Juan Miranda,
It seems quite strange,there is little wait event in the statspack
report, and you execution path should be the same on both platform, right? And is the
data volumn the same in both platform?And does the time spent on fetch the result from
server to your client different?Is the speed of your pc to linux and hp the same?
