When I did my cross compiles back in 1999, the hand-me-down laptop outperformed the G4 CPU by enough that I could afford to share over NFS and do unzipping and compiles on the latop :-) That clearly shows the expectation problems we had with Linux performance on the early mainframe CPUs. The balance now is the other way: my current laptop may be 2 times as fast, but the modern mainframe CPU gained a factor 20 since then. I envy my friends with a z196. | Rob ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
