![CPU usage week](/cgspace-notes/2019/04/cpu-week5.png)
- For future reference, Linode mentioned that they consider CPU steal above 8% to be significant
- Regarding the other Linode issue about speed, I did a test with `iperf` between linode18 and linode19:
```
# iperf -s
------------------------------------------------------------
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
------------------------------------------------------------
[ 4] local 45.79.x.x port 5001 connected with 139.162.x.x port 51378
------------------------------------------------------------
Client connecting to 139.162.x.x, TCP port 5001
TCP window size: 85.0 KByte (default)
------------------------------------------------------------
[ 5] local 45.79.x.x port 36440 connected with 139.162.x.x port 5001
[ ID] Interval Transfer Bandwidth
[ 5] 0.0-10.2 sec 172 MBytes 142 Mbits/sec
[ 4] 0.0-10.5 sec 202 MBytes 162 Mbits/sec
```
- Even with the software firewalls disabled the rsync speed was low, so it's not a rate limiting issue
- I also tried to download a file over HTTPS from CGSpace to DSpace Test, but it was capped at 20KiB/sec
- I updated the Linode issue with this information
- I'm going to try to switch the kernel to the latest upstream (5.0.8) instead of Linode's latest x86_64
