On the Solaris 8 I tested (1GHz; the identical test outputs):

| 1. Syntax of the shell scripts (tools.at:47): ok        (0m8.980s 0m44.410s)
| 2. Syntax of the Perl scripts (tools.at:70): ok (0m0.920s 0m0.190s)
| 3. autom4te cache (tools.at:88): ok     (0m0.840s 0m0.620s)

Now with current CVS (but the system is loaded ATM):
| $ \time /bin/sh -n testsuite
| 
|  real     5:41.1
|  user       10.0
|  sys        50.5

(No further analysis done yet.)
