          segmap_percent is set to 12% by default. Solaris 10u7(x64) / 10u8 (sparc) added Vnode Page Mapping (VPM) so vpm_cache_percent should be change instead. The default for segmap_percent was changed to 6%.

          'kstat -n segmap' is a good starting point but try referencing to the following document.
