If you don't want the login scripts to run, don't use the --login flag when
you invoke bash.
Also, try adding the -x command when you invoke bash, so you can see what
happens when it starts up, which scripts are running, and whether any of the
commands they execute are particularly slow. It might be one of the
/etc/profile.d scripts.
