No problem. Let me know if you have any other questions!

> Greetings Warren,

> The info on this page is still pretty relevant, but some parts are not quite 
> up
> to date:

> 
> For example, we'd recommend Tomcat 8 / Java 8 at this point. Also, ignore the 
> part
> about Solaris. We still use ZFS, but Linux can use that now, too. We have not 
> had a
> "bake off" between ZFS and EXT4, but a several years back we had one and ZFS
> outperformed the other file systems.
> 
> In general, though, the TDS is going to be bound by I/O, so anything you can 
> do to
> make sure that the TDS has maximum access to the disk is going to be good
> (for example, minimizing any other services that are heavy on I/O).
> 
> We have seen traffic become an issue on our TDS, in that the maximum number
> of network connections to our machine has been hit a few times. Usually this 
> is
> due to a number of slow connections downloading huge files using the 
> HTTPServer
> service on the TDS. Of course, this too can be somewhat mitigated by reducing 
> the
> number of web applications hosted on the same machine.
> 
> What kind of data are you going to be serving out? Real time, or archived?
> Format? This will play a role as well in terms of hardware.
