Perhaps this exists, and I've just missed finding it. What I would propose is something akin to the gentoo stats page, only for emerge times of various packages on various machines. A script would be run by the user that would process /var/log/emerge.log, /proc/meminfo and /proc/cpuinfo. The data would be uploaded to a server, would include the package name, the time it took to emerge, the amount of memory on the machine, cpu speed, and cpu model. A prospective user could check to see how long emerging KDE might take on this machine (or at least a specific KDE package, such as kde-base). Perhaps some generics could be handled such that when a user processes the log for "emerge kde", a min, max, and average number of packages, and the time it took could be generated. About the only change I see necessary to implement this would be to added to the emerge log what 'nice' level the emerge is running at. This would obviously skew results one way or the other, if it's been nice'd up or down. Reproducible: Always Steps to Reproduce:
