Re: How to find the bottleneck?

[Anne Blankert <anne.blankert () geodan nl>]

* Are you sure the branch has a 1 GB/s connection to HQ? 1GB/s possible,
but quite good for current standards.
* The network is as slow as the slowest link. Are you sure that the slowest
link between the branch client and HQ server is 1GB/sec? If traffic is
routed over public internet between branch and HQ, there are likely some
bottlenecks beyond your control
* Is there network latency between branch and headquarters? Even on high
bandwidth connections, network latency can cause low data transfer rates
because some protocols are very chatty: the next packet is sent only after
receiving acknowledgment for the previous packet. With high latency
networks, this may result in sometimes very poor transfer speeds
