|

- I can definitely design a test plan on this!
|

|

## 2018-01-24
|
||||
|
||||
- Looking at the REST requests, most of them are to expand all or metadata, but 5% are for retrieving bitstreams:

||||

||||

|
||||
16 expand=all&limit=1
|

45 expand=items
|

775 retrieve
|
||||
5675 expand=all
|
||||
8633 expand=metadata
|
||||
```
|
||||
|
||||
- I finished creating the test plan for DSpace Test and ran it from my Linode with:
|
||||
|
||||
```
|
||||
$ jmeter -n -t DSpacePerfTest-dspacetest.cgiar.org.jmx -l 2018-01-24-1.jtl
|
||||
```
|
||||
|
||||
- Atmire responded to [my issue from two weeks ago](https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=560) and said they will start looking into DSpace 5.8 compatibility for CGSpace
|
||||
- I set up a new Arch Linux Linode instance with 8192 MB of RAM and ran the test plan a few times to get a baseline:
