VisualizaçõesMongoDB 3.2 wiredTiger performing better than MongoDB 3.4 wiredTiger
In my local I ran the iibench-mongodb benchmark with mongo 3.2 & 3,4 with wiredTiger. In my tests mongo 3.2 wiredTiger seems to be performing better than mongo 3.4 wiredTiger for both insert & query. Is this expected and why is the latest mongo performing worse than the previous release?
Environment -
- Mac OS X - 10.11.6
- Processor - 2 GHz Intel Core i7
- RAM - 8GB
- Mongo is started as
sudo ./mongod --storageEngine wiredTiger --dbpath /tmp/data/mongodb/wired2/ - The
/tmp/data/mongodb/wired2/is deleted before each test run and mongo is started again with the empty/tmp/data/mongodb/wired2/ - The test parameters for iibench-mongodb can be found in github.
- Mongo Version Used in test 3.4.1 and 3.2.8
- Java 1.8.0_77
Below are the results of my test. It represents the average of 3 runs:-

Yeah it seems that all the features included in the new versions are slowing the database
Benchmark between all versions: https://medium.com/@hartator/mongodb-4-2-vs-4-0-3-6-3-4-and-3-2-benchmarks-ee96a09ef231
But most of the benchmark are realized on standalone architecture, we can hope that performances are better on new version with a replicaset architecture, but i didn't found any benchmark so far..
