Cisco 881 Router with 10 Mbps WAN?

Will I face any performance issues if I use a Cisco 881 Router with WAN speeds upto 10 Mbps? I am more interested in knowing the effects on Hardware Resources such as CPU Utilization & Memory Utilization which is the primary concern of my customer. The customer traffic is consistently expected around 8-10 Mbps during business hours which will put lots of strain on the resources however due to limited budgets the 800 is more preferred over 1900.

880 is rated to push 25.6

880 is rated to push 25.6 Mbps (single-direction traffic, no encryption).  


Half the value of 25.6 and you'll get a rough estimate of a simultaneous two-way traffic (download and upload) but without any encryption.  


My recommendation is to load the DRAM and Flash to it's maximum.

The 881 might be overstressed to support up to 10 Mbps (duplex).

Have you've also consider the 890 series?

I've attached a Cisco whitepaper that details ISR performance in different situations.
