[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|FIXED |--- Status|RESOLVED |REOPENED Target Milestone|4.0.0 |--- CC| |[email protected] Developer|--- |Research Difficulty| | --- Comment #3 from [email protected] --- This patch causes a MASSIVE build performance regression on Windows, roughly DOUBLING the total build time in branches/gbuild-reintegration, and increasing the main/sw build time almost 6-fold, from 38 minutes to 218: r1409590 in braches/gbuild, merged in r1735004 in branches/gbuild-reintegration gnumake4: #i117845#: LinkTarget.mk: refactor dep-files: introduce dependency from object dep-file to object. It is sufficient to patch only the CxxObject section in Linktarget.mk to reproduce it. Parallelization has little effect: "make -j4" on a 4 core box is only slightly faster than -j2 (187 minutes vs 218), even though 4 instances of cl.exe are found running on sporadic checks. -- You are receiving this mail because: You are on the CC list for the issue.
