I went down http://squirrelmail.org/wiki/SquirrelMailPerformance exploring the various solutions. I decided to try an imap proxy (http://www.imapproxy.org). This completely solved the problem. The docs for impproxy point out that webmail clients, like SM, log in to imap for each page. That gave me the idea to try imapproxy. I don't really know why it helped so much, since my telnet login to my imap server (which runs as a daemon) was fast. But it does work!
