I work in a computer company which sells computer configurations and parts of them. And I want to give a choice to customers. If they want to buy a PC with Linux installed, not Windows.

Windows blows. I'm poor so unix is looking like a great alterative (expecially after my former roommate showed me most of the things it can do). Right now I'm looking at Debian or some other Unix kernel that would run nicley on my computer.
But the problem we had with installing it while he was... (3 Replies)

Hi,
I have a simulation program which creates two threads and I would like to know if I can measure the time of each individual thread. Threads communicate (I use pthread to manage them) and I want to measure communication time. I found a solution with clock_gettime and CLOCK_THREAD_CPUTIME_ID... (32 Replies)
Hi
For our load testing , we are using stubs (unix shell script) which send the response to the request coming from the application. As the unix stub is single threaded , it is responding to only one request whereas multiple requests come in parallely.
I haven't worked on thread concepts... (5 Replies)

filebench
filebench(1) USER COMMANDS filebench(1)NAME
filebench - interprets WML script and generates appropriate filesystem workload
SYNOPSIS
filebench [-f <filename>] [-h]
DESCRIPTION
Filebench is a file system and storage benchmark that allows to generate a large variety of workloads. Unlike typical benchmarks it is very
flexible and allows to minutely specify (any) applications' behaviour using extensive Workload Model Language (WML). Filebench uses load-
able workload personalities to allow easy emulation of complex applications (e.g., mail, web, file, and database servers). Filebench is
quick to set up and easy to use compared to deploying real applications. It is also a handy tool for micro-benchmarking.
Filebench includes many features to facilitate file system benchmarking:
o Multiple workload types support via loadable personalities
o Ships with more than 40 pre-defined personalities, including the one that describe mail, web, file, and database servers behaviour
o Easy to add new personalities using reach Workload Model Language (WML)
o Multi-process and multi-thread workload support
o Configurable directory hierarchies with depth, width, and file sizes set to given statistical distributions
o Support of asynchronous I/O and process synchronization primitives
o Integrated statistics for throughput, latency, and CPU cycle counts per system call
OPTIONS -f <filename>
use specified file as an input instead of stdin
-h Display verbose help
EXAMPLES
Run filebench interactively:
$ filebench
Start filebench interactive shell, filebench prompt will appear after that.
filebench> load fileserver
Load fileserver personality using load command.
filebench> set $dir=/mnt
After personality is loaded, tunables of the workload personality can be set. Here we change the benchmark directory to /mnt where
the file system we want to benchmark is presumably mounted.
filebench> run 60
Start workload for 60 seconds. After 60 seconds of the run the statistics is printed and Filebench exits.
Run filebench non-interactively:
filebench -f /usr/share/filebench/workloads/fileserver.f
Run filebench non-interactively, however, you need to add 'run <time>' to the end of the workload personality file before calling
filebench.
EXIT STATUS
0 if OK,
1 if workload file is not found.
