I'm in need of benchmarking the storage system I am developing. I suppose I could cobble up some scripts and programs to do it. But I'm guessing there are pre-existing benchmarks for disk i/o. I know there are really complicated ones that measure things like Oracle transactions but I am hoping for something rather simple that just focuses on disk i/o performance.

Any suggestions?

I just finished a benchmark project a few weeks back. This should help: AC&NC | RAID.edu - Disk I/O Benchmarks - UNIX Benchmarks

Someone should really collect these links in one location. If only there was such a place to do that and maybe prizes involved?

Thanks for the link.

Re: collecting the links. Can the admin put some sort of ticky mark on the articles that have useful links? Then in the search, have these ticky marks show up somehow. So, Joe User comes to this site, does a search, finds 20 hits but can see that the two hits with ticky marks are probably the ones he wants to look at.

The only other thought is to have a seperate forum for threads that start with a link.

Hey! You might want to look at MacOSXHints.com. They have a system where users submit "hints" that go on the front page. The hints are sent to the admin. The admin then publishes them (so they are screened). Users can add comments to each hint.

Also, I've added a few links to my site that I did not duplicate here mostly because the links I found were specifically for hard core kernel developers. I wasn't sure how many of those are using this site.

Last -- and then I'll get back to work. I've found that a lot of users do not know where the IBM AIX pubs are. Those would be nice links to add as well.

I don't mind adding links. I guess I just wasn't sure where to add them.

You know, its not a bad idea for new sysadmins to learn kernel internals. One of the best books I've found on the subject on the inner workings fo the kernel and nuts and bolts level memory management is called "The Magic Garden Explained". My copy is about 10 years old. Don't know if there is an updated edition, but its well worth the time to read.

excellent, have just navigated to the page and downloaded bonnie++1.0.3a

thanks

Has anyone been able to build bonnie++ on AIX?

I'm trying to do it on AIX 5.2 with gcc 3.3.2 and the configure gives the following complaint:

checking for g++... g++
checking for C++ compiler default output... configure: error: C++ compiler cannot create executables
See `config.log' for more details.


Thanks!

Two thoughts:

1) maybe you have something called "c++" in your path that is not really a C++ compiler and/or it is broken.

2) what does config.log say (at the bottom)?

It appears as if configure finds g++ and then tries to find c++.

I have not tried to compile Bonnie yet. I plan to "soon" but it keeps getting pushed back. But I'm using g++ 4.0.2.

Here's my config.log. It seems to be executing 'g++ --version', which works but then later it tries 'g++ -V' with no other parameters and it fails the whole thing. I don't know enough about 'make' to know why. It doesn't really make sense to me. Anyway, I try 'g++ -V' on the command line and sure enough, it doesn't work there either.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.57. Invocation command line was
