I've tried cleaning out my tmp folder, and that hasn't seemed to have much of an effect. I've also tried going through the tips for trouble-shooting slow builds, with no luck.\r\n\r\nHere's an example of typical output from my server:\r\n```\r\nfile changed components/trip-details/trip-header/template.hbs\r\nfile changed styles/trip-details.scss\r\n\r\nBuild successful - 32805ms.\r\n\r\nSlowest Trees                                 | Total               \r\n----------------------------------------------+---------------------\r\nCachingWriter                                 | 31969ms             \r\n\r\nSlowest Trees (cumulative)                    | Total (avg)         \r\n----------------------------------------------+---------------------\r\nCachingWriter (1)                             | 31969ms   \r\n```\r\n\r\nRunning ```DEBUG=broccoli-caching-writer:* ember s``` is very verbose, but most actions take just a few milliseconds with the exception of:\r\n```\r\n  broccoli-caching-writer:CachingWriter rebuilding cache in 31693ms +32s\r\n```\r\n\r\nI'm also getting a \"cache eviction\" notice--not sure if this is normal or not:\r\n```\r\n  broccoli-caching-writer:SassCompiler  cache eviction due to: \r\n     - {file, /home/nicolas/wdi/projects/oto-client/tmp/sass_compiler-input_base_path-SbenAwPs.tmp/0/app/styles/trip-details.scss, app/styles/trip-details.scss, 33204, 2445, 1466560640422} \r\n     - {file, /home/nicolas/wdi/projects/oto-client/tmp/sass_compiler-input_base_path-SbenAwPs.tmp/0/app/styles/trip-details.scss, app/styles/trip-details.scss, 33204, 2421, 1466560624714} +25ms\r\n```\r\n\r\nInterestingly, the problem is mostly on rebuilds--when I first start up the server it typically completes in ~7 sec. Typically the first couple rebuilds are also <10 sec, but then it quickly creeps up over 20 sec.\r\n\r\nHappy to provide additional info. Any help you could provide would be much appreciated.
