SSDs and Application Performance: What’s the connect?
Before I even start getting into the details of SSD and application performance, a foreword about what is the intent behind writing this post. This post will mostly run you through understanding of performance problems in data center that use magnetic disks, will touch base on major factors that govern application performance. Is network latency the culprit? Applications are slowed by network latencies: is now quite a known fact. Apps that run over a network are hugely impacted by network and storage levels too. This typically is followed by I/O bottlenecks popping up as more and more users login to make the application work even harder. Traditional hard disk drive‐based systems incur performance penalty because of the high access times of hard disk drives. However, Solid state disks resolve this issue primarily with low access times and high bandwidth. Access Time = Command Overhead Time + Seek Time + Settle Time + Latency Direct impact on Application performanc...
