I'm echoing Charles' comments a bit. Specific filesystems are not good 
at everything. While it is my opinion that Lustre can be very stable, 
and like Colin stated the underlying hardware and configuration is 
crucial to that end, the filesystem may not be the best performing at 
every data access model.

Like every other filesystem Lustre has use cases where it excels and 
others where overhead may be less than optimal. Other filesystems and 
storage devices also suffer from "one size fits most".

Many here would likely be biased toward Lustre but many of those people 
have also used many other options on the market and ended up here.
