Cache Systems For Apache In Windows
Mar 27, 2009
I have a fair ammount of load on the server, and I want to cache as much as possible to reduce disk IO. The harddrive is a major bottleneck for performance. The server serve a lot of files larger than 10MB, so I want to cache as much of the files below 10mb as possible.
First off I want to cache around 200k thumbnail files, where around 1000 new gets added every day.
Secondly it would be preferred to cache dynamic files in a way that the file timestamp is checked at a regular interval, and then read again if timestamp has changed.
Is there any free solutions on windows with apache for this?

I 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.

I have Apache 2.4.6 on a Windows Server 2008 (windows build from apachelounge). I want to use it as reverse proxy cache with mod_cache_disk.
My configuration is:
Code:
<IfModule cache_module>
<IfModule cache_disk_module>
CacheRoot C:/temp/cache
CacheEnable disk /
CacheDirLevels 2
CacheDirLength 3
[Code] .....
Loading a page with ~150 files (most images and js files) i keep runing into "locked requests" that are not comeing back and block the whole page from finishing loading. The files differ every time.
I see this warnings in my error.log (looks like they are connected to the behauviour above).
Code:
[Tue Nov 19 20:38:10.890013 2013] [cache_disk:warn] [pid 216692:tid 15924] (OS 5)Access is denied. : [client x.x.x.x:58963] AH00699: rename tempfile to file failed: C:/temp/cache/aptmpcBQArf -> C:/temp/cache/H8Cta/9ha4U/Uhhhs/OlQfU/1Q.data,

We have a Joomla based website and we are using the inbuilt cache to make the website fast enough for our users... but it really isn't working well... i would say.
The Joomla Cache is very limited and we were thinking if we can enable a server side cache for apache/php or something like that... which would work above Joomla and make all the contents cacheble.

I have successfully installed eaccelerator on my win2k3 box and it is working great. The problem I am having is that every so often the cache files are mysteriously cleared. I know that the cache is cleared when apache is restarted but I have not restarted it and the files still go missing after a period of time. I have the ttl values for ea set to 0 to disable them.
Here is the ea ini in php.ini:
extension="eaccelerator.dll"
eaccelerator.shm_size="64"
eaccelerator.cache_dir="C:Cache"
eaccelerator.enable="1"
eaccelerator.optimizer="1"
eaccelerator.check_mtime="1"
eaccelerator.filter=""
eaccelerator.shm_max="0"
eaccelerator.shm_ttl="0"
eaccelerator.shm_prune_period="0"
eaccelerator.shm_only="0"
eaccelerator.compress="0"
eaccelerator.compress_level="9"
eaccelerator.allowed_admin_path = "D:WebsitesThe Family Garrisoncontrol.php"
I am running php as php-cgi.exe with MS fastcgi enabled on a 32bit system.

We are currently building out our new server room and are currently unsure which UPS system to purchase.
Does any one have any experience with either the APC Symmetra LX or Liebert Nfinity systems? We require ~8kva. Both units appear to be very similar in specs and both allow expandability.

We have an older CardKey system in place here and are looking to do some updates. Anyone know of distributors of Pegasus software to manage the systems? Dealing with Johnson directly has been a huge pain and they are never around when you need them. I am in the Dallas area just looking for contacts on managing the systems.

i know maybe it is wrong for this topic to be here, but i am going to focus on my question in technically .
my question is " how backorder systems work? " .
i dont want description of them, i know they check the domain over and over and register it as soon as be available.
what i mean is what system they do to check the availability of domain better ? public whois database's are caching and not return the realtime result.
so what they do ? do they contact directly to internic whois servers ? or they use "whois" linux command?
anybody know what they do to get realtime domain check?

I sharing File system using NFS between 2 mailservers running postfix on CentOS 5.2.The mail servers shares the base mail directory of virtual users e.g. /home/vmail.
It appears to run fine since last couple of months,just requires feedback if anybody already tried sharing mail directories between 2 or more mail servers.
Or is there any alternate solution for sharing data between servers?

I have had enough of email problems that constantly happen on a server. For about three weeks now I have been dealing with email issues that I am going out of my mind. Does anyone have a suggestion as to a email scheme that will work. Here is what I would like to do. Disable Exim COMPLETELY. Either setup a server for email only or find a email solution. Email will be pointed ONLY by way of DNS.Once I get email fixed on this box it works for a day and next thing you know it's all messed up again. Somehow etc/localdomains and etc/remotedomains either vanish or get over written plus a bunch of other things including permissions.All I know is this is getting ridiculous.I don't want any sort of email system on this box. I want all my email to go though DNS only to another server. We already have on service that we use for Exchange, so all the MX Records point to that server, but email still has to interact with this server first, which I don't want it to.

how you guys monitor your websites and how you are alerted to it going down?
I have a backup VPS which will monitor my main site, with DNSMadeEasy IP failover to the backup server. But I would like to know it just went down!
I have googled and cant find an email to pager system, so I am hoping there is a email to SMS system?

to ask about this offer (millenniumdata dot com/BUSINESS/Business-Default.asp?include=Business-Dedicated-Servers.asp) I found. They have live chat support so i talked with someone and what he did say me is: servers come with Fedora and whole LAMP environment installed, you can SSH to the server, and install VNC, you have full ADMIN rights to install anything you wish, servers are not managed (he said that they are Managed in the sense that they are monitoring PING POWER and PIPE), they can Re-image to default for free, no setup fee, month to month payment.
I didn't use any dedicated server, I only used shared hosting. What I planed is to move my OpenX (former names OpenAds and phpAdsNew) installation to this server for now to see who is that working. I think that server is capable to run it, since it is currently run on shared hosting.

I guess I have finally seen the adverse effects of raising the conntrack table max too high.
May 15 09:13:52 cp4 kernel: [6430723.486626] dst cache overflow

I got tons of these during an attack today. I have googled around for a lil while and not have been able to find any useful info on raising this cache level up. Would anyone here know how to do this?
I see no sysctl settings or anything of that nature for it.

I 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.

I 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.)

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?
