Description Shane Wang 2011-11-02 20:33:58 UTC

Webmin package building is so slow. So is rebuilding. A question, can the task to find dependency be multi-threading? Nice to have in the future.

I believe this is actually caused by the single-threaded walk over the files and calling rpmdeps.

This is not a BitBake bug, but a core classes bug. package.bbclass to be specific.

This should be faster after http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=12306d01a091899178aca26b629bf14f6161dfb4

Comment 3 Richard Purdie 2013-02-16 23:06:11 UTC

With the recent do_package optimisations, particuarly those preceeding http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=5b7c822609a42e58e96a004071978c9ff196e955 and the ones which enable parallel processing of some operations, I think we can now call this resolved.
