## Calculating Throughput on the ASA

Community Member

Problem:

Calculating Throughput on the ASA

Solution:

For Calculating Throughput on the ASA,  We have to add received or Transmit  traffic in bytes/sec on all physical interfaces:

26066000 + 23001 + 12071002  = 38160003 Bytes/sec

Then you will need to convert that to Mb/seconds for that you will need to partition that into 1024 to get the kbps and then the

result into 1024 again to get the Mbps.

38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)

Example:

ASA# sh traffic

Outputs (which we calculated in order to get the throughput):

26066000 + 23001 + 12071002  = 38160003 Bytes/sec

38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)

Why

38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)

?!?

Storage (Kilo = 1024 bits)
Bandwidth (Kilo = 1000 bits)

http://physics.nist.gov/cuu/Units/binary.html

so

38160003 = megabits 305.280024

Hi Azmat Ali,  I am getting below different values for recvd and transmit, which one to be considered here ?

 Traffic bytes/sec Mbps recvd 38160003 291.1377 trasmitt 103252006 787.7503

Hello azali and all:

Is not this wrong equation?

38160003*8 = 305280024/1024*1024 = 291 Mbps(Approx)

it should be

38160003*8 = 305280024 bits = (305280024/1000) Kbps = 305280.024/1024 = 291 Mbps(Approx)   notice I removed  *1024  which I think is confusing and move bits to Kbps so result will reflect Mbps

There is also some documentation that indicates  1000Kbps = 1Mbps    and other  1024Kbps = 1Mbps

Please note: "Decimal multiples" not Binary  or when it is Binary related.

Refer to: "Decimal multiples" not Binary.

1 kb/s = 0.0009765625 Mb/s
1 Mb/s = 1024 kb/s
