Android下Protobuff框架性能測試結果

　　android 下Protobuff常用的框架有三個: protobuff自身,  square出的wire , protostuff

　　由于protobuff會為每個屬性生成大量不常用的方法,當程序比較復雜時容易超過android的60K個方法的上限, 所以本次測試未包括protobuff

　　測試邏輯是循環100次序列化100個元素的數組,并反序列化,求平均值,代碼如下:

　　wire的測試代碼:

public void onClickButton(View view){ if (TestTask.isCancel){ TestTask.isCancel = false; TestTask.sumDeserializeTime = 0; TestTask.sumTime = 0; TestTask.runCount = 0; TextView text1 = (TextView) findViewById(R.id.textView2); text1.setText(""); new TestTask( (TextView) findViewById(R.id.textView2) , (TextView) findViewById(R.id.button1)).execute(); ((TextView)view).setText("測試中,點擊中斷"); }else{ ((TextView)view).setText("正在中斷..."); TestTask.isCancel = true; } } static class TestTask extends AsyncTask<Void,Void,Long>{ long serializeTime=0; long deserializeTime=0; static long sumTime=0; static long sumDeserializeTime=0; static int runCount=0; static boolean isCancel=true; TextView text1; TextView btn; public TestTask(TextView text1,TextView btn) { this.text1 = text1; this.btn = btn; } @Override protected Long doInBackground(Void... params) { long startTime = System.currentTimeMillis(); for (int i = 0; i < 100; i++) { List<ListItem> itemList = new ArrayList<ListItem>(); ListItem.Builder itemBuilder = new ListItem.Builder(); ListItem item; for (int j = 0; j < 100; j++) { item = itemBuilder.title("test Title"+i+":"+j) .remark("test Remark"+i+":"+j) .coverUrl("http://pic.ozreader.com/abc.pic") .uri("PKB:TESTURI") .build(); itemList.add(item); } ScrollList.Builder listBuilder= new ScrollList.Builder(); ScrollList list = listBuilder.haveMore(false).tags(itemList).build(); byte[] dataBuffer = list.toByteArray(); serializeTime = System.currentTimeMillis()-startTime; Wire wire = new Wire(); try { ScrollList resultList = wire.parseFrom(dataBuffer, ScrollList.class); if (resultList == null){ Log.e("TEST", "resultList is null"); break; }else if (resultList.tags == null){ Log.e("TEST", "resultList.tags is null"); break; }else if (resultList.tags.size() <= 0){ Log.e("TEST", "resultList.tags is empty"); break; }else if (resultList.tags.size() != 100){ Log.e("TEST", "resultList.tags is wrong"); break; }else if (!resultList.tags.get(0).uri.equals("PKB:TESTURI")){ Log.e("TEST", "resultList.tags content is wrong"); break; } deserializeTime = System.currentTimeMillis()-startTime-serializeTime; } catch (IOException e) { e.printStackTrace(); } } return System.currentTimeMillis() - startTime; } @Override protected void onPostExecute(Long result) { sumTime += result; sumDeserializeTime += deserializeTime; runCount ++; text1.append("result:"+result+", serializeTime:"+serializeTime+", deserializeTime:"+deserializeTime+", runCount:"+runCount+", avg:"+sumTime/runCount+", avg deserializeTime:"+sumDeserializeTime/runCount+"\n"); if (isCancel){ text1.append("測試中斷."); btn.setText("開始測試"); }else if (runCount < 100){ new TestTask(text1,btn).execute(); }else{ isCancel = true; text1.append("測試完成."); btn.setText("開始測試"); } } }

protobuff的測試代碼:

