I have a mix of Windows, Linux and Mac clients running Time Machine backups in addition to standard SMB and NFS file access. The NAS itself has plenty of disk space and plenty of RAM but lately its performance has been abysmal and its gotten worse with every client I’ve added to the network.https://leonroy.com/2015/10/storage-benchmarking/Thu, 29 Oct 2015 15:52:35 +0000https://leonroy.com/2015/10/storage-benchmarking/A little knowledge is a dangerous thing. Or so the saying goes. When specifying and buying computer hardware it saves time and money knowing the level of performance you get with your existing equipment and the performance you can expect from your new purchase. There are numerous metrics to measure but in order to obtain meaningful results (relatively) quickly I personally focus on CPU, memory and file and network I/O.
