[jbosstools-issues] [JBoss JIRA] (JBDS-2730) Faster download of updatesite content via akamai

[Nick Boldt (JIRA)]

    [ https://issues.jboss.org/browse/JBDS-2730?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13008661#comment-13008661 ] 

Nick Boldt commented on JBDS-2730:
----------------------------------

Using the above script, results indicate that a 296M update can be done in under 2.5 mins the first time, then ~30 seconds for subsequent tests. 

I believe this data is inconclusive since the downloaded artifacts appear to be cached somewhere on disk. Whether I was pulling from the actual server (209.132.182.70) or the staging edge server (23.35.182.29), the results were the same, suggesting that JBDS was simply copying local files rather than re-downloading them each time.

Will need to re-run these tests on another machine to get a baseline for how long it takes to do the install when Akamai is not involved.

But a 2.5min install is very fast IMHO for nearly 300M of downloaded & unpacked files.

Before: Features + plugins folders: 547M, 613M for whole JBDS install folder
After update to CR1b: Features + plugins folders: 827M, 909M for whole JBDS install folder
Growth due to update: 280M - 296M

Test 01
Update to CR1b using devstudio.redhat.com.edgekey-staging.net server at 23.35.182.29 from:

https://devstudio.redhat.com/static/updates/8.0.0/jboss-devstudio-8.0.0.CR1b-target-platform/
https://devstudio.redhat.com/static/updates/8.0.0/jboss-devstudio-8.0.0.CR1b-updatesite-core/

1:55pm to 1:57:30pm = about 2.5mins

Test 02
Update to CR1b using devstudio.redhat.com.edgekey-staging.net server at 23.35.182.29 from:

https://devstudio.redhat.com/static/updates/8.0.0/jboss-devstudio-8.0.0.CR1b-target-platform/
https://devstudio.redhat.com/static/updates/8.0.0/jboss-devstudio-8.0.0.CR1b-updatesite-core/

2:01:38pm to 2:02pm = about 30 seconds

Test 03 
Update to CR1b using devstudio.redhat.com.edgekey-staging.net server at 23.35.182.29 from:

2:05:28 to 2:06 = about 35 seconds

Test 04
Disable edge server in /etc/hosts, disable VPN, and pull from public server at 209.132.182.70 using:

https://devstudio.redhat.com/updates/8.0-development/

2:13:50 to 2:14:12 = about 25 seconds

Test 05
Remove ~/.eclipse folder, disable edge server in /etc/hosts, disable VPN, and pull from public server at 209.132.182.70 using:
