Mickael Istria commented on JBDS-2730:
--------------------------------------

Here is the result I get from Grenoble, France with an Internet connection that seems to download at something like 10Mbps.

* Download of a big file: _time wget http://devstudio.redhat.com/static/updates/8.0.0/jbdevstudiotarget-4.40.0.CR1-SNAPSHOT.zip _ , 484 MB
** Without Akamai (hitting regular devstudio,redhat.com)
### real 12m31.157s
### real 12m18.624s
** With Akamai (hitting 23.5.22.29 as devstudio.redhat.com)
### real 14m2.134s
### real 6m12.012s
### real 6m28.711s
Note that in the 2 last cases, my download speed goes from ~700kB/s to 1.3MB/s so it seems like I'm reaching my maximum bandwith and Akamai performance may be even better than the one I could measure.
* Download of muitliple file: Unzip a Luna JEE SR1 in a clean directory then _time java -jar plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar -application org.eclipse.equinox.p2.director -repository http://devstudio.redhat.com/static/updates/8.0.0/jboss-devstudio-8.0.0.CR1b-updatesite-core,http://devstudio.redhat.com/static/updates/8.0.0/jboss-devstudio-8.0.0.CR1b-target-platform -installIU com.jboss.devstudio.core.feature.feature.group_
** Without Akamai (hitting regular devstudio.redhat.com)
### real 7m59.433s
### real 7m46.935s
** With Akamai (hitting 23.5.22.29 as devstudio.redhat.com)
### real 6m5.297s
### real 5m41.244s
### real 5m49.267s
So it seems like we save 2 minutes out of 8, for a gain of 25% at installation on Luna SR1. I find it a bit low, but maybe most of the time is spent computing and unpacking rather than fetching artifacts.

> The updatesite used by marketplace should be behind akamai for smoother/faster download.
> Investigate using akamai/download.jboss.org backed storage.
