Brandon,

It seems Steven has deleted mine and his own comments on his site. So what other “MM tuning guru’s” have mixed reviews?

it would be nice if he commented what was incorrect especially since i made him aware of the subject originally. oh well. anyways i have a much more detailed document ill put up in a couple of weeks that explains more about the heap etc.

Hey Robi, Thanks for stopping by. I found your post to be informative myself, and it was among the first on ColdFusion MX tuning in general. For an example of what I was referring to, check the comments section here.

So what exactly do you have issues with or do the “gurus” have iusses with with my article?

Tom:

Thanks for the links. I also added a few other Java specific resources.

Steven:

Good point about the post configuration– that reminds me of at least one blog entry I need to write sometime. I added a link to setting up different JVM arguments for different instances as that was one thing which it reminded me of.

Pete:

Thanks!

Well done Brandon. Nice survey of clustering and performance related articles. I usually turn to Brandon Purcell’s (and Frank DeRienzo’s) articles for architectural considerations of complex clustering scenarios, and to Pete Freitag’s articles for JVM and GC tuning information.

Clustering in CFMX 7 has abstracted much of the guts of how to set up a cluster. Where CFMX 6.1 was much more hands on tinkering, CFMX 7’s Enterprise Manager and Instance Manager make setting up clusters much more practical and intuitive, and its not absolutely necessary to know all the details found in Purcell’s early articles unless you want to have a more academic understanding of how it works. There remain some features I’d like to see regarding better post-configuation mangement of JRun/CF clusters, but cluster configuration in CFMX 7 should be substantially easier than CFMX 6.1.

Good job! And you’re right. Learning to tune ColdFusion isn’t easy or something you can do in 10 minutes or a day.

A couple good links on GC:
