Recently I've been having server troubles lately
and I wanted to see if
anyone else was in a similar boat and how you overcame it. Because of
these server issues, it's putting me in a difficult situation and I
don't want to give up on a wiki I've been working on for the last 3
years. I'm hoping to get some advice from others who run their own
wikis, especially high traffic wikis.
-Front page runs wordpress (http://www.koreanwikiproject.com
however not much of the traffic goes here.
-Most of the traffic goes to the wiki on the site:
-I get less than 2,000 hits a day.
-I was on the shared dreamhost plan for a few years, until dreamhost
couldn't handle the wiki anymore. Lots of time outs and processes
getting killed for exceeding my shared memory capacity recently.
-In the last week I switched to a Virtual Private Server (VPS) on
dreamhost (two VPS actually: one is a regular VPS, the other is for
mysql).-For the first week dreamhost gives you 2300mbs of memory to work
with to gauge how much you need exactly. I turned on php caching using
Xcache and this helped performance a lot. Memory usage is usually under
400 mbs, but I get these huge spikes sometimes (even exceeded the 2300
mbs given initially). Here is an image of my memory usage (does it every
20 mins I believe):
-The problem is the way dreamhost handles alloted memory over usage: It
reboots the server. I don't understand why they do this, but they
explained it was to protect the physical memory. This is annoying
because anyone downloading anything on the server gets their connection
severed and the site goes down for a short time. In fact I don't see
this happening much to other websites.
I know some of you guys who get a lot more than 2,000 hits and even have
semantic wiki installed and still have done fine. Meanwhile, I'm not
sure I want to pay $36 a month for 2 VPS servers (One is a regular VPS,
the other is for mysql) that is going to have it's connection severed
several times a day due to memory spikes. At the same time I don't want
to give up on a wiki I've been working on the past 3 years, so surely
there must be a better way than me having to pay $100 a month for my own
server, especially when my traffic isn't that high. Some advice from
others who run wiki sites would be really appreciated and even
comparisons on what you guys are running with the amount of traffic you
get if possible.
A lot of us just run with a small single VPS/Cloud server like on Linode
or Rackspace cloud.
It's not the best performing sometimes. But the traffic weight and cost of
a single small wiki doesn't really justify running two servers.
You kind of need to be running multiple wikis (or one insanely large one)
to justify the server separation.
