Interesting. Recommendations: Change the name. Enough said. Include a restore script as part of the tool, yes there are other ways to do it manually but it is very important to anyone taking a backup that it is restorable. There is no guarantee that external scripts wont break (e.g changes in...

APC was pulled from 5.5 since Zend Opcache is built in (which should eventually give better performance). APC development has stalled, but for pre 5.5 it is the best of the caches in my opinion. APCu carries on the APC api (think user caching) for php5.5, Zend Opcache does the opcode caching...

I don't really have a timeframe for total development. Its still "under development" in many ways (its not 1:1 with WHMCS, the functionality we need works). Its integrated with our service panel, so even if I knew how long the original release took (2 developers for roughly 3-6mo I think) it...

Maybe thats that then, suPHP is so far below everything else that it probably falls under "a". Its also worth noting that  took a quick look at the configs used between all tests and they are hardly equal. Now I dont know what concurrency mode is used for the test, it isnt mentioned but the...

I am aware of LSAPI, its been around since the days that I used to run LSWS on one of my side projects (pre nginx). Yes its faster than php5-fpm in most circumstances but its marginal compared to the processing cost of php. Taking data from fastcgi / LSAPI -> HTTP is a really very small part of...

The usual ratio of CPU usage used in webserving to the CPU used in rendering and processing for a page in PHP is atleast 1:10 (usually much more depending on the complexity and quality of the application). PHP has to do alot more work (parse, connect to mysql, generate a page, include files...

Unless that customer was just serving static files (a rare use case) I dont think that graph is correct, PHP / your dynamic web language of choice should be a very large (and constant) part of that graph. Unless something was changed in the process (e.g opcode caching) I would suspect a mistake...

Seems like a Micro optimization to me, since Linux will by default cache file's with the free portion of your ram. Unless he is referring to using a ramdisk (tmpfs) for short term writes (e.g php sessions).

I am not even going to bother.

There is absolutely no reason you would want to save opcode to disk, memory is MUCH faster. Saving and loading from disk would negate most of the performance APC will give you. APC provides a cache of the exact amount of memory you configure it for, it does not "hog memory".  The whole point of...

Clustering is what I would do instead of one big server. That aside, php5-fpm + APC (with .stat turned off if possible) + nginx + srcache + redis is pretty amazing, basically you hit the memory bandwidth limit on most sites before CPU or disk.

As someone who wrote my own billing panel (due to deficiencies in WHMCS) I can tell you, its not easy. And its not enjoyable development unlike working on a VPS Panel etc. It would be even harder to develop it for a wider audience, different taxation systems and requirements for record keeping...

Damn,  14Mbit/750Kbit here TPG Unmetered. Would kill for NBN, even have a router with dual wan ready for it :)

I would look up some of the ones in my media server if the raid5 controller supported SMART. Some of them are from the first generation of WD Elements externals. Easily 2005-2006 and going strong. WD Greens aren't that bad :P

Unfortunately sequential attacks are getting more and more common, until a few months ago we were aware of two such incidents. Now I've seen three this month. Unfortunately for providers like Ramnode there is little that can be done with these attacks other than nullrouting the affected IP...

Scalability 1.2 - Zabbix 2.2 packages. Just a quick update as per a request with a copy of the pre-release Debian (Wheezy) packages I am using. I would not advocate using them in production etc. Majority of the credit goes to Dotdeb. It is Based off the dotdeb Zabbix 2.0.9 package template, all...

I like both, but not either. In-Progress first reply - "We are aware of and acknowledge the issue.... Please hold for some minutes while we investigate and resolve." This statement can be mostly pre-canned, emphasis should be placed on informing the client that they arent just sitting in a...

Scalability 1.1 - More information. Some interesting tweaks discovered over the past week. MariaDB If you are running Zabbix in production, you likely have many excess processes to handle cascading failures. If you are anything like us you probably have in excess of 200 Zabbix processes with...

I got to stop getting distracted....   Actions? Media? Media - A method of executing of sending a message. e.g SMS, Email or custom script. It is in this section you also define configuration such as the email address to send the email from and the SMTP server to use. This section is found under...
