Power Load Average and Lwps

Code:
NPROC USERNAME  SWAP   RSS MEMORY      TIME  CPU                             
   320 oracle     23G   22G    69% 582:55:11  85%
    47 root      148M  101M   0.3%  99:29:40 0.3%
    53 rafmsdb    38M   60M   0.2%   0:46:17 0.1%
     1 smmsp    1296K 5440K   0.0%   0:00:08 0.0%
     7 daemon   7368K 7392K   0.0%   0:08:35 0.0%
Total: 428 processes, 8117 lwps, load averages: 14.96, 15.73, 16.51

Above ouput is taken from prstat -a on sun database server.Kernel is 5.10 Generic_127127-11. Hardware is Sun-Fire-V890.

1) Can any one tell me why the load average is so high though the cpu utilization is 85%.
2) what is lwps and is it harmfull for the system
