Please help me reduce TTFB of my website (magento) which is running on VPS Dedicated Hosting with CentOS release 6.6 (Final). Current Time To First Byte is: 19.427 seconds Just caches don't improve performance, they reduce hardware utilization for repeated requests. While implementing the Will Farrell's other suggestions, you need to identify those parts of Magento code that are slow. For that, you will need to enable Magento Profiler – the built in Magento tool that lets you see what Magento is doing and on what it spends most of the page load time. here is the details method how to enable

I've an unusual problem that's causing me to tear my hair out. I have a Netty Client/Server setup. The server sends a command object to the client. The client then sends each of the binary commands found in the command object to a device attached to it's local serial port. The answers to each command ( a binary string) is stored within the command object and when all the commands have been executed, the command object is returned to the server. So I'm using the ObjectEncoder and ObjectDecoder in both my client and Server pipelines. I have one specific, repeatable case where the server throws

We're running CentOS 6 and PHP 5.3.8 (as an apache module) which should have JSON as part of it's core (I'm told). Looking at # php -i on the command line I can see under Configure Command '--enable-json=shared' ... great! However, looking at php_info() on a web page Configure Command shows '--disable-json' . No problem I thought, I'll just install it using pecl: # yum update php # yum install php-pear # yum install gcc # pecl install json # service httpd restart Success, that aught to do it I thought. However php -m shows: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib64

I am trying to set up a git repository over my Apache 2.2 on a CentOS 6 box, with git installed. I have tried following many different directions, and I am at a loss. My current situation comprises of being able to clone normally, but being completely unable to push. It seems as though I am incapable of getting the authentication bit to work properly, as I can normally perform the push while setting http.receivepack to true . I have installed AuthzUnixGroup as well as mod_authz_external . I went to /var/www/git and created a repo named my-repo.git and did a git init --bare inside it. Then I

前言： 163的源速度快（ http://my.oschina.net/chocoball/blog/204249 ） ，但有的包不一定有。比如，没有比如。EPEL源用过之后都说很爽！ 一、什么是EPEL 如果既想获得 RHEL 的高质量、高性能、高可靠性，又需要方便易用(关键是免费)的软件包更新功能，那么 Fedora Project 推出的 EPEL(Extra Packages for Enterprise Linux)正好适合你。EPEL(http://fedoraproject.org/wiki/EPEL) 是由 Fedora 社区打造，为 RHEL 及衍生发行版如 CentOS、Scientific Linux 等提供高质量软件包的项目。 二、EPEL源使用感受 1、不用去换原来yum源，安装后会产生新repo 2、epel会有很多源地址，如果一个下不到，会去另外一个下 三、 CentOS 6.x X86_64 安装EPEL 源 第一步下载需要的RPM文件 wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpmsudo rpm -Uvh

I recently started setting some thread names within my application by using pthread_setname_np(). After doing this, if a crash occurs within one of the named threads, the core dump filename is getting the thread name instead of executable name with core_pattern %e.%p.core According to the core man page , the %e flag in the core_pattern is supposed to get expanded to the executable name. It doesn't say anything about the thread name. I want the executable name and not the thread name, because I have other automated scripts (not maintained by me) that depend on the core filenames beginning with

I'm now deploying on CentOS 6.5, and I'm now starting to use docker. So, I follow the instructions on: https://docs.docker.com/engine/installation/centos/ No matter which method I follow to install, I get version of 1.7.1 .
