[parisc-linux] another profile (2.5.67-pa3)

[b.gunreben@web.de]

Hi,      =20
      =20
I just did a profile of a gcc33 compiled 2.5.67-pa3. I sometimes had the i=
mpression,     =20
that especially shell scripts run very slow on parisc. What I did, was bui=
lding a howto     =20
package, where several keywords are searched with grep -v in all howtos. =20
     =20
user  :       0:01:11.25   0.4%  page in :        0     =20
nice  :       1:24:24.96  25.0%  page out:        0     =20
system:       4:02:17.73  71.8%  swap in :        0     =20
idle  :       0:09:00.58   2.7%  swap out:        0     =20
uptime:       5:37:28.50         context :  3593391     =20
     =20
procinfo also shows another problem with page counts, but more interesting=
 is, that the     =20
system (from a freshly booted system) needed lots of system time to build =
that package,     =20
and not so much nice time. The total build time was   =20
   =20
built howto in 17650 s   =20
compared to   =20
built howto in 23414 s  =20
