Apache :: Use Disk To Enhance For Page Cache And Database Cache For Disk
Apr 24, 2013I use apache with CentOS VPS hosting for my blog. I only host one blog in this VPS account. I have 1.5GB RAM and I have 7, 500 page preview per day. My page loading time is 2-3 seconds (according to the pingdom tool).
I want to know what is the best performance (faster web page loading) W3 Total cache option for VPS hosting blog. Currently I use Disk to enhance for page cache and database cache for disk.
Xl Host For A Core2duo Server
Jul 21, 2008I was thinking about getting a core2duo for a vps node and I was thinking that I need quite alot of IP addresses and was hoping that the delivery time on the IP addresses were quite small. I need it for hypervm due to the fact that its alot cheaper than Virtuozzo.

Oct 5, 2008I have a Quad Core Xeon right now that I had set up with RAID 1. I'm getting horrible Disk I/O rates for this drive, 1.57MB/sec sequential write speeds. I'm having slowdowns that seem to be database related and more specifically I/O related. I run both my webserver (IIS/ASP) and my database (SQL SERVER 2000) on this Quad Core Xeon box with 4GB RAM. The disk I/O is killing me. I see that I have plenty of CPU cycles and plenty of free memory. At this point I'd sacrifice RAID 1 for better performance.
Should I got with the Quad Core Xeon with 4GB RAM for this webserver/database server config or go with 2 Core2Duo servers with 2GB RAM each?
Dual Opteron 252 Or Core2duo E6400
May 3, 2007Which one do you prefer?
- dual opteron 252 / 2GB RAM DDR / 15K rpm SCSI disk
- core2duo E6400 / 2GB RAM DDR2 / raid-1 sata (raid-edition) disks
It will be used for a big vBulletin forum. Price is around $200 different, core2duo a bit more expensive.
Is Core2Duo E8400 An Upgrade Over Dual Opteron 285
Apr 20, 2009I've had a dual Opteron 285 (dual core 2.6ghz) server with Layered Tech for the last couple of years, and I have a nice offer for a Core2Duo e8400 machine.
Currently my sites generates an average of one thousand simultaneous connections -- will the Core2Duo 8400 be more responsive than the two Opterons 285?

Best Option? Dual Xeon 2.4 / Xeon 3075 / Core2Duo E6750 / Quad Core X3210
May 9, 2008I'm thinking in changing my actual dedicated server, but I'm not sure if I will win with the change.
I use it for web hosting, but I am going to need a lot of Mysql use.
I also want to work with Flash Media Server or Red5, but I have the project stopped.
All are almost in the same price. What do you recommend me?
I have never touched Linux and my Server is Windows 2003, do you recommend me to change to Linux?

I see no sysctl settings or anything of that nature for it.

Server Cache
Oct 1, 2009I have reseller account from small web service company.
they are great and better than the famous company.
but I have one problem. I have personal blog, some time I don't see the new comment, also my visitor see the comment before 4 days ago only.
and there is vb forum, some times new member can't login and only you see the old topic, and some times you see everything ok and up to date.
me and all my visitor have the same problem and that can't be from internet service provider because they are from several country.
I had such problem before 4 years and it was because server Cache.
I didn't name the company because they are great and I don't want to blame them before I know certainly what cause the problem.

