iwork 09 vs iwork 08 performance comparison

Running iwork 09 trail vs iwork 08 I get the following activity monitor usage using the same templates.


Pages using blank template

Pages 09:
16 threads
107.02 MB Real Memory
1.19 GB Virtual Memory

Pages 08
14 threads
82.16MB Real Memory
1.15GB Virtual Memory


Numbers using blank template

Numbers 09
10 threads
102.33 MB Real Memory
1.18 GB Virtual Memory

Numbers 08
7 threads
82.17 MB Real Memory
1.14GB Virtual Memory


Keynote using white template

Keynote 09
10 threads
99.14 MB Real Memory
1.20 GB Virtual Memory

Keynote 08
10 threads
113.77 MB Real Memory
1.19 GB Virtual Memory


I ran these tests multiple times and the values were always about the same. The system I am running this on is a quad core, 4 gig ram machine

So what does this tell us? For both Pages and Numbers, the 09 version is a little bit more resource hungary in terms of ram. However, uses more threads, which to my understanding, utilizes the capabilities of multicore processors better and thus, run a little more efficiently. Keynote 09 on the other hand seems to not be as resource hungry from what I can tell.

Hopefully this was somewhat informative as I tried to compare the two versions
