Hi,
i purchased i vps cloud coldfusion plan from HMS with
1GB ram...
i installed mysql, helicon isapi_rewrite 3 and
filezilla server which runs only when i want to
donwload/upload sth... moreover i use smartermail
Ofcourse i disabled mssql and the support team took it
out for good just in case....
for  couple of days or so the memory usage was up to
98%... some visitors no some crazy script or query
loading the whole imdb database just ordinary scripts
and queries... after some struggling somehow the memory
went down to ~70%(by HMS ofcourse)..
The day before yesterday the memory usage went down to
30%, yeah !!!!!


I really dont have any complaints from support team,
but i want to ask if this is sth ordinary??
So if its ok to be 70% with no visitors what its going
to be when there will be visitors?

[UPDATE]Moreover i purchased a linux vps to host my
databases. so in the coldfusion vps i run only
coldfusion and smartermail without the default memory
settings for the first!!! And still i see no
diffrence!!!PLZ YOUR OPINION

I also use vps from HMS.  I've found it best to only
run CF on the vps.  I use the vps for hosting all
websites, and a linux builder account for each domain
that needs email.  You should not run email on your vps
- too much liability for mail bounces if cf brings the
server down.

You'll benefit from reading mike brunt's blog posts
about server and jvm settings:

Also, assuming you're on Windows/iis delete the
'application' in iis associated with each site.  You
don't really need the app pool overhead - nice feature
for .net sites for process isolation but you can save a
lot of physical memory by not using it for cf sites.

The man of the day ladies and gentlemen...
THANK YOU SO MUCH...

one question though.. are you using gzip compression?
actually two: do you use mssql or mysql?
a third?: your databases are located on the same machine?

I use shared database hosting for MSSQL - not very
familiar with mysql, otherwise i'd probably use that on
the linux builder accounts.

for a while i used an additional vps (256mb) for
running mssql databases only, but found it didn't cut
it for performance - most of my sites run the MURA cms.

I don't use compression right now - I'm waiting until I
get a newer vps with server 2008 and iis7 - most of my
sites don't have high traffic.

The other thing I do with the linux builder account is
for some image hosting.  For example, if you look at
melsa.org, you'll see that some of the images
referenced in the css file are on asset.melsa.org.  
This is a DNS cname for the linux builder account.  I
do this based on google page speed recommendations.

I'm not a server admin but even my local workstation with 9 applications running CF Development Server (CF8) isn't running more than 55% right now.

Cheers,
Chip

moreover what OS do you have? 2003 or 2008?
2008 has an extra cache which uses the unused memory..

with firebug i saw a difference with less queueing time,
and it 'felt' 50-100ms faster or so when refreshing
pages.
