What do you think of this vps?

Hi, i’ve to choose a good vps and i’ve found this:
http://www.adiungo.com/hosting/
what do you think (XHP) ?
And about centos with rails and postgres what do you think?
the problem maybe is that i don’t know centos, but i can learn it… :slight_smile:

ops, fedora, not centos…

One of the downsides of Postgres with the typical PHP stack is
connection latency.

We actually switched from MySQL to Postgres on
http://www.funadvice.com and the site was faster and more stable.
Running Rails in production mode keeps a persistent connection open to
Postgres for each mongrel running.

So Postgres is a great choice for rails/mongrel applications.

Isn’t this usually how mysql and rails would work? Usually mysql will
let a connection ‘sleep’ a certain amount of time, so the connection
doesn’t need to be reopened for each request. You can configure the
sleep time, but I would guess any normal setting like 60 seconds would
be more then enough for the connection to hang out open for rails to
continue to reuse.

You are correct. But the original poster mentioned Postgresql, and I
just thought I would share my experiences on a similar stack that he’s
considering.

I also use MySQL on other projects along with Postgresql.

My mistake then - I thought you were saying postgres would maintain a
connection whereas mysql wouldn’t.

thanks,

Hi Eric,

if I were you I would do a quick comparison of this VPS with the VPSes
at http://www.railshostinginfo.com . Most of the VPSes listed there are
used quite a lot by Rails developers.

Kind regards,

Nick

I just started using slicehost (http://www.slicehost.com/) where you
can choose from the major linux distros (centos, debian, fedora,
ubuntu, gentoo). A nice feature is that you can rebuild your slice and
start from scratch (which I used like five times before getting it
‘just right’). I’m running centos with rails and mysql, I have recipe
I can post if you like.

Don’t know which is the best linux to use, RailsMachine use centos,
EngineYard use gentoo, pick your poison.

Eric-

I haven’t tried the place you are talking about myself at all. But I
did want to say that they don’t appear to use Xen, which means they
use something like OpenVZ that allows the hosting provider to
oversell resources. Xen does not allow for oversold resources and is
the performance leader for vps’s

hi, i’ve already seen it, but i didn’t found anything like that:

  • 786 mb ram (1536 burstable)
  • 30 gb hard disk
  • unlimited transfer
    for just 25$ (biennially)

it’s quite cheep comparated with other vps on railshostinginfo
i asked to know if anyone have tryed it and if it’s good… :slight_smile:

Hey eric,

It’s a bit more expensive, but we’ve been testing out a TextDrive /
Joyent Accelerator to see what we can get out of it for hosting Rails
apps. I’m pretty happy with it – we finished our testing tonight and
we’re gracefully handling 50 connections per second on a moderately
complex application, using Rails, Mongrel, nginx, and PostgreSQL. Of
course, the big caveat is that we’re doing the benchmarks in off-peak
hours where we can burst the whole box. :wink:

There’s more info on my blog:

http://peat.wordpress.com/2007/03/14/rails-joyent-accelerator-benchmark/

All that said, the biggest issue people seem to have with the
Accelerators is that they’re running Solaris – it takes a little
getting used to if you’re coming from the Linux/FreeBSD world. The
most obvious differences are filesystem layout and package management,
but since you’d be learning that for a new distro anyway, it’s not too
big a hurdle.

they use virtuozzo… the problem is that with xen and the same price
will be just 256 mb, 10gb and about 100gb transfer… do you think that
this will be better than 786 mb? maybe the problem is that if anyone
burst the ram he’ll takes part of “my” ram, but if it’s guaranteed i
think it won’t go down 786mb…what do you think ?
another cool (but more expensive) is slicehost:
1024slice 1024MB 40GB 400GB $70
and they use xen…

Oh – I forgot to note that our configuration for the 50/req/sec is
without any optimization what so ever, with a moderately complex Rails
app that hits the database pretty well, and compresses content on the
way out. Static content gets pitched at several hundred requests per
second, if that provides another useful reference point.

http://blog.craz8.com/articles/2006/12/25/openvz-redefines-ram/

Xen based systems allow paging in your VM, so an app that allocates a
lot of memory and uses very little of it - Apache, MySQL et al - can
work with less Xen memory, but use a lot of Virtuozzo memory.

So, in summary, a 768MB Virtuozzo system maybe similar to a 256MB Xen
system depending on load.

That said, I’m running in a 512MB OpenVZ VM that runs very well at
Quantact.com. 256MB was too small for 4 mongrels (2 different apps),
MySQL, Monit, Nginx, Postfix. Adding Apache put me up to my ‘burst’
limit too!

ok, i think i’ll go with xen :slight_smile:
thanks

Seem like good specs and pricing. But I also agree with the point
about Virtuozzo and would suggest Xen. I’m with slicehost and they
have been excellent with similar great prices. Also from what they’re
website says Adiungo’s servers are located in Switzerland, I don’t
know if thats an issue for you?

agree, switzerland is a bit outside.

I’m on slicehost too and the service has been effortlessly easy.

they also seem to know what they’re doing which is a major plus!
