one word: encryption
whenever you encrypt something it takes the firewalls more time to analyze
the packets and decrypt them, thus slowing the transfer time down. use the
lowest level of encryption for fastest network speeds.
Look at this link ==>
http://telephonyonline.com/wireless/mag/wireless_lock_key/
There is a paragraph in there that answers your question directly:
"ENCRYPTION & THROUGHPUTThe downside to adding another level of encryption
is that it affects network performance. Data encryption can affect data
throughput depending upon the data-encryption scheme, and your network data
speeds can suffer. For example, CDPD systems start out with a raw data rate
of 19.2kb/s. By the time you add in the overhead for TCP or UDP for
transport and your own data encryption, the data throughput is about 10kb/s
-- a loss of about 50%. If you add application-level data encryption, the
throughput could fall even further."

Hi All,
We have installet Endian Comunity 2.1. in two diferent places.
When I download a file from Internet from place A, I donwload it at 600
Kbps, and from place B I donwload it at 500 Kbps.
Both connections are symetric (8Mb upload/download)
But , when I connet the two places with a net-to-net ipsec tunnel, and I
try
to transfer some files from place A two place B , only transfer at 150
Kbps
more or less.
Why ?
Can someone help me please ?
Thanks a lot.
