Update:
I just did some poking around and it looks like the problem is in the
sheer amount of data that gets transmitted.
From the index page, if I click on a 2344 bytes e-mail (size of the file
in my Maildir), netstat says that approximately 19kbytes gets sent from
the remote end and another 2kbytes in return. There are obviously TCP/IP
and other overheads in here but I think it's pretty obvious that sqwebmail
is sending a whole LOT of data to display a message.
Simple math says that a 56k modem connection will take nearly 4 seconds
just to transfer all this (ignoring modem and/or software compression -
I am not running gzip).
I saved the raw HTML file from the message body and it is a 19kbytes
file! This is from the original 2kbytes e-mail - that is probably why it
feels so slow.
