Client/server environment. Server is connected to a Cisco hub. I took traces and I see about 150 packets retransmitted by the server side. Client displays 14 packets retransmitted. Performance is lower than expected. The server network interface card is logging Tx errors.
Does the retransmission could be generated by a busy hub?
I know that errors in interfaces can be caused by a faulty port, bad cable or speed/duplex mismatch.
Someone claimed that a busy, congested hub could be capable of generating such errors and retransmissions. Can someone confirm that claim?
