I just installed J2SDK 1.5-beta1 on my Windows 2K PC (current MS patches). It takes a very long time (> 5 minutes) for the real user dialog to come up, the system is busy doing disk I/O.
Examining the situation using FileMon (http://www.sysinternals.com/ntw2k/source/filemon.shtml) most of the time seems to be consumed unpacking j2sdk-1_5_0-beta-windows-i586.exe into c:\temp\..., which is done in reads/writes of 1024 byte. A bigger buffer should be used to speed things up.
Of course, the files are then copied again for some reason from c:\temp\... to "C:\Documents and Settings\$user\Local Settings\Application Data", which does exactly speed things up either. That is done in 64k chunks, though, so it is not quite as slow.
