Hello,
I have an NSTableView with about 400 rows and four columns.

Should I use NSMutableData to avoid all the alloc/init messages to NSNumber to speed up my code?


With only 400 rows you needn't worry about the speed of NSNumber creation.

It makes sense that I don't need to worry about speed with only four hundred rows. It just seems like good practice to avoid or minimize allocating memory in any loop. I have three or four other dictionary keys that also require release and alloc/inits messages to be sent. Also, I have another table that I'm about to start working on that will have 25 to 40 thousand rows. I'm wondering at what point I need to worry about the speed of these release and alloc/inits messages.
