zsh shell support in AIX: warning

[strus]

Hi,
Just a word for those who want to use the ZSH shell on a Power5 based machine. DO NOT use the time builtin command, but use the /usr/bin/time command or the KSH builtin instead.
The zsh builtin do not support SPLPAR !
sample:
ZSH:
time ./vloop_32 6
./vloop_32 6 1.79s user 0.00s system 102% cpu 1.752 total

!! 102% whaow !!!

/usr/bin/time ./vloop_32 6

Real 1.95
User 1.88
System 0.00

Otherwise it works!
Note: the zsh shell is not supported by IBM ... so normally you do not use it

It's possible to have 102% or more cpu if you have more than 1 cpu......

Not sure of what you say... and topas confirmed what I think. CPU percent cannot be more than 100% even if you have several CPUs...
I am working on performance tools and I can tell you that it seems to be an effect of the splpar environment.
To be verified by experiment.
