안녕하세요.
스마트 클라이언트에 관해 쓰신 글을 읽고 회사 프로젝트에 적용해 개발중에 있습니다.
FarPoint사의 윈폼용 스프레드 컨트롤을 새로운 윈폼 컨트롤에 얹어 ASP.NET에서 사용중인데,
실제 웹서버에 사이트를 올리고 사용해보니,
셀을 이동할때마다 웹서버와 패킷을 송수신하여 성능이 급격히 떨어지는 문제가 발생했습니다.
네트워크 모니터로 모니터링해보니 셀을 이동할때 계속해서 웹서버와 패킷을 주고 받고 있었습니다.
짧은 소견으로는 스마트클라이언트와 웹서버간에 연결을 유지하기 위한 패킷으로도 생각되지만 잘 모르겠습니다.
웹페이지가 정상적으로 출력된 상태에서 오프라인을 시키면 당연히 웹서버와 패킷송수신이 없으므로
빠른속도록 셀 이동이나 편집이 가능해집니다.
하지만 다시 연결하면 패킷송수신이 시작되면서 속도가 급격히 떨어지구요.
조언 부탁드려요.
네트워크 모니터로 캡춰한 내용의 일부는 다음과 같습니다.
