ios测试代码
Luakit是跨平台的，代码跟android一样，下面就不列了，只给出Coredata和 Realm ios
循环插入
Coredata 定义orm模型结构并做10000次插入
@interface Student (CoreDataProperties) + (NSFetchRequest<Student *> *)fetchRequest; @property (nullable, nonatomic, copy) NSString *claName; @property (nullable, nonatomic, copy) NSString *name; @property (nonatomic) float score; @property (nullable, nonatomic, copy) NSString *studentId; @property (nullable, nonatomic, copy) NSString *teacherName; @end self.context = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSMainQueueConcurrencyType]; for (int i=0; i<10000; i++) { Student *s = [NSEntityDescription insertNewObjectForEntityForName:@"Student" inManagedObjectContext:self.context]; s.studentId = [NSString stringWithFormat:@"studentId%d",i]; s.name = [NSString stringWithFormat:@"name%d",i]; s.teacherName = [NSString stringWithFormat:@"teacherName%d",i]; s.claName = [NSString stringWithFormat:@"claName%d",i]; s.score = 90; NSError *error = nil; [self.context save:&error]; } |
Realm ios定义orm模型结构并做10000次插入
@interface StudentRLM : RLMObject @property NSString *studentId; @property NSString *name; @property NSString *teacherName; @property NSString *claName; @property float score; @end for (int i=0; i<10000; i++) { [realm beginWriteTransaction]; StudentRLM *s = [[StudentRLM alloc] init]; s.studentId = [NSString stringWithFormat:@"studentId%d",i];; s.name = [NSString stringWithFormat:@"name%d",i]; s.teacherName = [NSString stringWithFormat:@"teacherName%d",i]; s.claName = [NSString stringWithFormat:@"claName%d",i]; s.score = 90; [realm addOrUpdateObject:s]; [realm commitWriteTransaction]; [realm beginWriteTransaction]; } |

[realm beginWriteTransaction]; for (int i=0; i<10000; i++) { StudentRLM *s = [[StudentRLM alloc] init]; s.studentId = [NSString stringWithFormat:@"studentId%d",i];; s.name = [NSString stringWithFormat:@"name%d",i]; s.teacherName = [NSString stringWithFormat:@"teacherName%d",i]; s.claName = [NSString stringWithFormat:@"claName%d",i]; s.score = 90; [realm addOrUpdateObject:s]; } [realm commitWriteTransaction]; [realm beginWriteTransaction]; |
查询
Coredata 做10000次查询。
for (int i=0; i<10000; i++) { NSFetchRequest *request = [NSFetchRequest fetchRequestWithEntityName:@"Student"]; request.predicate = [NSPredicate predicateWithFormat:@"studentId = 'studentId%d'"]; NSArray *objs = [self.context executeFetchRequest:request error:&error]; } Realm ios做10000次查询。 for (int i=0; i<10000; i++) { RLMResults *results = [StudentRLM objectsWhere: [NSString stringWithFormat:@"studentId = 'studentId%d'",i]]; StudentRLM *s = results.firstObject; } |
循环更新
Coredata 做10000次更新。
for (int i=0; i<10000; i++) { NSBatchUpdateRequest *batchUpdateRequest = [[NSBatchUpdateRequest alloc] initWithEntityName:@"Student"]; batchUpdateRequest.predicate = [NSPredicate predicateWithFormat:@"studentId = 'studentId%d'"]; batchUpdateRequest.propertiesToUpdate = @{@"name" : @"name2"}; batchUpdateRequest.resultType = NSUpdatedObjectsCountResultType; NSBatchUpdateResult *batchResult = [self.context executeRequest:batchUpdateRequest error:&error]; NSError *error = nil; [self.context save:&error]; } |
Realm ios做10000次更新。
for (int i=0; i<10000; i++) { [realm beginWriteTransaction]; RLMResults *results = [StudentRLM objectsWhere: [NSString stringWithFormat:@"studentId = 'studentId%d'",i]]; NSLog(@"results %lu",(unsigned long)[results count]); StudentRLM *s = results.firstObject; [s setName:@"name"]; [realm addOrUpdateObject:s]; [realm commitWriteTransaction]; } |

ios 测试结果及分析
下面给出测试结果，表格中所有数据的单位是秒，即做10000次操作需要的秒数。
可以看到，Coredata除了批量插入性能是最好的以外，其他项性能都一般。
Realm ios和Realm android性能非常相似，批量操作性能优异，但是非批量操作性能一般。可以这样总结，如果代码高内聚，可以把数据操作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，当操作数据的代码到处都有，不能使用批量接口时，Realm的性能是不好的。
Luakit没有提供批量接口，但从图中可以看出，Luakit的各项性能指标都是比较好的，而且对代码没有要求，即使操作数据的代码不内聚，也不会对性能有影响。
