlog configuration, I've set
<targets async="true">
with the understanding that all logging now happens asynchronously to my application workflow. (and I have noticed a performance improvement, especially on the Email target). This has me thinking about log sequence though. I understand that with async, one has no guarantee of the order in which the OS will execute the async work. So if, in my web app, multiple requests come in to the same method, each logging their occurrence to NLog, does this really mean that the sequence in which the events appear in my log target will not necessarily be the sequence in which the log method was called by the various requests?
If so, is this just a consequence of async that one has to live with? Or is there something I can do to keep have my logs reflect the correct sequence?
