服务器压力测试

2010/6/8镜像同步12 回复

客户端和服务器都用的Winsock，版本1.1 客户端频繁向服务器发送消息，服务器接到消息后不做任何处理然后向客户端发送一条消息，客户端计数器加1，每1000条打印一条记录。这样没6w条记录的时候会卡，连接错误，请问是什么原因，有人遇到过吗？客户端 #include "Winsock.h" #include "stdio.h" int main() { WORD wVersionRequested; WSAData wsaData; int err; wVersionRequested = MAKEWORD(1, 1); err = WSAStartup(wVersionRequested, &wsaData); if (err != 0) return 0; if (LOBYTE(wsaData.wVersion) != 1 || HIBYTE(wsaData.wVersion) != 1) { WSACleanup(); return 0; } SOCKADDR_IN addrSrv; addrSrv.sin_addr.S_un.S_addr = inet_addr("192.168.0.104"); addrSrv.sin_family = AF_INET; addrSrv.sin_port = htons(4000); char szRecBuf[100]; int i=0; while (1) { SOCKET sockClient = socket(AF_INET, SOCK_STREAM, 0); if (connect(sockClient, (SOCKADDR*)&addrSrv, sizeof(SOCKADDR))<0) { printf("Connect error!\n"); Sleep(100); continue; } if(send(sockClient, "this is client.", strlen("this is client.")+1, 0)<0) { printf("Send error!\n"); Sleep(100); continue; } memset(szRecBuf,100,'0'); if (recv(sockClient, szRecBuf, sizeof(szRecBuf), 0)<0) { printf("Receive error!\n"); Sleep(100); continue; } closesocket(sockClient); i++; printf("\r%d",i); if(i%1000==0) printf("\n"); } WSACleanup(); return 0; } 服务端 #include <Winsock.h> #include <stdio.h> int main() { WORD wVersionRequested; WSADATA wsaData; int err; wVersionRequested = MAKEWORD(1, 1); err = WSAStartup(wVersionRequested, &wsaData); if (err != 0) return 0; if (LOBYTE(wsaData.wVersion) != 1 || HIBYTE(wsaData.wVersion) != 1) { WSACleanup(); return 0; } SOCKET sockSrv = socket(AF_INET, SOCK_STREAM, 0); SOCKADDR_IN addrSrv; addrSrv.sin_addr.S_un.S_addr = htonl(INADDR_ANY); addrSrv.sin_family = AF_INET; addrSrv.sin_port = htons(4000); bind(sockSrv, (sockaddr*)&addrSrv, sizeof(SOCKADDR)); listen(sockSrv, 5); SOCKADDR_IN addrClient; int len = sizeof(SOCKADDR); while (1) { printf("begin accept\n"); SOCKET sockConn = accept(sockSrv, (SOCKADDR*)&addrClient, &len); printf("accepted\n"); char szSendBuf[100], szRecBuf[100]; recv(sockConn, szRecBuf, sizeof(szRecBuf), 0); printf("%s\n", szRecBuf); memset(szRecBuf,100,'0'); sprintf(szSendBuf, "Welcome %s!", inet_ntoa(addrClient.sin_addr)); send(sockConn, szSendBuf, strlen(szSendBuf)+1, 0); closesocket(sockConn); printf("close accept socket\n"); } closesocket(sockSrv); return 0; }
