Common Log File System in windows 2008 性能测试

CLFS 是windows 服务器系统内置支持的日志系统

可以直接使用System.IO.Logging 命名空间下面的相关类来操作

写入速度测试

环境:windows2008R2 sp1  (不要在xp上测试..这东西不支持的)

没有raid

8g 内存

CPU: E5440

写入1百万条日志

每条512KB

预计日志大小至少512M

最终耗时22秒...

平均每秒4万多条

测试代码很烂....如下所示

string fullPath = @"c:\log\1.log";
            int extentSize = 20 * 1024 * 1024;
            int logCount = 1 * 1000 * 100;
            LogStore _store = new LogStore(fullPath, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite);

            LogRecordSequence _sequence = new LogRecordSequence(_store, 1 * 1024 * 1024, 1024);

            _sequence.RetryAppend = true;

            if (_store.Extents.Count == 0)
            {
                _store.Extents.Add(fullPath, extentSize);
            }
            string logContent = @"
