Description Need Real Name 2001-08-10 17:34:27 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.3-12 i686)

Description of problem:
sar does give wrong results on Alpha, it seem to assume that
HZ is 100 for all architectures (tru for Intel, but Alpha is 1024). I guess
sar uses the C function times().

How reproducible:
Always

Steps to Reproduce:
1. sar -u 1	

Actual Results:  dilbert:~> sar -u 1
Linux 2.4.3-12smp (dilbert)     08/10/2001
 
01:39:13 PM       CPU     %user     %nice   %system     %idle
01:39:14 PM       all      2.00      0.00     18.00    1004.00
Average:          all      2.00      0.00     18.00    1004.00

Expected Results:  Total time being at a total of 100% (maybe 200% for dual
processor, but not 1024%)...
