Asked by: bowemc

Hi,

I have a chunk of code which seems to be running pretty slowly. There is several methods, queries etc. I was wondering is there any good free tools I can download to analyze my VBA code to see where the bottlenecks might be?

Thanks

I'm not aware of any free ones. I think people tend to just put timer statements in the code and test.

It's usually pretty easy to check yourself.  

Common ones to look for are queries that return a lot of data, or don't use native functions.
Very long loops (for or while)
lots of references to the sheet

You can comment out sections and see how it effects performance to narrow it down too.  (Or use a timer and output the time when each section is executed)

You can try turning off auto calculate, and screen updating.  
Also make sure you're not running out of RAM.
