You can check the speed with the 'show interfaces Port-channel1' command. You can use the 'sh int po1' for short. (substitute 1 with your channel group number)
#show interfaces Port-channel1
Port-channel1 is up, line protocol is up (connected)
Hardware is EtherChannel, address is 00d0.0006.0000 (bia 00d0.0006.0000)
MTU 1500 bytes, BW 2000000 Kbit, DLY 10 usec,
Look for the BW part in the output which indicates the bandwidth of the link.
Please note that EtherChannel is load balancing packets between the bundled links based on a configurable hashing algorithm. There might be cases when the traffic is not evenly balanced across your links. For more information I recommend you to have a look at the following guide and look for the specific platform you are using:
Understanding EtherChannel Load Balancing and Redundancy on Catalyst Switches
When a switch drops a packet it can be caused by numerous reasons. Look at the output of the 'show interfaces' command and check which error counter is increasing. Use the following guides as a reference to find out what those counters mean.

i have two switch in my network and connected them thru etherchannel using two fast eathernet channel...
now i want to check actully what data rate end users are getting..as per theory it should be 200 mbps//
please advice me how do i check my speed after implementing etherchannel..
This is a incorrect assumption . Etherchannel gives you a bigger aggregated pipe from which to send ip conversations down , but the way it works for a given ip conversation it will only flow down one of those pipes so your thruput will never be more than 100 mgps . Etherchannel gives you a bigger pipe
for more traffic but that traffic is hashed across a single link per conversation so it will not be more than 100 meg.
It allows you to send TCP or UDP packets between two devices with different traffic rates and packet sizes. You start the program as either a server or as a client. I have used this at multiple ISP to confirm with customers the true speed of leased lines.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
