-%% ==== Samba File Server Topics / Challenges ====
-%%
-%% # performance: scalable file server
-%% #* scale-up: exhaust powerful boxes
-%% #* scale-out: flexible all-active clusters
-%% #* scale-down: perform well on low-end boxes
-%% # interop: multi-protocol access (nfs, afp, ...)
-%% # server workloads / SMB features
-%% #* tune for: small \# of connections, threaded applications
-%% #* Hyper-V, ...
-%% #* SMB3 (clustering, RDMA, ...)
-%% # special file systems support (gluster, ceph, gpfs, btrfs, ...)
-%% # cloud / openstack?...
-%% %* (samba $\leftrightarrow$ cifs.ko alternative to nfs?...)
-
-
-%% ==== Samba File Serving Topics ====
-%%
-%% * Performance
-%% * Clustering (CTDB)

-%%%
-%%%
-%%% ==== Performance - low end systems ====
-%%%
-%%%
-%%% <[block]{Reduction of CPU usage for low profile platforms like arm (SMB2)}
-%%% * Samba 4.0:
-%%% ** didn't saturate 1G nic (arm), CPU 100\%
-%%% * reduced memory allocations
-%%% * instrument SMB 2.1 multi-credit / large MTU
-%%% * Samba 4.2:
-%%% ** saturates 1G nic (arm), CPU $<$ 100\%
-%%% * ==> continuing
-%%% [block]>
-%%%
-%%% ==== Performance - DB performance ====
-%%%
-%%% <[block]{TDB}
-%%% * trivial database
-%%% * used for IPC (smbd processes)
-%%% * cluster (CTDB): local copies
-%%% [block]>
-%%%
-%%% <[block]{hot databases}
-%%% * @locking.tdb@ (open files)
-%%% * @brlock.tdb@ (byte range locks)
-%%% * @notify\_index.tdb@ (for change notify)
-%%% [block]>
-%%%
-%%% ==== Performance - DB performance ====
-%%%
-%%% <[block]{problem 1}
-%%% * fcntl byte range locks for record locks
-%%% * contention via single kernel spinlock
-%%% [block]>
-%%%
-%%% <[block]{solution}
-%%% * alternative to fcntl: pthread robust mutexes
-%%% * ==> massive speedup
-%%% * ==> included in TDB 1.3.1, Samba 4.2
-%%% [block]>
-%%%
-%%% ==== Performance - DB performance ====
-%%%
-%%% <[block]{problem 2}
-%%% * freelist:
-%%% ** single chain, contended (@locking.tdb@)
-%%% ** gets fragmented (singly linked)
-%%% * especially a problem in ctdb-cluster: vacuuming
-%%% [block]>
-%%%
-%%% <[block]{improvements}
-%%% * make use of small per-record freelists (dead records)
-%%% * add automatic defragmentation upon traversal
-%%% * ==> included in TDB 1.3.1, Samba 4.2
-%%% [block]>
-%%%
-%%% ==== Performance - DB performance ====
-%%% <[block]{problem 3}
-%%% * change notify not scalable
-%%% [block]>
-%%%
-%%% <[block]{first improvement}
-%%% * restructured @notify.tdb@ to
-%%% ** global @notify\_index.tdb@ and
-%%% ** local @notify.tdb@
-%%% ** ==> better but still not good enough for some workloads
-%%% [block]>
-%%%
-%%% <[block]{next steps}
-%%% * replace DB-approach by new scalable, async notify daemon using messaging
-%%% * some false positives do not harm
-%%% * ==> TODO
-%%% [block]>
-%%%
-%%%
-%%% ==== Performance - scaling ====
-%%%
-%%% <[block]{parellelism}
-%%% * samba is multi-process:
-%%% ** smbd child process $\leftrightarrow$ TCP connection
-%%% ** event-loop in one process
-%%% * within a smbd process:
-%%% ** pthread-pool jobs for potentially blocking syscalls
-%%% ** ==> parallelism for reads/writes
-%%% ** default for async I/O since Samba 4.0
-%%% [block]>
-%%%
-%%% ==== Performance - scaling ====
-%%%
-%%% <[block]{messaging}
-%%% * classical messaging:
-%%% ** messages.tdb and signals between processes
-%%% ** does not scale well
-%%% * new massaging in Samba 4.2:
-%%% ** fast and scalable messaging based on unix datagram messages
-%%% ** ==> WIP: integrate with AD/DC messaging
-%%% ** ==> features fd-passing for sockets (SMB3 multi-channel)
-%%% ** ==> TODO: integrate into CTDB inter-node-messaging

-%%** ==> changed client retry behaviour!
