## 2015-12-07
- Atmire sent [some fixes](https://github.com/ilri/DSpace/pull/161) to DSpace's REST API code that was leaving contexts open (causing the slow performance and database issues)
- After deploying the fix to CGSpace the REST API is consistently faster:
```
$ curl -o /dev/null -s -w %{time_total}\\n https://cgspace.cgiar.org/rest/handle/10568/32802?expand=all
0.675
