...eavy workloads. With 4.17 the situation improved a lot again: - Pathnames given by a client are devided into dirname and basename. ? The amount of syscalls to validate dirnames is reduced to 2 syscalls ? (openat, close) per component. On modern Linux kernels (>= 5.6) smbd ? makes use of the openat2() syscall with RESOLVE_NO_SYMLINKS, ? in order to just use 2 syscalls (openat2, close) for the whole dirname. - Contended path based operations used to generate a lot of unsolicited ? wakeup events causing thundering herd problems, which lead to masive ? latencies for some clients.

After joining a Samba server to domain using either Winbind or using ADBridge (PBIS), enumeration time of listing files from windows file explorer for that share is roughly (9) seconds for a folder containing 30k files consisting of both large (upto 15GB in size) and small size files (as low as KB's). Intitially, without setting logging to "0" and disabling smb max server protocol in
