Android Honeycomb和ICS的html5sql.js插入速度非常慢

Question

我正在使用html5sql javascript库（html5sql.js）来加速使用Phonegap在Android上的多个HTML5数据库插入。 Android 2.X似乎非常快（1秒内1000行）但Android 3.X和4.X（几分钟内1000行）速度非常慢。有谁知道解决方案？

我的代码片段：

sqlStatements = 'INSERT INTO table ("id","data") VALUES("' + id + '", "' + data + '"); INSERT INTO ... ' // 1 thousand inserts 
html5sql.openDatabase(
         "dbase",
         "dbase",
         3*1024*1024);

html5sql.process(
            //This is the text data from the SQL file you retrieved
            sqlStatements,
            function(){
                // After all statements are processed this function will be called.
                console.log("success ");
            },
            function(error){
                // Handle any errors here
                console.log("error " + error);
            }
        );

Answer 1

尝试运行“PRAGMA synchronous = OFF; PRAGMA count_changes = OFF; PRAGMA journal_mode = MEMORY; PRAGMA temp_store = MEMORY;”在第一次sql查询之前
