Well, a couple of forums and blogs seem to be consuming memory on the shared plan, so, a technician says it might be a good idea to go VPS. First, which one might be suitable, i dont have more than 2GB used and use around 20GB of badwidth, is it really possible that my site's are using that much memory? Second, if that might be the case, what is the difference between those VPS plans, they confused me immediately  Third, what should i learn to manage a VPS, have always been in a shared plan, so, I guess I'd have to learn several things... i guess.  thanks in advance |

I would suggest checking out the new Xen Starter VPS hosting plan here: http://www.lunarpages.com/xen-virtual-private-server/Think it would delver the most "bang for the buck" and is also the most affordable VPS hosting plan we provide. To explain resource usage a 'bit better, you can think of your hosting server/hosting account as a computer with programs. One program might be being used, and being worked so hard that no other programs can run right. If you find yourself in these shoes, then moving to a VPS hosting platform where you have more elbow room will possibly eliminate the issue. As for learning how to do this, that and the other - best way is to ask here, or search through previous posts. There are a lot of great questions and answers all over this forum. Hope that helps some! |

If your site is having memory consumption issues on shared where there are 6GB or more memory per shared machine, I highly suggest going to at least the Xen Pro plan where you have 1GB of memory and then can add more. I would never suggest the lowest level VPS plan for someone having memory issues on shared, since 256MB of memory on the lowest level Xen plan will never work for your site.
Memory is not the same as bandwidth and disk usage at all. Memory is the amount of RAM your site's scripts take to run on a server. If you are using MySQL with those scripts, then the MySQL queries, site activity and coding all take a role in how the site uses RAM. I'm not certain where the misconception comes from that many people, not saying just you have the misconception here as this happens a lot, about disk space and bandwidth correlating to Memory and CPU consumption directly. Obviously, high traffic can increase the RAM usage, but high RAM can also be caused by poorly coded scripts or slow queries for your MySQL databases. You could barely have any traffic and if the script isn't optimized well, it ends up using a lot of Memory.
Basically, I really suggest looking at the Xen Pro plan to ensure you can add RAM to the server. 256 MB is simply not going to work for your site if you are having issues with the shared server memory. I also highly suggest having us help you optimize Apache and MySQL on your new VPS after you get it setup. You might well save yourself grief down the road in how well the site runs by doing this at the beginning.

thanks for the replies, well, I dont think my forums are too crowded, sometimes they have 50+ users and i limited galleries for registered users. Also I have a couple of blogs and joomla sites, but also, not very popular, more personal... or that0s what i think. Sites advertisment will pay for the starter VPS, that might be my pick right now. But it seems now I'll be responsible of how i manage the VPS. That's where I have concerns, I'll be the one installing PHP, MySQL and Apache? Or I'll be in charge of updates and addons? What tools will i need to manage the server and what does it mean using my onw nameservers? should i have nameservers for each domain i have? My main domain is hosted in LP, will they help me with that?  |

I don't don't agree with the above posts that definitely need a massive VPS plan because you're getting kicked off the shared servers for resource consumption. It doesn't take much to go over your "shared" amount, and the admins will start moving your account around to different servers, and eventually tell you you need to upgrade.
Also, it's very common for forums to be "attacked" by spammers, and while they aren't showing up as legit users, they can be using up a ton of resources trying to inject spam posts. If you are running a forum that is updated and current version, and it's not THAT busy, but it's using a ton of resources, I would guess it's SPAM attacks.
I would spend some time checking your access logs first to rule out the SPAM attacks.
Also, memory issues can be caused by several things, but many times a little looking around you'll find something you can turn off or optimize to save resources...and $$$ spent on hosting. I agree with Tristan, but instead of just making sure you have enough RAM, I'd rule out the possibility that your scripts can't be optimized/fixed/turned off to save the memory you do need.
List all your sites, software, and versions here like this :
Site 1 : Joomla 1.5.15
Site 2 : Joomla 1.5.12 + vBulletin 3.2
etc......
Bottom line is, time/money you spend on optimizing/fixing your scripts MIGHT be better than just paying for more hosting resources.

