# Sentry Node SDK Memory Usage
This repo should provide a repro case + results for `@sentry/node` SDK found at: [https://github.com/getsentry/sentry-javascript/tree/master/packages/node](https://github.com/getsentry/sentry-javascript/tree/master/packages/node)
The file `express.js` in this repo was used to measure the following results.
The peak memory usage **decreased by ~80%** from version 4.5.3 → 5.x.x
Average memory usage **decreased by ~70%** from version 4.5.3 → 5.x.x
We are also able to **serve ~29% more requests/sec** from version 4.5.3 → 5.x.x
(When referring to 5.x.x I mean this work in progress branch [https://github.com/getsentry/sentry-javascript/tree/ref/make-sync](https://github.com/getsentry/sentry-javascript/tree/ref/make-sync))
## Installation + How to run:
`git clone https://github.com/HazAT/sentry-node-sdk-memory-pm.git`
`npm install`
or
`yarn install`
Then run the application with `node --inspect express.js` and open Google Chrome Memory inspection tool (can be found in the developer console).
The graphs in this repo where created with [https://github.com/watson/memory-usage](https://github.com/watson/memory-usage) used exactly as described in the repo (ran with `memory-usage express.js`)
Node version `10.15.0` was used for all the tests.
After the server is started, we run a ApacheBench command:
`ab -c 20 -n 10000 http://localhost:3000/`
Running 10000 Requests with 20 concurrent connections.
# Using 4.5.3:
