Forum OpenACS Q&A: OACS hosting plug
You get a virtual server, root access, pretty much like any other hosting option for openacs but half the price.
You're limited to 65MB of memory per process on the lowest pricing option so obviously you're not going to be hosting huge sites on it but for $15/m this is by far the closest I have seen to anyone matching the kind of pricing you see for Apache shared hosting. And obviously a virtual server is so much better than shared apache, there's no comparison.
I signed up Saturday. The last time I used anything BSD-related was SunOS in 94 -- goldvision is a freebsd shop -- so it's been a while. This is to say that I've sent several mails to mailto:firstname.lastname@example.org, including one before I signed up. The longest wait time for a reply was _maybe_ 10 minutes. That's including one Sunday and one late at night.
Frankly I'm pretty impressed so far.
A default OpenACS (depending on config) takes about 40MB RAM for the AOLserver process, plus a few MB per Postgres connection (although a lot of RAM is shared between the Postgres connections).
Busy sites (10GB traffic per month or more) usually take a lot more, up to 128MB per AOLserver process, plus Postgres connection overhead. Of course RAM usage is dependant on how much you cache, how much stack you use, number of threads etc. etc.
that is what I always been concerned about virtual server.
For a oacs installation with no big load, small traffic how is the performance?
and what about dotlrn also with small traffic?
In our (Zill.net's) case we ensure that there is always enough RAM to support the number of servers being run. That is really the only way to make sure that performance will be OK when running on a shared server.
Roughly 50MB per OpenACS instance is usually good (in our case, as mentioned before, the database server is on a different machine), plus 32-64MB for the operating system.
The dotLRN instance can take a little more RAM depending on configuration. Also the number of threads you are running can increase RAM usage.
Just to correct the record, AcornHosting's (http://www.acornhosting.net/devdeal) smallest package starts at $25 (not $30) and has more disk space and bandwidth than the $15/month package you're comparing it to.
If people are excited about a $15/month package, I can probably come up with one. It will not have the flexibility of being able to run a production and development instance at the same time (or two low-traffic sites at the same time), or being able to run apache/php and OpenACS while migrating from one to the other. Food for thought. :)
Here is the link (everything in German):
I am very happy with the performance I get from acornhosting.
I have a reasonably busy site - peaking at 2000 visits/day serving 160M/day data.
I get a full virtual server with root access, 2G disk, 20G traffic - so it's like I have my own machine for $25/month.
Cathy has fixed any problems I have had usually within a few hours any time I've had them including weekends.
