Abstract With the current rate of data growth, processing needs are becoming difficult to fulfill due to CPU power and energy limitations. Data serving systems and especially persistent key-value stores have become a substantial part of data pro- cessing stacks in the data center, providing access to massive amounts of data for applications and services. Keyvalue stores exhibit high CPU and I/O overheads because of their constant need to reorganize data on the devices. In this master thesis, we examine the efficiency of two key-value stores on four servers of different generations and with different CPU architectures. We use RocksDB, a key-value that is deployed widely, e.g. in Facebook, and Kreon, a research key-value store that has been designed to reduce CPU overhead. We evaluate their behavior and overheads on an ARM-based microserver and three different generations of x86 servers. Our findings show that microservers have better power efficiency in the range of 0.68-3.6x with a comparable tail latency and they incur 1.1-2.7x lower energy cost. However, microservers to be more cost- effective they need to have a purchase price several times lower, and typically around or more than 3x, than higher end servers.
