LVM, RAID, XFS and EXT3 file systems tuning for small files massive heavy load concurrent parallel I/O on Debian

Thousands concurrent parallel read write accesses over tens of millions of small files is a terrible performance tuning problem for e-mail servers.

You must understand and fine tune all your infrastructure chain, following the previous articles for data storage and multipath on Debian 5.x Lenny.

We reduced the CPU I/O wait from 30% to 0,3% (XFS) and 5% (EXT3) with these combined previously undocumented file system tuning tips.

Virtualbox 3.0.2 bridged network bug workaround

VirtualBox 3.0.2 has a nice and easy bridge network configuration GUI.

But it does not work.

Read the workaround.

The new VirtualBox 3.0.2 has a nice and easy GUI interface for bridge network setup.

Compare with complex setup here, here, here, and you will realize it was a BIG improvement at usability from older versions.

BUT it does not work at its defaults.

Worse, it fails silently. Guest OS simply does not reach outside network. No meaningful hardware or software error logs or messages.

It is a known bug.

"Perryg" identified that the workaround, until the bug is fixed, is to choose one of the Intel/PRO 1000 virtual network device cards.

Your guest OS must have drivers for at least one of these 3 virtual cards available.

I am using Debian 5.x Lenny and it has drivers for the Desktop and for the Server cards.
