Many open source advocates would answer “yes.” However, assertions aren’t enough for well-grounded proof. That’s why in this blog post, we share the benchmark testing results from Alexander Korotkov (CEO of […]

Update on the InnoDB double-write buffer and EXT4 transactions

 | June 17, 2015 |  Posted In: Benchmarks, Hardware and Storage, InnoDB, MySQL

Many people commented on the post mentioning […]
