To generate these traces, see the [Malloc Debug documentation](https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README.md), the option [record\_allocs](https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README.md#record_allocs_total_entries). -To run these benchmarks, first copy the trace files to the target and -unzip them using these commands: +To run these benchmarks, first copy the trace files to the target using +these commands: adb shell push system/extras/traces /data/local/tmp - adb shell 'cd /data/local/tmp/traces && for name in *.zip; do unzip $name; done' Since all of the traces come from applications, the `memory_replay` program will always call `mallopt(M_DECAY_TIME, 1)' before running the trace. Run the benchmark thusly: - adb shell memory_replay64 /data/local/tmp/traces/XXX.txt - adb shell memory_replay32 /data/local/tmp/traces/XXX.txt + adb shell memory_replay64 /data/local/tmp/traces/XXX.zip + adb shell memory_replay32 /data/local/tmp/traces/XXX.zip -Where XXX.txt is the name of a trace file. +Where XXX.zip is the name of a zipped trace file. The `memory_replay` +program also can process text files, but all trace files are currently +checked in as zip files. Every 100000 allocation operations, a dump of the RSS and VA space will be performed. At the end, a final RSS and VA space number will be printed. |
