This is, indeed, a very important issue for libraries. What we have discovered with the DTrace analysis is that library parallelism is pretty bad and building library takes a significant chunk of time. Improving it will definitely help. We dodged this issue a bit by allowing library to build in parallel with uts. But as uts parallelism is not bad in the first place (and we are trying to increase it) there is not too much CPU time left for library build. For uts we are trying to build platforms in parallel and for sparc to build specific sun4u architectures in parallel as well. Here is a list of RFEs: 6592974 Kernel can compile in parallel with libraries 6592975 Sparc platforms can be compiled in parallel 6592976 Intel platforms can be compiled in parallel 6592977 sun4u sub-platforms can be compiled in parallel It may also be possible to compile 32 and 64 bit in parallel on x86, at least do this for major parts. - akolb _______________________________________________ tools-discuss mailing list tools-discuss@opensolaris.org
