We note that for MongoDB update latency is really very low (low is better) compared to other dbs, however the read latency is on the higher side. The latency table shows that 99th percentile latency for Yugabyte is quite high compared to others (lower is better). Again Yugabyte latency is quite high. Conclusion.

SLOG: serializable, low-latency, geo-replicated transactions Ren et al., The challenge with strict serializability (or even just serializability on a regular DBMS) is that it requires coordination, and as we know, coordination kills performance. That’s where SLOG (Serializable LOw-latency, Geo-replicated transactions) comes in.
