... Anticipatory scheduler (AS). This scheduler is possibly the mostappropriate for interactive systems. It attempts to anticipate the next I/Orequest based on the heuristic that read I/Os tend to be synchronous andsequential while write I/Os tend to asynchronous and random. This canlead to the I/O system queuing up many write I/Os but only receiving newread I/Os when the previous read completes. As a result, when a readcompletes and the I/O system issues the next I/O, it is a write. To service the write, the disk heads are almost certainly required to move to anotherlocation on the disk, a process that will take 5­8mS (a seek plus the diskrotational delay). Meanwhile the reading process will usually issue anotherread, typically at the next sequential location on the disk. The AS schedulerwill attempt to optimize this situation by delaying the issuing of pendingwrites at the end of a read I/O by approximately one millisecond in the anticipation of another sequential read being issued. If the read isrequested it can be honored without any need for an intermediate diskseek. If a read is not issued, the queued write can be started. The cost of delaying the write is small, while the benefit to the reader will be 10­16mS(eliminating the two seeks and rotational delays caused by an off­trackwrite).Object­Based Reverse Map VMRed Hat Enterprise Linux v.3 included a Reverse Map VM (Virtual Memory)feature, developed by Red Hat, which is used to locate all the process virtualaddresses that map to a given physical address. This is needed whenperforming operations such as swapping. Without a Reverse Map VMcapability, physical to virtual address translation is slow and cumbersome andsignificantly impacts the performance of large or memory constrained systems. The Reverse Map VM capability in Red Hat Enterprise Linux v.3 createdadditional memory management structures to perform the reverse translation.This provided a significant Reverse Mapping performance improvement butimposed an overhead on all systems, even those that were not memoryconstrained (it was high cost, high gain). During 2004 the algorithms used byReverse Map VM  were further enhanced to eliminate the additional structuresand use existing memory object structures (file, process, etc). This resulted in an equivalent performance improvement but at minimal additional overhead(low cost, high gain).  An Overview of the Red Hat Enterprise Linux Version 4 Product Family ... 24SPECompm2001 on IBM eServer p5/520This benchmark result, announced in July 2004, used an IBM eServer p5Model 520 with Red Hat Enterprise Linux v.3. The server was configured witha single, dual­core CPU configured with 32 GB of main memory. The testresult of 5287 peak and 4758 base holds the top place for a dual CPU system,almost double the performance of the next 2 CPU system result. TPC/C on HP Itanium cluster with Oracle 10g RAC In December 2003, Red Hat, Oracle, and HP announced the overallperformance world record result for TPC/C, based on a 16 node HP Integritycluster running Oracle 10G RAC with Red Hat Enterprise Linux v.3 AS. The benchmark used a database of approximately 90 Terabytes, deployed on astorage subsystem that included over 2000 disks. The result wasapproximately 50% faster that the fastest Microsoft Windows results and 98%faster than the fastest Sun Solaris result. The benchmark also produced the lowest $/tpmC cost of the top 10 performance­related results. This resultremained the leader for almost a year before being finally displaced by asystem that was almost three times the size. So, currently the result is the #2record holder.Layered Products for Red Hat Enterprise LinuxWith Red Hat Enterprise Linux established as the leading Linux operatingsystem for the commercial environment, Red Hat is working to extend the benefits of open source software further up the software solution stack to the middle­ware and application layers. Red Hat's strategy is to provide a set of optional layered products that can be used to enhance the standard Red HatEnterprise Linux system. The following products, offered with full maintenanceand support services, are available today:Red Hat Global File SystemRed Hat Global File System (GFS) is an open source, POSIX­compliantcluster filesystem and volume manager that executes on Red Hat EnterpriseLinux servers attached to a storage area network (SAN). It works on all majorserver and storage platforms supported by Red Hat. The leading (and first)cluster file system for Linux, Red Hat GFS has the most complete feature set,widest industry adoption, broadest application support, and best price/performance of any Linux cluster file system today.Red Hat GFS allows multiple Red Hat Enterprise Linux servers tosimultaneously read and write a single shared filesystem on the SAN,achieving high performance and reducing the complexity and overhead of managing redundant data copies. Red Hat GFS has no single point of failure,is incrementally scalable from one to hundreds of Red Hat Enterprise Linuxservers, and works with all standard Linux applications.Red Hat GFS is integrated with Red Hat Enterprise Linux and distributedthrough Red Hat Network.  This simplifies software installation, updates, andmanagement. Applications such as Oracle 9i RAC and workloads in cluster An Overview of the Red Hat Enterprise Linux Version 4 Product Family ... Support for Network Interrupt Mitigation (referred to as NAPI, for New API).This feature combines device interrupt handling and polling to optimize the performance of heavily loaded networks. Rather than allow a networkdevice to trigger an interrupt for every arriving packet, NAPI disablesinterrupts as soon as a packet is delivered. The network handler thenenters a polling mode until all pending network packets are drained from the network device's receive buffers. When the last packet has beenserviced, the routine then re­enables interrupts and exits normally. NAPI ismost valuable for Gigabit Ethernet and other networks with high packetarrival rates.•...
