I measure the overall memory consumption during compilation using linux control group feature. https://github.com/gsauthof/cgmemtime Results are v1.7.x Child user: 7658.352 s Child sys : 263.657 s Child wall: 199.661 s Child high-water RSS : 1952024 KiB Recursive and acc. high-water RSS+CACHE : 54680084 KiB v1.6.x Child user: 5758.186 s Child sys : 222.487 s Child wall: 131.241 s Child high-water RSS : 2040712 KiB Recursive and acc. high-water RSS+CACHE : 45344596 KiB v1.5.x Child user: 3800.705 s Child sys : 143.353 s Child wall: 112.121 s Child high-water RSS : 1604820 KiB Recursive and acc. high-water RSS+CACHE : 37374300 KiB `ccache` is always cleaned between compilations. Results obtained with: ``` CC=gcc-7 CXX=g++-7 cmake -GNinja -DUSE_CUDA=0 .. cgmemtime ninja ``` This is preliminary in that it measures parallel compilation, thus memory usage is very high. Overall there's a 44% increase from 1.5 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
