big innodb_log_file_size

In this post, we’ll discuss what constitutes a big innodb_log_file_size, and how it can affect performance.

InnoDB and TokuDB on AWS

 | February 1, 2016 |  Posted In: Benchmarks, InnoDB, TokuDB

In a recent post, Vadim compared the performance of Amazon Aurora and Percona Server on AWS. This time, I am comparing write throughput for InnoDB and TokuDB, using the same workload (sysbench oltp/update/update_non_index) and a similar set-up (r3.xlarge instance, with general purpose ssd, io2000 and io3000 volumes) to his experiments. All the runs used 16 threads for sysbench, and the following […]
