고속 I/O 핵심
1. 고속 표준 입출력
using var reader = new StreamReader(
Console.OpenStandardInput(),
bufferSize: 65536);
using var writer = new StreamWriter(
Console.OpenStandardOutput(),
bufferSize: 65536);
writer.AutoFlush = false;
// 처리 후 수동 플러시
writer.Flush();
2. 파일 I/O
// 64KB 버퍼로 순차 읽기
using var stream = new FileStream(
path,
FileMode.Open,
FileAccess.Read,
FileShare.Read,
bufferSize: 64 * 1024,
options: FileOptions.SequentialScan);
3. RandomAccess (.NET 6+)
using var handle = File.OpenHandle(path, FileMode.Open, FileAccess.Read);
int bytesRead = await RandomAccess.ReadAsync(handle, buffer, offset);
4. 성능 비교
| 방식 | 상대 성능 |
|---|---|
| Console.ReadLine() | 1x |
| StreamReader (64KB) | 3-5x |
| MemoryMappedFile | 5-10x |
