-# Memory tests
-
-## Usage
-
-These scripts are made to parse TCMalloc output in order to extract certain
-info from them.
-
-In particular, these scripts rely on the error logging system for ChromeOS in
-order to extract information. In order to use a script (e.g. `total_mem.py`),
-you just have the command:
-
-```
-./total_mem.py FILENAME
-```
-
-where `FILENAME` is the name of the log file to be parsed.
-
-## Codebase Changes
-
-There are two ideas that motivate these changes:
-
-1. Turn on TCMalloc sampling.
-2. Use perf to collect the sample information.
-
-
-The following files have to be changed:
-
-in `chrome/browser/metrics/perf_provider_chrome_os`, add:
-
-```
-#include "third_party/tcmalloc/chromium/src/gperftools/malloc_extension.h"
-```
-
-Change the perf profiling interval to something small (60*1000 milliseconds).
-
-Inside DoPeriodicCollection, insert the following code:
-
-```
-std::string output;
-char* chr_arr = new char[9999];
-MallocExtension::instance() ->GetHeapSample(&output);
-MallocExtension::instance() ->GetStats(chr_arr, 9999);
-LOG(ERROR) << "Output Heap Data: ";
-LOG(ERROR) << output;
-LOG(ERROR) << "Output Heap Stats: ";
-output = "";
-for (unsigned int i = 0; i < strlen(chr_arr); i++) {
-    output += chr_arr[i];
-}
-LOG(ERROR) << output;
-delete[] chr_arr;
-```
