Solaris 11 vs rootsh

Hi all -- I've been using rootsh for long time now to log shell input/output. 
I use it on my Solaris 10 x86 boxes as well as RHEL 6.2 and haven't ever had a 
problem. I am in the process of migrating to solaris 11 and have found that 
rootsh is very sluggish; interaction with the shell is almost like doing over 
an old 9600 baud modem, both input and ouput. What gets logged is correct, 
it's just slow.

Anybody out there familiar enough with rootsh to offer a suggestion?

Thanks,
Jody Baze
