Date: Monday, July 14, 2025 PM08:42:05 HKT Test set: performance Kernel: 6.16.0-0.rc6.251.vanilla.fc42.x86_64 Release: Fedora release 42 (Adams) Result: PASS Failed Tests: None Warned Tests: None ============================================================ Starting test ./performance/lmbench3 cd src && make make[1]: Entering directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Entering directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Nothing to be done for 'all'. gmake[2]: Leaving directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Entering directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Nothing to be done for 'opt'. gmake[2]: Leaving directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' make[1]: Leaving directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' cd src && make results make[1]: Entering directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Entering directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Nothing to be done for 'all'. gmake[2]: Leaving directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Entering directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' gmake[2]: Nothing to be done for 'opt'. gmake[2]: Leaving directory '/home/user/Repo/kernel-tests/performance/lmbench3/src' ===================================================================== L M B E N C H C ON F I G U R A T I O N ---------------------------------------- You need to configure some parameters to lmbench. Once you have configured these parameters, you may do multiple runs by saying "make rerun" in the src subdirectory. NOTICE: please do not have any other activity on the system if you can help it. Things like the second hand on your xclock or X perfmeters are not so good when benchmarking. In fact, X is not so good when benchmarking. ===================================================================== Hang on, we are calculating your timing granularity. OK, it looks like you can time stuff down to 1000000 usec resolution. Hang on, we are calculating your timing overhead. OK, it looks like your gettimeofday() costs 0 usecs. Hang on, we are calculating your loop overhead. OK, it looks like your benchmark loop costs 0.00000000 usecs. ===================================================================== If you are running on an MP machine and you want to try running multiple copies of lmbench in parallel, you can specify how many here. Using this option will make the benchmark run 100x slower (sorry). NOTE: WARNING! This feature is experimental and many results are known to be incorrect or random! MULTIPLE COPIES [default 1] Options to control job placement 1) Allow scheduler to place jobs 2) Assign each benchmark process with any attendent child processes to its own processor 3) Assign each benchmark process with any attendent child processes to its own processor, except that it will be as far as possible from other processes 4) Assign each benchmark and attendent processes to their own processors 5) Assign each benchmark and attendent processes to their own processors, except that they will be as far as possible from each other and other processes 6) Custom placement: you assign each benchmark process with attendent child processes to processors 7) Custom placement: you assign each benchmark and attendent processes to processors Note: some benchmarks, such as bw_pipe, create attendent child processes for each benchmark process. For example, bw_pipe needs a second process to send data down the pipe to be read by the benchmark process. If you have three copies of the benchmark process running, then you actually have six processes; three attendent child processes sending data down the pipes and three benchmark processes reading data and doing the measurements. Job placement selection: ===================================================================== Several benchmarks operate on a range of memory. This memory should be sized such that it is at least 4 times as big as the external cache[s] on your system. It should be no more than 80% of your physical memory. The bigger the range, the more accurate the results, but larger sizes take somewhat longer to run the benchmark. MB [default 5551] Checking to see if you have 5551 MB; please wait for a moment... Hang on, we are calculating your cache line size. OK, it looks like your cache line is bytes. ===================================================================== lmbench measures a wide variety of system performance, and the full suite of benchmarks can take a long time on some platforms. Consequently, we offer the capability to run only predefined subsets of benchmarks, one for operating system specific benchmarks and one for hardware specific benchmarks. We also offer the option of running only selected benchmarks which is useful during operating system development. Please remember that if you intend to publish the results you either need to do a full run or one of the predefined OS or hardware subsets. SUBSET (ALL|HARWARE|OS|DEVELOPMENT) [default all] ===================================================================== This benchmark measures, by default, file system latency. That can take a long time on systems with old style file systems (i.e., UFS, FFS, etc.). Linux' ext2fs and Sun's tmpfs are fast enough that this test is not painful. If you are planning on sending in these results, please don't do a fast run. If you want to skip the file system latency tests, answer "yes" below. SLOWFS [default no] ===================================================================== If you are running on an idle network and there are other, identically configured systems, on the same wire (no gateway between you and them), and you have rsh access to them, then you should run the network part of the benchmarks to them. Please specify any such systems as a space separated list such as: ether-host fddi-host hippi-host. REMOTE [default none] ===================================================================== Calculating mhz, please wait for a moment... I think your CPU mhz is 1191 MHz, 0.8396 nanosec clock but I am frequently wrong. If that is the wrong Mhz, type in your best guess as to your processor speed. It doesn't have to be exact, but if you know it is around 800, say 800. Please note that some processors, such as the P4, have a core which is double-clocked, so on those processors the reported clock speed will be roughly double the advertised clock rate. For example, a 1.8GHz P4 may be reported as a 3592MHz processor. Processor mhz [default 1191 MHz, 0.8396 nanosec clock] ===================================================================== We need a place to store a 5551 Mbyte file as well as create and delete a large number of small files. We default to /usr/tmp. If /usr/tmp is a memory resident file system (i.e., tmpfs), pick a different place. Please specify a directory that has enough space and is a local file system. FSDIR [default /usr/tmp] ===================================================================== lmbench outputs status information as it runs various benchmarks. By default this output is sent to /dev/tty, but you may redirect it to any file you wish (such as /dev/null...). Status output file [default /dev/tty] ===================================================================== There is a database of benchmark results that is shipped with new releases of lmbench. Your results can be included in the database if you wish. The more results the better, especially if they include remote networking. If your results are interesting, i.e., for a new fast box, they may be made available on the lmbench web page, which is http://www.bitmover.com/lmbench Mail results [default yes] OK, no results mailed. ===================================================================== Confguration done, thanks. There is a mailing list for discussing lmbench hosted at BitMover.
