The default threshold to trigger background reclaim is fairly low, around 2MB on a 2GB device and 636KB on a 512MB device. This is a thread that tries to free up pages so the next time a real thread allocates it can succeed quickly. To avoid direct reclaim, the kernel has watermarks that trigger kswapd or background reclaim. This can result in extra I/O in any thread, including a UI thread. This in turn often requires disk I/O to flush out a dirty file-backed page or waiting for lowmemorykiller to kill a process. This requires the kernel to block the allocation while it frees up a page.
Kernel configuration Tuning kernel/ActivityManager to reduce direct reclaim Direct reclaim happens when a process or the kernel tries to allocate a page of memory (either directly or due to faulting in a new page) and the kernel has used all available free memory.
Low-memory devices should not pre-install any live wallpapers. PRODUCT_PROPERTY_OVERRIDES += ro.config.low_ram=true Launcher Configs Ensure the default wallpaper setup on launcher is not using live-wallpaper. It can be enabled by the following system property in the device makefile. For 512MB devices, this API is expected to return true. Build-time configuration Enable Low Ram Device flag We are introducing a new API called ActivityManager.isLowRamDevice() for applications to determine if they should turn off specific memory-intensive features that work poorly on low-memory devices. Memory tracking New memtrack HAL to track graphics memory allocations, additional information in dumpsys meminfo, clarified summaries in meminfo (for example reported free RAM includes RAM of cached processes, so that OEMs don't try to optimize the wrong thing). API Added a new ActivityManager.isLowRamDevice() to allow applications to detect when running on low memory devices and choose to disable large-RAM features. Procstats Added a new Developer Option to show memory state and application memory usage ranked by how often they run and amount of memory consumed.
Then run the test for each PC after you move the base station and PCs, change the positioning of the antennas, and so forth, as outlined in.
