Joerg, Clearly the original poster has no clue what they're talking about. Solaris has always been good under load, something Linux falls with typically. It really wasn't until recentely that Linux could handle 2 CPUs, and the only reason it can *marginally* utilize 2 CPUs is due to Moore's Law, IMO. Running Linux on SMP systems is like running a Yugo on the autobaun. Ok, maybe a Yugo is not a good analogy...maybe it's like a Ford Probe with a bad cylinder.;-) I did run a mysql database on Linux and it stayed up for over 200 days, until the power went out (when I was working at VA Linux Systems). While it was a production system that processed all of VA's orders, it was inside the firewall and I could leave it up without patching/updating the kernel. You can not reliably go that long without updating the kernel because of security fixes on Linux, IMO. I tried running the 2.2 kernel on an SMP system at the time and the system trap'd on me after a half day. I guess the 2.4 kernel might handle SMP, or possibly the 2.6 kernel, but I don't want to find out and why should I when Solaris handles it fine? We haven't even brought up the great tools yet...have you ever tried to debug with gdb? I haven't tried recentely, but as of a year or two back, it couldn't reliably support re-entrancy into a shared library. Although to give it credit you could enter the library *ONCE*, that's a lot of fun. I did like gdbserver, it let's you debug across the network, so when your host dies at least your development machine doesn't!;-) -- Alan DuBoff - Sun Microsystems Solaris x86 Engineering _______________________________________________ opensolaris-discuss mailing list [email protected]
