eshell calls `start-file-process' (see `eshell-gather-process-output')
for every single command , which is an asynchronous process. Tramp opens
another connection for asynchronous processes, what you see.
shell calls once `start-file-process' ("/bin/sh -i"), and lets execute
all commands inside this process. That's why it is much faster.
I fear it cannot be changed, because eshell is more flexible than
shell. You could do
~ $ cd /scp:remotehost:
/scp:remotehost: $ hostname
remotehost
/scp:remotehost: $ cd /scp:anotherhost:
/scp:anotherhost: $ hostname
anotherhost
/scp:anotherhost: $
This is not possible with shell.
