Difficult to give an exact number. However, I would strongly recommend
upgrading your RE-5.0 to the maximum amount of memory, i.e. 768 Mbyte.

M7i is 3.2 Gbps full duplex for its 4 PIC slots, plus up to 1 Gbps full
duplex for the FIC (onboard) slot. So up to 4.2 Gbps, plus whatever you
can push through the builtin tunnel PIC.

M10i is 6.4 Gbps full duplex for its 8 PIC slots. If you need a tunnel
PIC, it counts against these 6.4 Gbps.

Juniper changed the way memory utilization was calculated, see

So RE memory utilization constantly around 95% is pretty normal.
