If I have a two sites that, combined, get about 125,000 page views monthly (that comes out to about 4,000 page views daily). The sites are powered by Wordpress, and it is being used as a CMS, it's not a blog. There are a number of plug-ins in use, on each site, about 10 or so. Each site also has a vBulletin forum in use, although there are rarely more than 10 concurrent connections, if even that many (total of 400 members, only 150 of which are active -- combined stats for both sites).
Currently the PHP memory limit is set to 16M. I'm wondering how high it could or SHOULD go? Granted, I would not want to ask for more than what is available. Would the site speed improve if it was upped to say 128M? Let's pretend that I have a 512MB VPS SLM (no burst). It would have Linux+Apache+Plesk.
Is that enough of a VPS? Would I need to go to 640MB, 768MB, or even 1GB of RAM? Budget is an issue, so "yeah sure, go larger" is not an easy decision. It's also stupid to buy what's not actually needed. Maybe 256MB-384MB would be good enough?
Now then, what if I wanted to use this on a Windows IIS6 system instead? Let's say that I decided to add an ASP.NET wiki or blog to one of the sites. Clearly, that would demand more RAM, and I think Windows itself likes to eat more RAM. The Windows box would also have either Plesk 8.6 or Plesk 9. What's the difference in base RAM use that should be accounted for?
Virtuozzo is desired for either solution, be it Linux or Windows.
My current situation is shared, Windows 2003 Plesk, for these particular sites, and these two specific sites are loading really slow sometimes. Other times I get partial loads, error 500, or pure "unavailable" issues. Other sites, same machine, just fine.
Even the vBulletin forums on the same domains load okay and fast, but the Wordpress sites crawl. It is IIS6, so use of WP-Cache/etc is pretty much impossible. I tried another cache, and it works -- but only for maybe 2 hours at a time, then something happens to it, and the cache quits. It's enabled, but it just stops functioning properly.
My shortlist of the moment includes KickassVPS, FutureHosting, and EuroVPS, for whatever new VPS plan that needs to be gotten. I've been watching the VPS offers threads for the past two weeks. I'm leaning hard to FutureHosting, for this one project, because of the Seattle NOC, since one of the site admins is close geographically, and he always has trouble with the current site's location (other side of the globe, for him).
I'm hoping some of the WHT experts have some good answers for this. I've been researching this for a while, both on WHT and off, but I can't seem to get a clear answer from reading alone.

How can I limit my dedicated server's resources ? For example, one of reseller provider's limits :
Quote:
Resellers may not use more than 2% CPU daily, 3% memory daily, run more than 10 simultaneous processes per user, allow any process to run for longer than 30 seconds CPU time, run any process that consumes more than 20% of available CPU at any time, or run any process that consumes more than 16 MB of memory. Databases are limited to 16 max user connections with a max query time of 8 seconds. Cron jobs must not execute more than once every 15 minutes and will be niced to 15 or greater.
From where or how can I configure these limits?

I know bluehost.com "sort of" does this. If you use more then x % of the total CPU or memory of the server, then your account will be limited automatically.
(A page is displayed saying that the page you're trying to view can't be displayed because it is using too much resources.)

I am trying to increase the PHP memory limit for all Plesk hosted sites.
I've updated the 'memory_limit' setting in /etc/php.ini
Then I ran
Code:
/usr/local/psa/admin/sbin/httpdmng --reconfigure-all
/usr/local/psa/admin/sbin/httpdmng --reconfigure-server
Checking a phpinfo() page on hosted sites I see that this setting has not been effective.
Checking some /var/www/vhosts/system/domain.com/etc/php.ini also shows the old setting, and I can see that these files have not been updated.
I note that all these domain php.ini files have been modified earlier today, all at the same time, so presumably some process did regenerate them earlier. All these files hae the "DO NOT MODIFY ..." heading
I realise that I can go the the domain in Plesk GUI and save the PHP settings to force an update, but is there anyway to force the regeneration of all of these files via CLI?

I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code:
root@server [~]# free -m
total used free shared buffers cached
Mem: 768 449 318 0 0 0
-/+ buffers/cache: 449 318
Swap: 0 0 0
Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory.

I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info

# uname -a
Linux server2.[url]2.6.18-128.1.10.el5 #1 SMP Thu May 7 10:35:59 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
Any idea that we can put more content into memory?

I just ordered a server from serverbeach that should have come with 2 GB but I see that this one comes with 8 GB
Unfortunately, I seem to be missing 7 GB of ram.
Installed Physical Memory: 8 GB
Total Physical Memory: 1 GB
Windows 2008 Server Web 32-bit
Now, being a 32-bit system, I should see 3-4 GB of ram right?
Any idea why only 1 GB is available for the OS?

I have a 512mb DV server with Mediatemple, which I am running 24 (ish) domains off (most of them static websites) and a teamspeak server. I would say MAX theres 10 users online at a time)
Now, I know its running out of memory because i get frequent QoS Alerts in plesk (kmemsize is apparently the memory size):
Oct 01, 2009 11:52:57 AMBlack zonekmemsize
I have attached my results (when I did top).
My questions are:
1. Should I be expecting to be out of memory running what I am?
2. Is there a way to see the problem domains (memory wise)?
3. Are there any ways I can reduce the memory? (I have followed this already:

4. Where is the memory usage coming from (I am finding it very hard to understand TOP)

I have a server with the following specs:
2 x Xeon 2.0 Ghz
4 x 2 Gb DDR RAM (8 Gb total)
I am trying many OS's but none of them worked as it should:
- Windows 2000: install aborted
- Windows XP: install aborted
- CentOS 4.4: install OK but Kernel panic on start-up
- CentOS 3.8: instal OK, only 3.8 Gb identified but the OS out of 8 Gb
- CentOS 3.8 64 bits: couldn't install, CPUs support only 32 bits
Add to this, the machine boots on EL Kernel on CentOS 4.4 but not on the SMP Kernel!
how I could run this machine on Linux with 8 Gb RAM?

My server has 8GB RAM, however processes are limited to 3GB it seems, even if most of the memory is free (I have a mathematical program that mmaps lots of files and needs more than 3GB). I read somewhere that this is because the OS is 32-bit, but that it could be bypassed with "hugemem" kernel support.
I doubt that my host would install this for me, so how can I do this myself without breaking my server I've never done anything like alter a Linux kernel. My current OS is:
Linux 2.6.9-67.0.20.ELsmp #1 SMP Wed Jun 18 12:40:47 EDT 2008 i686 i686 i386 GNU/Linux With WHM 11.2.0, cPanel 11.11.0-S16999, REDHAT Enterprise 4 i686 - WHM X v3.1.0.

I recently used these forums to help narrow my search for a reliable, competent host. I choose to avoid the larger hosts that sells unlimited or large amounts of disk space and bandwidth. I went with a smaller host that sells a 1GB disk space and 10GB bandwidth package that is reasonably priced. Keep in mind that my site is new and will likely only be visited by friends and family. I feel this package is appropriate for my needs.
Should I be concerned about a host that will suspend my site if I reach my limit? As a customer I would rather be notified to upgrade my account instead of having my site suspended. This practice of automatically suspending sites may very well be the normal procedure for most hosts thus the reason for my post today. Please share your opinions on this topic.

How do you limit CPU/RAM per account on a shared web server without virtualization? Something like what Dreamhost is now offering, for instance for user "john", assign 256MB of RAM and 10% of CPU. Without Virtuozzo and friends.
