After the pc accesses the samba service and modifies the file slowly, the following solutions are available. 1: [global] socketoptionsIPTOS_LOWDELAYTCP_NODELAYSO_RCVBUF16384SO_SNDBUF163842: in smb. conf? Add the following? A. pc access to modify the samba service file is slow. after you query the file on the Internet, the following solutions are available. 1: [global] socket options = IPTOS_LOWDELAY TCP_NODELAY SO_RCVBUF = 16384 SO_SNDBUF = 16384 2: In smb. conf? Add the following? Sentence can be solved? Qsmb ports = 139 3: modify/opt/etc/samba/smb. conf, add [global] read size = 512 socket options = TCP_NODELAY SO_KEEPALIVE SO_RCVBUF = 512 SO_SNDBUF = 512 IPTOS_LOWDELAY getwd cache = yes follow symlinks = no wide links = no read raw = yes write raw = yes large readwrite = yes getwd cache = yes strict locking = no fake oplocks = yes oplocks = no 4: disable firewall and selinux 5. the vhosts and/etc/sysconfig/network host names must be consistent.
