Tested 1/2x, 1x, 2x, and 4x the current readahead buffer and noop and cfq I/O schedulers for /dev/block/sda, which contains /data. The most consistent performance boost was seen across all UFS vendors and storage sizes using cfq and a readahead buffer of 1024. Note: testing was done on Walleye, not Taimen Bug: 38000161 Test: Compared 1P app launch times using app-launcher for schedulers (noop, cfq) and readahead buffer sizes (128,512,1024,2048) Change-Id: I7551a4110ad025ec7975dd39301f048f0942f585