Yeah, I've been considering that also, at least one of the forums has received several spammers in the last months. I'm running vbulletin 3.8.4 on both and i'm already planning my move into the new vB 4 Both Joomla are 1.5.15 and wordpress blogs are up to date. Checked a couple of logs and it seems google adsense bot enters a lot, i used robots.txt but i was wondering how to limit that bot from accesing, but still letting it see what is in the website, after all, those ads are the one paying everything. Still, not enough to move to VPS without holding on some major updates as i did with vb 4. Now, it seems everything is unmanaged and i'm not sure if i'll have cpanel here. Start searching and some webhosts add cpanel and some sort of management for less than 30 a month, that confused me a lot more.  |

I would guess it's your vBulletin installs that are the root of the memory issues (depending on the Joomla/Wordpress extensions you are using)
You might start searching around vB forums looking for memory issues/optimization techniques. VB is a beast of a script and has a lot of features that run via CRON.php that can be disabled depending on your situation.
My core VB files were being SPAM attacked, and my CPU processes resource was WAY higher than it should be. (I don't remember how it affected my memory consumption) I had to hack VB core templates and rename the main PHP files so the bots couldn't find them.
Also, the LP Linux VPS can include cPanel or Plesk, something you need to specify when you order your VPS. When I first converted over, I was used to cPanel on LP shared...and originally wanted it installed on my VPS. But it was recommended I use Plesk instead, and I'm VERY happy I made the switch. Plesk is awesome and very easy to learn.
All you have to do is order a Linux VPS with Plesk. Request the admin update Plesk, PHP, and MySQL. You'll also want suPHP(or similar) installed. LP admins can do all this for you. They charge $75/hr, but it's worth having them properly setup your VPS if you're new to managing a Linux install.

I know this hasn't been posted to in a few days, but I just got back from my vacation . My recommendation would be to start out with a Xen starter plan, and see if you need to upgrade your memory from there. The Xen VPS' allow for upgrades of memory, cpu and hard disk, so it really can be customized to fit your needs.
I agree with conga3, in that you will need to most likely need SuPHP installed, as most CMS (like Joomla, Wordpress, and VBulletin) require that they can write to your files. There are of course other ways to do it, but SuPHP makes it easier and a little more secure.
VBulletin can be a bit of a resource hog, all on it's own with out any help from people trying to cause issues with it, especially if you have the search function turned on and someone searches for a really general term on your site. Also you mentioned ~50 users, but how big is your database at this point? that can also cause your memory consumption to climb if your database gets too large from old posts.
For what it is worth, I personally like LunarPanel. It may not have some of the frills of Cpanel/Plesk but it is easy to understand, easy to modify and comes with a good base set of functions and programs including spam assassin, php5, and phpMyAdmin.
Finally, if you are worried about managing your VPS, we do offer managed hosting packages to help. With Manged Hosting Lite, we monitor your VPS, if services fails or the VPS crashes we restart the service and try to find the cause of the issue at the time it occurs. Managed hosting Intense covers installation of a firewall, updates to the server's software, setting up the automatic FTP backups and one free application/script install.
If you have any other questions, let us know.

Oh, so there is a control panel after all, I was worried ther would be nothing to check stats or program versions.
Guess i can learn how to use ssh to update, and maybe i'd consider the lite management.
Somehow I'm worried about the price, but I know in the end is better to stick with LP, once I changed because of the price issues and wasn't the best idea.
Will contact support and see what can they do for me to migrate my acount.
thanks

Well, contacted support, it took almost 2 days to answer, and then they answer a lot of strange things, no doubt it was almost a copy paste. Asked for VPS and instead they referred to dedicated plans, in the end they confused lot more.  |
