• How much is the database being read from vs written to?

  - by Bill Paetzke

  I'd like to determine if my web app is read-heavy, write-heavy, or somewhere in between. I could take a guess, but I want proof. Is there a query I could run in Sql Server 2005 that would tell me the overall read/write ratio? Are there any caveats I should be aware of? Perhaps it can be found in a DMV query, or the Performance Dashboard, or…

I am using Prototype 1.6.0.2 for ajax requests. Is there something I am missing? Most of the write-ups seem to imply that this should work by default.

• maven project with netbeans compiles fully on every run

  - by Jeff Storey

  I was experimenting with Netbeans 6.8 (I'm currently an Eclipse user) because I like having a profiler built into the IDE. It seems that for maven projects, netbeans does a full compile (it invokes process-classes) every time I try to run the project, as opposed to Eclipse, which uses the incremental Java compiler. Is there a way to avoid…

  I noticed that Kohana 3 ORM runs a "SHOW FULL COLUMNS" for each of my models when I start using them: SHOW FULL COLUMNS FROM `mytable` This query might take a few clock cycles to execute (in the Kohana profiler it's actually the slowest of all queries ran in my current app). Is there a way to help Kohana 3 ORM to speed…

This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be…
