Faz algum tempo que uso linux. Começei com uma pequena partição e hoje já não tenho mais o velho windows instalado. Há poucos dias me associei no Clube do Hardware notei esta parte do fórum, e fui logo "emulando" vários programas, como o superpi, entre outros. Não fiz feio frente aos records que estão marcados em destaque, mas nem mandei screenshot por que não sabia se iam aceitar a minha emulação.
Depois pensei se o fato de estar emulando os programas iria comprometer o meu desempenho. Não sei dizer o quanto isto afeta (não tenho como colocar os programas no windows para comparar), mas deve fazer diferença. Foi então que tive a ideia de sair a procura de benchmarks para linux e, para minha surpresa, existem MUITOS programas e muitas maneiras de se comparar uma distribuição com outra. Outra coisa que pode ser feita sem maiores problemas é a marcação dos frames por segundos (fps) em jogos e tudo mais, MAS para ficar justo frente a máquinas que rodam windows, precisamos de jogos que sejam nativos ao linux: NWN, Enemy-Territory, Quake, entre outros.
Quanto ao benchmarks específicos de linux, temos:
Comandos prórpios do linux: Alguns comandos podem servir para testar a máquina. Exemplos:
* Ttcp - measures the point-to-point bandwidth over a network connection
* Ping - can measure the latency of a network connection
* Hdparm - "-t" and "-T" options can be used to measure disk-to-memory (disk reads) transfer rates
* Dga - the "-b" option measures CPU/video memory bandwidth
E ainda temos:
* lmbench - a GPL'd suite of atomic benchmarks, no publishing restrictions
* UnixBench - a fundamental high-level Linux benchmark suite, Unixbench integrates CPU and file I/O tests, as well as system behaviour under various user loads
* AIM9 - the AIM Independent Resource Benchmark exercises and times each component of a UNIX computer system, independently. The benchmark uses 58 subtests to generate absolute processing rates, in operations per second, for subsystems, I/O transfers, function calls, and UNIX system calls. GPL'd and can be published under the "non-audited" clause.
* Netperf - a sophisticated network and filesystem benchmark, freely available, publishable?
* SSLperf - open source web benchmark designed to measure performance of SSL operations
* dbench - similar workload to netbench but GPL'd and much easier to config and run (doesn't require clients), suite also includes tbench and smbtorture, no publishing restrictions
* Bonnie - io throughput benchmark, GPL'd with no publishing restrictions
* Bonnie++ an enhanced version of bonnie written in C++, GPL'd with no publishing restrictions
* Iozone is useful for performing a broad filesystem analysis of a vendor's computer platform. The benchmark tests file I/O performance for the following operations: Read, write, re-read, re-write, read backwards, read strided, fread, fwrite, random read, pread ,mmap, aio_read, aio_write. It has recently added tests for NFS, CIFS, and distributed/cluster systems.
* SPEC CPU2000 - benchmark suite designed to evaluate raw cpu and compiler power
* BYTEmark - CPU benchmark suite, reporting CPU/cache/memory, integer and floating-point performance
* Cachebench - measures bandwidth of the memory subsystem (L1, L2 and main memory)
* Stream - measures sustainable memory bandwidth vs. FPU performance
* SPECviewperf - synthetic graphics benchmark
* Xengine - a little X window toy that shows the speed with which a system will redraw a coloured bitmap on screen (a simulation of a four cycle engine), availible from www.tux.org/pub/benchmarks/
* Xbench Xserver benchmark
* XMark93 - Xserver benchmark (part of SPEC, defunct?)
E mais:
* Open Source Database Benchmark - GPL'd benchmark based on the AS3AP database benchmark with no publishing restrictions
* VolanoMark - a Java-based chat room benchmark, freely availible, publishable?
* chat - a GPL'd chat room benchmark written in C, designed to emulate VolanoMark behavior, no publishing restrictions
* Postal SMTP mail delivery test and POP mail reception test
* AIM7 - the AIM Multiuser Benchmark - Suite VII tests and measures the performance of Open System multiuser computers. It comes with preconfigured workload mixes for Multiuser/Shared System, Compute Server, Large Database,and File Server. Publishable under the "non-audited" clause.
* Webstone - web server benchmark, freely availible, publishable?
* MDBNCH - a large FORTRAN 77 application benchmark, accesses a large data set in a very irregular pattern, generates misses in both the L1 and L2 caches
* TPC-A - now defunct Online Transaction Processing (OLTP) database benchmark
* TPC-B - now defunct Online Transaction Processing (OLTP) database benchmark
* TPC-C - current industry standard Online Transaction Processing (OLTP) database benchmark
* TPC-D - now defunct Decision Support System (DSS) database benchmark
* TPC-H - current industry standard ad-hoc DSS database benchmark
* TPC-R - current industry standard Business Reporting database benchmark
* TPC-W - current industry standard E-commerce database benchmark
* SPECapc - graphics application benchmark
* SPEC HPC96 - hpc application benchmark
* SPEC JBB2000 - server-side Java benchmark
* SPEC JVM98 - client-side Java benchmark
* SPEC SFS97 - NFS benchmark
* SPEC WEB99 - Web server benchmark
* SPEC SDM - defunct multi-user system benchmark
* NAS Parallel Benchmark - Computational Fluid Dynamics benchmark, source freely available, publishable?
* ARC2D Benchmark - scientific benchmark, source freely available, publishable?
* PARKBENCH - PARellel Kernels and BENCHmarks
* High Performance Linpack Benchmark
