For good measure, here's another `time cat /etc/sendmail.cf': == 2.0 == 0.72 real 0.01 user 0.31 sys == 1.x == 0.17 real 0.01 user 0.10 sys Here's `time cat /usr/share/calendar/*': == 2.0 == 2.44 real 0.00 user 0.92 sys == 1.x == 2.06 real 0.00 user 0.24 sys Here's `time cat web2'. (`web2' being 1.x's /usr/share/dict/web2.) My desktop is a Linux box running XFree 2.0 or 2.1. I have 5 windows on my desktop now. This one was done "hands off", only the particular telnet window doing the `cat' had any activity. == 2.0 == 150.19 real 0.00 user 46.45 sys == 1.x == 0.0u 11.2s 2:26.40 7.6% 36+148k 297+0io 0pf+0w Here's `time cat /etc/sendmail.cf > /dev/null': == 2.0 == 0.09 real 0.00 user 0.06 sys == 1.x == 0.03 real 0.00 user 0.03 sys Here's `time cat /usr/share/calendar/* > /dev/null': == 2.0 == 0.12 real 0.01 user 0.12 sys == 1.x == 0.05 real 0.01 user 0.03 sys Here's `time cat web2 > /dev/null': == 2.0 == 3.63 real 0.00 user 0.67 sys == 1.x == 0.0u 0.3s 0:00.31 106.4% 44+163k 0+1io 0pf+0w Just for kicks, I did some of the above on the consoles. As noted by J"org, 1.x runs pccons, 2.0 syscons. Here's `time cat /etc/sendmail.cf': == 2.0 == 2.41 real 0.00 user 2.40 sys == 1.x == 2.01 real 0.00 user 1.92 sys Here's `time cat /etc/sendmail.cf > /dev/null': == 2.0 == 0.08 real 0.00 user 0.10 sys == 1.x == 0.03 real 0.00 user 0.03 sys Here's `time cat web2': == 2.0 == 751.63 real 0.00 user 739.80 sys == 1.x == 650.10 real 0.00 user 649.73 sys Here's `time cat web2 > /dev/null': == 2.0 == 3.66 real 0.00 user 0.73 sys == 1.x == 0.34 real 0.00 user 0.33 sys I hope these figures tell somebody something. If anyone can suggest anything to try next, I'll be glad to do it. Cheers. - PS -- Ng Pheng Siong * lsys@np.ac.sg * ngps@np.ac.sg Computer Centre, Ngee Ann Polytechnic, Singapore
