Since upgrading my Solaris9 server to MySQL 4.1.9 (previously 4.1.3), remote connections to it from my WinXP laptop have become very slow.

Remote connections using the mysql command-line tool (4.1.7 client), MySQL Query Browser (1.1.5) or JDBC connections with Connector/J (3.0.16) used to all connect immediately. Now they take anywhere from 10-30 seconds. The Query Browser has also become very frustrating because every time I execute a query it freezes for 10-30 seconds before finally executing each query.

I have noticed that on the server during this long wait time, my new connection appears immediately, but mysqladmin processlist shows the user to be "unauthenticated user" until it finally completes the connection (and updates the user to the correct username). So, I'm not having network problems getting to the server or anything like that. Also, the server is not low on memory, low on connections, is not producing any errors, etc. Via Google I found a few occurrences of others with "unauthenticated user" issues, but they all seem to involve lots of connections in this state. In my case it's only one--the user very slowly connecting.

This has been happening since a recent server update to 4.1.9 and never happened previously with 4.1.3. Also, it does not occur when making remote connections from the same PC to a 4.1.7 server.

Any suggestions?
