Hi

I've the following problem: 

I have too sites that are sitting on a vps platform on a leading ISP company.
Recently I've encountered a problem in which the sites became very slow (and sometime unreachable at all) and the CPU cycles in the server are very high (close to 100% even with one concurrent user...).
After eliminating problems that might origin in the application - like returning to default skin and clearing the log file (which was considerably big in both sites - much bigger than the DB itself), I've ran out of options and consulted with the system admin in the company that operate the VPS.
His opinion is that the DNN system is consuming too much resource from the VPS and therefore must be operate within its own dedicated server

Is that possible? Is there another reason that might result with this problem (considering that the two sites are mainly text, few scripts and very few if any CPU consuming applications)?

Here are the server details:
Windows server 2003R2 Data Center Edition, Service pack 2
Intel(R) Xeon(r)CPU, 5120@1.86GHz, 1/87Ghz, 512MB of ram.

The Sites: ihaklai.org.il, admati.org.il

Eran:

Please confirm the amount of Ram on the server.  Is it really 512MB???  If that is the case, that is your problem right there.  Trying to run a production site on 512MB of Ram is kind of ridiculous, specially with Win 2003 Data Center Edition.  You need at least 2GB for the server to run smoothly. 

All the extra work you see the server doing is just to manage memory and the memory pages in and out of the swap file because the Ram is not sufficient.  I'm willing to bet that the hard disks have a lot of activity all the time also correct?

Until you increase the Ram it will be almost impossible to do any kind of fine tuning.  I have a server with much slower CPUs but with a lot of Ram and it works great.

I know that DNN can run successfully on a VPS system, in fact I ran 5 installations of DNN side-by-side on a VPS for 8 months without any issues.  These sites were running about 1200-1500 visitors per day total.

The key here is to validate a few things first of all with server configuration and DNN Configuration

1.  How much ram do YOU have allocated, this needs to be at least 1 GB at minimum

2.  Are you running SQL Server on the same box?  If so, did you remember to setup the memory limit?  If not, this will be a HUGE issue

3.  DotNetNuke configuration, have you modified the frequency of the expensive scheduled tasks, such as the Search Engine Scheduler.

4.  How large is your Event Log, clear it if it is large.

Once you have validated a few of these hopefully you have either identified the issue, or at least discounted a few things to help move forward.

If you have questions about any of the above feel free to drop me an email, msellers@iowacomputergurus.com, I do DNN performance optimizations all the time.

Yeah, 512MB won't cut it.

Take a look at perfmon and I bet you'll see lots of physical read/writes and your system is "swapping" memory to the drive(s) due to lack of RAM.

Another thing you can do is try changing your caching to FILE instead of memory, but I'm not sure if that will work either.

sorry if that's no help. :-)

It don't think that the ram is the issue here.

From what I see on the server - it does not uses all of the memory available.
I Thought that the problem relates more to the VPS configuration than the DNN.
and since the sites are OK now (don't know why...) - It seems that I was right (for now...)

 

THX guys for the answers
