I typically run at 40-50% of (RAM) memory. That includes a browser, a virtual box, Logos5, and assorted Sidebar utilities. When I'm up to 60%, Logos starts dragging, and usually there's a memory leak somewhere. Windows7, 4gig memory, i7, Logos running off an SSD.
And indeed Sidebar utilities leak but measured in 'K's; not megs. Opera leaks but not too bad.
That's when I started watching Logos5. First, I noticed just spinning the text ran up memory with no give-back. (Spinning on a touch-screen is similar to an iPhone ... the spins move text by very quickly).
Then I noticed hooking up a PowerLookup multiplies the memory loss measurably. Again with no give-back.
So Logos5 after a startup with layout and 15 min stablizing, is 630meg and change. Spinning the dials for 10min moves me up to 800meg. And after a few days, I'm solidly over a gig of Logos memory. I tried spinning various resources; some are real hogs.
I'm wondering if this is Logos5 new found source of performance?