View 1 Replies View RelatedPHP And Cache-Control
Jan 27, 2008I seem to have the opposite problem of what most people complain about... I'm using some custom-built PHP scripts, the output of which is not getting cached. I want the output cached, because it doesn't change often.
If it's relevant, I'm using ob_start() to serve up a GZIP-compressed page.
I start off with a header("Cache-Control: maxage=3600, must-revalidate"). Yes, it's first, and yes, it's showing up properly in the browser.
However, requesting the page again returns an HTTP 200, not the 304 I'm expecting. It's pulling down the whole page again. It's not changing in between requests, and I'm simply visiting the URL again, not hitting Refresh. (Although it really shouldn't matter.)
Mysql Cache On A Vps
Apr 22, 2007[url]
has an article on mysql query cache.
It notes that in the mysql config file, having
query-cache-type = 1
sets the mysql query cache.
In mysql I note that
SHOW VARIABLES LIKE '%query_cache%';
outputs
+-------------------+---------+
| Variable_name | Value |
+-------------------+---------+
| have_query_cache | YES |
which indicates that cache is set, but...
find . -name "my.cnf"
./usr/local/cpanel/whostmgr/my.cnf
./etc/my.cnf
shows only these
set-variable = max_connections=500
safe-show-database
So where has query cache been set?
At the server level?
If so, am I able to set the query_cache_size and if so, which path?
Anyone have any comments on their mysql optimization on a VPS?
DNS/Proxy Cache
Jul 15, 2007I made changes in httpd.conf to redirect website to another website; after 15min I removed redirect but until now when client request website they are redirecting.
I'm sure I remove redirect.
we are locating in UAE, UAE has transparent proxy for all Internet connections so I think the problem in proxy cache, How i can confirm it? then can I avoid it ?
also when I put dot "." at the end of link site working without redirect otherwise it's not working.

Getting Around A Corporate Proxy Cache
Oct 7, 2009I'm assuming a corporate proxy cache is what they have set up. I have a client and every time I send them changes to a temporary page I'm hosting for review they can't see it.
They can hit refresh over and over but never see the new updates unless I change the name of the folder its in.
This is very annoying and it only happens with them and one other corporate client i have. They check on multiple computers and it will never refresh and load the new changes. I think this is their network cache that their IT dept. set up.
How can I get around this? I tried an htaccess trick I looked up for expiring files but it didnt work.
These files are on a shared hosting of mine on an Apache server.

Eventually, the cache reaches 2600000 and i would like to keep the cache smaller so that the free RAM is always steady around 500k for when a lot of traffic comes through.
is there a way to clear the old cache out faster?

A Few Words About DNS Cache Poisoning

Sda: For Cache Data Failed
Aug 11, 2007We just upgraded our server with 8 brand new seagate cheetah 15k.5's, a battery backup unit, and a 256mb dimm for the raid controller. In the boot process, i noticed an error about caching or something.
After analyzing the dmesg log, i found the error:
sda: asking for cache data failed
sda: assuming drive cache: write through
It seems like the kernel can't get to the raid controllers cache, so it switches to the write through setting.
I've benchmarked the harddisks with the write through, and write back setting. The odd thing is that both settings deliver the same performance.
Normally, write back increases the performance with like 100%... That's why we bought the battery backup unit.
So something is going wrong, but where lays the problem?

Dispatch.fcgi Kept In Cache
May 21, 2007I have Django (python framework) on a server, and I have a little problem. The application is kept in cache by FastCGI
When you make changes to your application you have to restart it. Touching the file doesn't solve my problem. The only solution I have is renaming the .fcgi file always, and if you use an orifinal file name, it actually works like before, prooving it's kept in cache.
What would you do? A cron job to remove these files maybe?

Cache The Dynamic Url (images)
Oct 3, 2007I've got an application (java web ) tha dynamically creats images ( with dynamic url - ...tab&vi=nia&h=24&ds=bottom&fn...) - like thumbnails,icons ect.
The think I'm trying to deal with is to force caching theese images by a browser.
When the application starts the server gets images and shows code 200 ( and this images apppers in web browser cache), but after reloding or simply viewing the images from the cache url the server shows again code 200. I'd like to have code 304 - not modified - like when browser gets an image from cache.
The dynamic url for image is being created only once - when the appication starts, and after that it stays unchanged, but I still can't force use the cached images - like when it is a static url - .../image.jpg.

Which cache-accelerator would you suggest for php-mysql apache?
View 3 Replies View RelatedWhen To Add More Ram. Swap/Cache/Buffer
May 23, 2007When is a good time to add more ram?
Since I got my server its ran with 1gb ram and has kept a free of at least 400mb since that time.
Now withing a few hours all of it is being kept in buffer/cache as the past week an showing about 15mb free (not counting buffer/cache) and has started in on the disk swap of about 400Kb.
So should I upgrade to 2gb now or wait till it goes deeper into the swap, and if so how far into the swap before you'd upgrade?
