Safari 2.0's memory usage is very similar to Safari 1.3 in Panther for me. It hovers around 55 MB with two windows open. As for Dashboard, my current widgets are using: Weather: 8.73 MB Calendar: 9.05 MB Calculator: 5.36 MB Maybe a reboot would help? My home Mac only has 448 MB of RAM, and Tiger's been extremely smooth and fast! You’re not misreading Activity Monitor, but it seems odd your memory usage is so high.

Seems like something's a bit leaky... Now, is there any way to relaunch the Dashboard without logging out? (ok... I'll reboot the laptop in the morning :-) ) I just relaunched Safari, and it’s “real memory” footprint dropped to 33MB.

But a I have to say, widgets are at least very virtual memory hungry. I have only 4 weather widgets running. They each take up about 7-10MB of real RAM. That's cool. But they also each eat up over 100MB of virtual memroy. What's up with that. I'm not a programer, just a lowly admin. But that VM usaage seems aweful high. Than goodness for 2GB of RAM and fast drives on my G5 at work. I seriously doubt I'll fare as well on my G4/466 with 768MB of RAM at home...... I don’t seem to have the numbers you have.

Get iPulse or some other monitor to check real vm disk access... you will see the disk is not being used for swapping at all under normal circumstances (about 50-100 MB of free RAM). To be honest I don't know why the OS "reserves" so much vm for each app... but it's clear that it is not used. I realized this when the total vm size was bigger than my unused disk space. :) But Tiger clearly uses more RAM than Panther did... at least it qualifies a lot as "unused". Anyone with more understanding on this field? salut Relax about that virtual memory (vm) listings, check the swapfiles at /var/vm/, most probably (if you have some RAM still free) there will be only one swapfile (swapfile0) of size 64MB, which is kind of default and is created on startup.
