Title: Speed up yum updates with yum-presto
Post by: guest22 on February 05, 2015, 07:05:15 AM: Hi,

just wanted to mention the yum-presto yum plugin for SME Server 9. It is available from the base repository. (yum install yum-presto)

I haven't had the chance to test thoroughly yet, but it should reduce download sizes up to 80% for it only downloads the delta between existing rpm and new rpm. A yum update after initial install should save you time and bandwidth.

If you're going to have a go with it, please let us know and we will wikinize it.

RequestedDeletion, could you please raise a NFR? if this plugin is available from upstream repo, it could be included in the iso
Thank you

Post by: brianr on February 05, 2015, 10:54:08 AM: "No package yum-presto available"

Any ideas?

I already use this for my Fedora 20 Desktop - it certainly works well.

Post by: Stefano on February 05, 2015, 10:57:38 AM: installed right now on 3 SME9/64 (production), 1 SME9/64 (test), 1 Centos 6.6 (production) 1 Nethserver 6.5 (production) without any issue :-)

can you post here some more info? arch? command you gave?

Post by: Daniel B. on February 05, 2015, 11:05:52 AM: Just FYI, it's not always faster, depending on the bandwidth available and the power of your CPU. With 30Mbps available for example, it's usually much faster to disable presto, rather than downloading just delta rpm and rebuilding them locally (which is a CPU intensive operation). But it can be interesting if you pay per GB downloaded

oops - sorry just realised - that machine is SME8 - I'll try it on an SME9....

ok, that works fine, and I did an update which ran through - reduced the download by 71% (it said)

If we can fine tune our findings, we might have a winner to document and to open up a NFR.

well.. nowadays cpu is not a problem, bandwidth is (at least here in Italy)
and it will be usefull after the first setup

In light of hurry up the next ISO because of many (upstream) updates and careful creation of a new ISO, this is exactly why I looked at yum-presto. We may be able to satisfy both worlds.

In France (just next to Italy), most of the time bandwidth is not an issue (got 100Mbps at home + a 6Mbps backup), especially if you choose to host your server in a DC (where you can easily have 1Gbps)

Title: Re: Speed up yum updates with yum-presto
Post by: Stefano on February 05, 2015, 11:43:46 AM: ROTFL.. 100Mbps is a dream.. :-)

in any case, the bottleneck is usually wan connection, not cpu.. I vote for a NFR :-)
Title: Re: Speed up yum updates with yum-presto
Post by: guest22 on February 05, 2015, 11:45:55 AM: 150Mbps here... Just received a notice that it will be upgraded to 180 for free....

Title: Re: Speed up yum updates with yum-presto
Post by: Daniel B. on February 05, 2015, 11:49:24 AM: Could have up to 400Mbps for a few more $$ (~45€/month) if I ask for the new modem (DOCSIS 3) :-D
Title: Re: Speed up yum updates with yum-presto
Post by: guest22 on February 05, 2015, 11:51:12 AM: Love you too :)

If I can just receive the best recipe for Gnocci, Aligot, saussise de Toulouse and Coq au vin, I would be a happy man and I will blow you over some bits.

Title: Re: Speed up yum updates with yum-presto
Post by: Stefano on February 05, 2015, 11:52:39 AM: in my area (north-east of italy, near Venice, a rich area) we got 20/30Mbps..

Post by: Stefano on February 05, 2015, 11:54:07 AM: ok.. guys, break is over.. we're going OT..

RequestedDeletion, can you please open a NFR? TIA
Title: Re: Speed up yum updates with yum-presto
Post by: brianr on February 05, 2015, 11:59:59 AM: 30-60Mbps is the norm in the UK, using FTTC (Fibre to the cabinet).

ADSL2+ gives up about 20Mbps if you are close enough to the Exchange, but do not have FTTC.

Otherwise ADSL is 1-6Mbps.

Sorry Stefano for the OT post - I did feel that the UK was missing out!!
Title: Re: Speed up yum updates with yum-presto
Post by: Stefano on February 05, 2015, 12:19:44 PM: Brianr, don't worry.. your post confirms that that feature would be usefull for countries where bandwidth is not like in france or germany ;-)
