router 4331 performance?

[baselzind]

I read somewhere that 4331 router performance is 100mbps however currently i have 4331 and 500mbps internet speed from isp. So how am i able to get 500Mbps speed if the router performance is 100Mbps?

This can be obtain through boost license, 

please check

correction it is 4431 not 4331 , so a 4431 router hardware is able to provide 1G internet speed?

4431 with Aggregate Throughput (Performance License)can reach 1Gbps

Hello,

the default throughput of the 4431 should be 500Mbps. You can check what your current throughput level is with the exec command:

4431#show platform hardware throughput level

The output should be something like this:

The current throughput level is 500000 kb/s

As @Shambhu-Kumar said, the Aggregate Throughput (Performance License) gets you to 1G, the Boost License gets you to >4G.

The thread linked below has a table that lists the license options for the various models:

@Shambhu-Kumar is totally right it depend on license.

As the other posters have noted, your 4431's performance (like other ISR 4Ks) is limited either by license or the overall capacity of the router (with a, as also noted, boost license).  Note, the basic and performance licenses usually "guarantee" a level of performance.  The boost license just removes the artificial performance limit and you get whatever the router can deliver (which can be very variable performance [basically the same as earlier ISR gens]).

As also noted by another poster, to support 500 Mbps bandwidth (duplex - correct?), on a 4431 you'll need at least the performance license.

PS:

BTW, if your 4431 has the basic license for 500 Mbps, you might try it on your upgraded circuit.  My understanding is the license shapes traffic, i.e. transient bursts might only be delayed, not dropped, and do your really expect to use more than 500 Mbps, aggregated, often?  If not, you might be fine, at least for now, using your router with a basic license.
