移动端orm框架性能测评
移动端orm框架性能测评
flutter_orm_plugin 发布以来，很多团队试用了，我发现你们对这类数据库相关的库，第一反应就是性能如何，以前确实没作太多行业对比，最近以为仍是有必要作一下性能测试，给你们一个交代的。java
在ios端，业界比较经常使用的orm框架应该是苹果官方推出的coredata，还有就是realm了。在android端orm框架我挑了三个比较经常使用的，greendao，realm和activeandroid。我会用flutter_orm_plugin跟上面提到的ios和android端orm框架作对比。 下面我会分别给出测试用例，测试代码，还有最终数据比较的结果。android
测试用例
测试用例我列了如下这些ios
- 10000次插入数据
- 使用批量接口10000次插入数据
- 10000次读取数据
- 10000次修改数据
- 使用批量接口10000次修改数据
- 10000次删除数据
- 使用批量接口10000次删除数据
为何会有普通插入数据和使用批量接口插入数据的区别，大部分orm框架都会对批量操做有必定的优化，因此须要对批量操做进行测试，可是在平时使用，不必定都能用上批量接口（例如屡次数据操做不在同一代码块，或者在不一样的模块中都要操做数据），因此咱们会分别对普通操做和批量操做进行测试。git
android 测试代码
首先咱们给出flutter_orm_plugin 的测试代码，因为不想由于flutter和原生channel通信产生偏差，咱们直接用Luakit来写lua代码作测试（greendao、realm、activeandroid、coredata都不涉及flutter和原生channel通信），flutter_orm_plugin其实底层就是luakit的orm框架，这个不影响测试准确性。github
循环插入
Luakit定义orm模型结构并作10000次插入，下面的代码是ios和android通用的。数据库
local Student = {
__dbname__ = "test.db",
__tablename__ = "Student",
studentId = {"TextField",{primary_key = true}},
name = {"TextField",{}},
claName = {"TextField",{}},
teacherName = {"TextField",{}},
score = {"RealField",{}},
}
local params = {
name = "Student",
args = Student,
}
Table.addTableInfo(params,function ()
local studentTable = Table("Student”) for i=1,10000 do local s = { studentId = "studentId"..i, name = "name"..i, claName = "claName"..i, teacherName = "teacherName"..i, score = 90, } studentTable(s):save() end end) 复制代码

s.teacherName = "teacherName"+i;
s.claName = "claName"+i;
s.score = 90;
s.save();

android 测试结果及分析
下面给出测试结果，表格中全部数据的单位是秒，即作10000次操做须要的秒数。
-
能够看到，active android各项性能都通常。
-
在使用批量接口的状况下GreenDao和Realm的性能比较好。
-
在使用批量接口的状况下Realm的性能尤为好，批量插入、查询、批量更改、批量删除都是Realm的性能最好，可是Realm的非批量接口性能较差，全部能够这样总结，若是代码高内聚，能够把数据操做代码入口都统一使用，Realm性能是最好的，但这对代码质量、模块设计有要求，当操做数据的代码处处都有，不能使用批量接口时，Realm的性能是很差的。
-
Luakit没有提供批量接口，但从图中能够看出，Luakit的各项性能指标都是比较好的，并且对代码没有要求，即便操做数据的代码不内聚，也不会对性能有影响。
