Anyway there's a thing that let me confused. It seems to me that performance of UML Guest machine is sensibly worst then UML Host ... even if there is only one UML guest and no other processes sucking resources. My Setup is: Athlon 1000 512 RAM 1 GB tmpfs /tmp 30GB 4200 eide The guest is started with 256MB of RAM I can post /proc/cpuinfo: Host: model name : AMD Athlon(tm) Processor cpu MHz : 1000.502 cache size : 64 KB bogomips : 1970.17 Guest: processor : 0 vendor_id : User Mode Linux model name : UML mode : skas host : Linux Pancho 2.6.8.1-cko8 #2 Mon Oct 11 17:03:08 CEST 2004 i686 bogomips : 1081.34 Here are results of Kernel Time compiling with the same .config: Host: real 15m27.226s user 13m49.185s sys 1m12.144s Guest: real 29m27.603s user 21m16.970s sys 7m59.080s The Bogomips of the Guest are the half of the Host and compiling time is almost the double. I want to know if this is "Normal" or i have to look for some errors in my configuration.