public void onClickButton(View view){ if (TestTask.isCancel){ TestTask.isCancel = false; TestTask.sumDeserializeTime = 0; TestTask.sumTime = 0; TestTask.runCount = 0; TextView text1 = (TextView) findViewById(R.id.textView2); text1.setText(""); new TestTask( (TextView) findViewById(R.id.textView2) , (TextView) findViewById(R.id.button1)).execute(); ((TextView)view).setText("測試中,點擊中斷"); }else{ ((TextView)view).setText("正在中斷..."); TestTask.isCancel = true; } } static class TestTask extends AsyncTask<Void,Void,Long>{ long serializeTime=0; long deserializeTime=0; static long sumTime=0; static long sumDeserializeTime=0; static int runCount=0; static boolean isCancel=true; TextView text1; TextView btn; public TestTask(TextView text1,TextView btn) { this.text1 = text1; this.btn = btn; } @Override protected Long doInBackground(Void... params) { long startTime = System.currentTimeMillis(); for (int i = 0; i < 100; i++) { List<ListItem> itemList = new ArrayList<ListItem>(); ScrollList list = new ScrollList(); list.setHaveMore(false); list.setTagsList(itemList); ListItem item; for (int j = 0; j < 100; j++) { item = new ListItem(); item.setTitle("test Title"+i+":"+j); item.setRemark("test Remark"+i+":"+j); item.setCoverUrl("http://pic.ozreader.com/abc.pic"); item.setUri("PKB:TESTURI"); itemList.add(item); } LinkedBuffer buffer = LinkedBuffer.allocate(1024); byte[] dataBuffer = ProtobufIOUtil.toByteArray(list, ScrollList.getSchema(), buffer); serializeTime = System.currentTimeMillis()-startTime; ScrollList resultList = new ScrollList(); ProtobufIOUtil.mergeFrom(dataBuffer, resultList, ScrollList.getSchema()); if (resultList.getTagsList() == null){ Log.e("TEST", "resultList.tags is null"); break; }else if (resultList.getTagsList().size() <= 0){ Log.e("TEST", "resultList.tags is empty"); break; }else if (resultList.getTagsList().size() != 100){ Log.e("TEST", "resultList.tags is wrong"); break; }else if (!resultList.getTagsList().get(0).getUri().equals("PKB:TESTURI")){ Log.e("TEST", "resultList.tags content is wrong"); break; } deserializeTime = System.currentTimeMillis()-startTime-serializeTime; } return System.currentTimeMillis() - startTime; } @Override protected void onPostExecute(Long result) { sumTime += result; sumDeserializeTime += deserializeTime; runCount ++; text1.append("result:"+result+", serializeTime:"+serializeTime+", deserializeTime:"+deserializeTime+", runCount:"+runCount+", avg:"+sumTime/runCount+", avg deserializeTime:"+sumDeserializeTime/runCount+"\n"); if (isCancel){ text1.append("測試中斷."); btn.setText("開始測試"); }else if (runCount < 100){ new TestTask(text1,btn).execute(); }else{ isCancel = true; text1.append("測試完成."); btn.setText("開始測試"); } } }

　　測試結果為(單位豪秒):

　　手機環境:魅族MX2

　　1) wire 1.5.1 ,網址 https://github.com/square/wire

　　avg: 1860~1907 , 最小值約為1500左右,極少出現, 全過程隨機分布

　　avg deserializeTime: 9~10, 最小值約為5,極少出現,全過程隨機分布

　　2) protostuff 1.0.8 ,網址 https://code.google.com/p/protostuff/

　　avg: 1100~1150,非常穩定 , 最小值約為450左右,主要集中在前幾次循環,循環10次后就穩定在11XX左右,偶有600~800的情況,多次重復測試情況基本一致,觀察自動GC并無內存泄漏的問題, 暫時不確定速度變化的原因.

　　avg deserializeTime: 6, 最小值約為3,極少出現,主要集中在剛開始,絕大多數為5,偶有達到16的情況.

　　分析: wire的性能明顯比不上protostuff, 速度也不太穩定,起落較大.  考慮到protostuff的開發模式是普通的pojo方式,比較方便,不像protobuff和wire的builder方式,超麻煩. 所以最終推薦不是邏輯超復雜的企業app都使用protostuff .
