The major bottleneck in pkg-stats is the time spent waiting for answers from remote servers. Two functions involve such communication with remote servers: - 'check_package_urls' which checks that each package upstream website is up, it is efficient due to the use of process-pools thanks to Matt Weber. - 'check_package_latest_version' which fetches the latest package version from release-monitoring, it uses a http-pool but runs sequentially. This patch extends the use of process-pools to 'check_latest_version'. Due to some limitations of multiprocess callbacks, this patch loses the overall progress of packages in favour of just the current package name. Runtimes for this function are ~3m vs ~25m for the linear version. Tested on an i7 7500U (2/4 cores/threads @3.5GHz) with 15ms ping. Note: There have already been work trying to parallelize this function using threads but there were a failure on some configurations [1]. This implementation rely on a dedicated module already in use on this script, so it's unlikely to see failure with this version.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
