...ond), dd''s reported speed, etc. both dom0 and domU are allocated 512MB of RAM, so reading the 1GB file should not benefit from caching. dd bs=1000000 count=1000 if=/dev/zero of=junk (sync, wait, etc) dd bs=1000000 count=1000 of=/dev/zero if=junk In dom0, I achieve 45MB/s write speed and 63MB/s read speed reasonably consistently. I guess this should be reasonable speeds for a partition on LVM on linux software raid 0 on a pair of SATA drives near the front of the disk. This speed was observed using dd output as well as dom0 vmstat. In domU, I achieve also about 45MB/s write speed but...

I'm using the Yocto Project to build an embedded distro, to which I'm adding Samba 3.6 from OpenEmbedded. Doing so increases my root file system from about 63MB to 175MB. I seem to be building a large Samba server with a small ancillary operating system tacked onto it. I listed the files in my file system image, and see that lots of the commands are quite large. I understand that Samba 4 is better behaved in this way, but writing my own bitbake recipe to...

...he use of sparcv9 on Solaris and 32 by gcc on `x86_64' Linux. If you have two or more such builds you can install them over each other (and one build can be done without `r_arch'). The space savings can be considerable: on `x86_64' Linux a basic install (without debugging symbols) took 63Mb, and adding a 32-bit build added 6Mb. If you have installed multiple build you can select which build to run by R --arch=name and running `R' will run the last build that was installed. R CMD INSTALL will detect if more that one build is installed and try to install packages with the app...

Hello, I have an project running on a dedicated server: Debian, P4 CPU 3.00GHz, 1GB RAM, ruby 1.8.4 (2005-12-24) [x86_64-linux], rails (1.0.0), activerecord (1.13.2) lighttpd-1.4.10 + fastcgi + mysql 5.0 7 dispatchers. The project is a game, so a typical user would visit 100+ pages. When the server is busiest, it gets 35-40k requests/hour. For some misterious reason after a number of hours the
