What are your thoughts on improving the throughput during busy times on Open Build Service (OBS)? [1] Fusion-IO cards listing on ebay ,some models that were listed for less than $3000.
I'll say it once, and I'll say it again: it does not pay off to invest in anything more than SSDs. $ time osc build -bd --clean openSUSE_Factory x86_64 nx-libs.spec [I added an "exit 1" call at the end of %prep] Machine 1 (i7-2600K, 32G RAM, osbuild-packagecache on rotational disk seagate ST3000DM001-9YN166, buildroot on ...): tmpfs: 21 s disk: 55 s Machine 2 (i7-2600K, 32G RAM, osbuild-packagecache on SSD, buildroot on ...): tmpfs: 17 s ssd: 19 s These tests were hot runs, so packagecache was buffered in RAM. As such, extracing the RPMs to populate the buildroot was essentially a huge memcpy from and to RAM. = FusionIO won't help here. -- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-buildservice+owner@opensuse.org
