Do you have a lot of sparse files and are you doing sparse file processing? If so, it seems (based on one of my systems) that you can end up CPU-limited as the bacula-fd goes through reading a lot of zeros as fast as it can. Other than that, do you have a lot of files on the Solaris machines, particularly a lot of files in a single directory? Reading a lot of distinct can noticeably slow down backups and I've noticed it on Solaris on filesystems like webservers full of small image files or mail spools with file-per-message filestores.
