63.3 MiB + 14.7 MiB = 78.0 MiB epiphany
83.0 MiB + 16.6 MiB = 99.5 MiB evolution
If that doesn't help e-mail me offline because I would love to work with
you to find the difference between my setup and yours.
I can imagine the epiphany memory usage IF you have a lot of tabs
open.. but evolution..?? what where you doing there?
