server. \subsection{Benchmark Environment} -These experiments are run on a cluster of homogenous Supermicro SYS-6017R-TDF compute nodes with the following characteristics: +The Memcached experiments are run on a cluster of homogeneous Supermicro SYS-6017R-TDF compute nodes with the following characteristics. +\begin{itemize} +\item The server runs Ubuntu 20.04.3 LTS on top of Linux Kernel 5.11.0-34. +\item Each node has 2 Intel(R) Xeon(R) CPU E5-2620 v2 running at 2.10GHz. +\item These CPUs have 6 cores per CPUs and 2 \glspl{hthrd} per core, for a total of 24 \glspl{hthrd}. -The cpus each have 384 KB, 3 MB and 30 MB of L1, L2 and L3 caches respectively. +\item +The CPUs each have 384 KB, 3 MB and 30 MB of L1, L2 and L3 caches respectively. +\item Each node is connected to the

connection is served by a single \at in a strict 1-to-1 pairing. -This models adds flexibility to the implementation, as the serving logic can now block on user-level primitives without affecting other connections. - -Memcached is not built according to a thread-per-connection model, but there exists a port of it that is, which was built for libfibre in \cite{DBLP:journals/pomacs/KarstenB20}. -Therefore this version can both be compared to the original version and to a port to the \CFA runtime. - -As such, this memcached experiment compares 3 different varitions of memcached: -\begin{itemize} - \item \emph{vanilla}: the official release of memcached, version~1.6.9. - \item \emph{fibre}: a modification of vanilla which uses the thread per connection model on top of the libfibre runtime~\cite{DBLP:journals/pomacs/KarstenB20}. +\item +Network routing is performed by a Mellanox SX1012 10/40 Gigabit Ethernet switch. +\end{itemize} + +\subsection{Memcached threading} +Memcached can be built to use multiple threads in addition to its @libevent@ subsystem to handle requests. +When enabled, the threading implementation operates as follows~\cite{https://docs.oracle.com/cd/E17952_01/mysql-5.6-en/ha-memcached-using-threads.html}: +\begin{itemize} +\item +Threading is handled by wrapping functions within the code to provide basic protection from updating the same global structures at the same time. +\item +Each thread uses its own instance of the @libevent@ to help improve performance. +\item +TCP/IP connections are handled with a single thread listening on the TCP/IP socket. +Each connection is then distributed to one of the active threads on a simple round-robin basis. +Each connection then operates solely within this thread while the connection remains open. +\item +For UDP connections, all the threads listen to a single UDP socket for incoming requests. +Threads that are not currently dealing with another request ignore the incoming packet. +One of the remaining, nonbusy, threads reads the request and sends the response. +This implementation can lead to increased CPU load as threads wake from sleep to potentially process the request. +\end{itemize} +Here, Memcached is based on an event-based webserver architecture~\cite{Pai99Flash}, using \gls{kthrd}ing to run multiple (largely) independent event engines, and if needed, spinning up additional kernel threads to handle blocking I/O. +Alternative webserver architecture are: +\begin{itemize} +\item +pipeline~\cite{Welsh01}, where the event engine is subdivided into multiple stages and the stages are connected with asynchronous buffers, where the final stage has multiple threads to handle blocking I/O. +\item +thread-per-connection~\cite{apache,Behren03}, where each incoming connection is served by a single \at in a strict 1-to-1 pairing, using the thread stack to hold the event state and folding the event engine implicitly into the threading runtime with its nonblocking I/O mechanism. +\end{itemize} +Both pipelining and thread-per-connection add flexibility to the implementation, as the serving logic can now block without halting the event engine~\cite{Harji12}. + +However, \gls{kthrd}ing in Memcached is not amenable to this work, which is based on \gls{uthrding}. +While it is feasible to layer one user thread per kernel thread, it is not meaningful as it fails to exercise the user runtime; +it simply adds extra scheduling overhead over the kernel threading. +Hence, there is no direct way to compare Memcached using a kernel-level runtime with a user-level runtime. + +Fortunately, there exists a recent port of Memcached to \gls{uthrding} based on the libfibre~\cite{DBLP:journals/pomacs/KarstenB20} \gls{uthrding} library. +This port did all of the heavy-lifting, making it straightforward to replace the libfibre user-threading with the \gls{uthrding} in \CFA. +It is now possible to compare the original kernel-threading Memcached with both user-threading runtimes in libfibre and \CFA. + +As such, this Memcached experiment compares 3 different variations of Memcached: +\begin{itemize} + \item \emph{vanilla}: the official release of Memcached, version~1.6.9. + \item \emph{fibre}: a modification of vanilla using the thread-per-connection model on top of the libfibre runtime. \item \emph{cfa}: a modification of the fibre webserver that replaces the libfibre runtime with \CFA. \end{itemize} \subsection{Throughput} \label{memcd:tput} +This experiment is done by having the clients establish 15,360 total connections, which persist for the duration of the experiment. +The clients then send read and write queries with only 3\% writes (updates), attempting to follow a desired query rate, and the server responds to the desired rate as best as possible. +Figure~\ref{fig:memcd:rate:qps} shows the 3 server versions at different client rates, ``Target \underline{Q}ueries \underline{P}er \underline{S}econd'', and the actual rate, ``Actual QPS'', for all three webservers. + +Like the experimental setup in Chapter~\ref{microbench}, each experiment is run 15 times, and for each client rate, the measured webserver rate is plotted. +The solid line represents the median while the dashed and dotted lines represent the maximum and minimum respectively. +For rates below 500K queries per seconds, all three webservers match the client rate. +Beyond 500K, the webservers cannot match the client rate. +During this interval, vanilla Memcached achieves the highest webserver throughput, with libfibre and \CFA slightly lower but very similar throughput. +Overall the performance of all three webservers is very similar, especially considering that at 500K the servers have reached saturation, which is discussed more in the next section. + \begin{figure} \centering -

-Normally, webservers use @sendfile@\cite{MAN:sendfile} to send files over the socket. -@io_uring@ does not support @sendfile@, it supports @splice@\cite{MAN:splice} instead, which is strictly more powerful. -However, because of how linux implements file \io, see Subsection~\ref{ononblock}, @io_uring@'s implementation must delegate calls to splice to worker threads inside the kernel. -As of Linux 5.13, @io_uring@ caps the numer of these worker threads to @RLIMIT_NPROC@ and therefore, when tens of thousands of splice requests are made, it can create tens of thousands of \glspl{kthrd}. -Such a high number of \glspl{kthrd} is more than Linux can handle in this scenario so performance suffers significantly. -For this reason, the \CFA webserver calls @sendfile@ directly. -This approach works up to a certain point, but once the server approaches saturation, it leads to a new problem. - -When the saturation point of the server is attained, latency will increase and inevitably some client connections will timeout. -As these clients close there connections, the server must close these sockets without delay so the OS can reclaim the resources used by these connections. -Indeed, until they are closed on the server end, the connection will linger in the CLOSE-WAIT tcp state~\cite{rfc:tcp} and the tcp buffers will be preserved. -However, this poses a problem using blocking @sendfile@ calls. -The calls can block if they do not have suffcient memory, which can be caused by having too many connections in the CLOSE-WAIT state. -Since blocking in calls to @sendfile@ blocks the \proc rather than the \at, this prevents other connections from closing their sockets. -This leads to a vicious cycle where timeouts lead to @sendfile@ calls running out of resources, which lead to more timeouts. -
