AVAILABLE HARDWARE 3 physical servers (node1-osd, node2-osd, node3-Ceph-client) , model HOST-32H -2x 2 TB SATA3 + 2 x480GB SSD (no hardware raid) -10Gbps private network OVH vrack - 1Cloud OVH VPS as monitor( for the moment OVH doesn’t support private networking between dedicated and cloud VPS. So, even is incorrect, for testing purposes, the ceph-monitor will be KVM on top of node2) NODE CONFIGURATION sda, sdb - 2X 480GB SSD, CentOS 7 sda1/sdb1 raid1 16G swap sda2/sdb2 raid1 1G /boot sda3/sdb3 raid1 300G / ( needed for libvirt OpenShift KVM’s) sda4/sdb4 noraid, no filesystem, OSD ( optimal size to be established) sda5/sdb5 noraid, no filesystem, journal disk ( optimal size to be established) sdc, sdd 2X2 TB SATA3 no raid, no partition, direct OSD ( separate cluster, for performance reasons, don’t want to mix ssd with sata) NOT INCLUDED IN THIS JOB -Openshift nodes will be setup later as KVM’s ( on top of node2/3). For testing purposes, in this job we shall setup ceph client with docker installation on KVM1 and also on node3-ceph-client, bare metal. -Additional nodes will be added later. After more than 5 -10 node, we consider switching to OpenStack, settings up OpenShift on top of it. So, for the moment, we exclude OpenStack, for maintenance burden and performance penalty. by including another layer. JOB DESCRIPTION -Validate current startup architecture. Details: recommends “You may use a virtual machine for your ceph-client node, but do not execute the following procedures on the same physical node as your Ceph Storage Cluster nodes (unless you use a VM).” In this respect, I can’t setup Openshift nodes directly on bare metal ( needs KVM on top of node2/node3) , because Kubernetes persistent volume rbd client could conflict with ceph server libraries. After architecture validation, I shall do myself the basic setup of the servers and -Setup ceph clusters - Test high availability ( shutdown node1... Afterwards, OSD node2, ceph-mon KVM on node2 and node3-ceph-client should continue serving the testing web app) -Performance analysis of the OVH setup OHV built-in OS installer, with custom kernel, performs network transfer with 589.9MB/s, but doesn’t have KVM, Ceph included. Centos 7 installation from USB iso performs network transfer only with 294.9MB/s Our workaround was to use OVH default installer and then to replace their custom kernel with Centos7 stock kernel, obtaining speeds of 589.9MB/s. It would be nice to identify the OVH installer optimization tricks. -Benchmark web application (vanilla drupal install) ( setup block devices for web files on SATA drives, and mysql on SSD drives) -Performance tuning & benchmark ceph tools - Workflow via Skype share screen with voice ( chat only is excluded) , root access with screen -rx ,with static ip firewall. Thank you!

We have a lot of optimization efforts already in place. However, we're seeking a major improvement to what we have now. We're not looking for someone to simply configure a popular cache plugin. We know how to do that and already have. We're well past that point. We need an expert who's confident they can significantly improve the speed and performance of a wordpress driven site that has a lot of plugins (58 active). Currently, here is the environment: We have 4 performance tools running. 1. There's a server level Apache process running on on WHM called NGINX. 2. WP cache plugin called WP Fastest Cache (Pro version) for browser cache, zip compression, CSS/JS optimization, etc... 3. CDN for off-site hosting of images. We're using Jetpack for this. 4. A plugin called "Plugin Logic" that handles allows granular control over which plugins files are loaded on which page. This above all else has given us the most speed boost. However, as you'll see it's heavily configured to make it work. We are open to changes in the software employed if confident it will deliver improvements. With those site wide tools covered, here are two areas acting especially sluggish we would like to see big improvement too. Optimizing FacetWP. After #4 was setup, average page load times greatly improved. The two search pages titled "Jobline" and "Showcase" on the main menu contain a Ajax driven faceted search plugin called "Facetwp". This plugin is very important to the site model but it seems to be exempt from any form of cache optimization I've thrown at it. You will notice that the basic page elements actually load very fast, but the search elements take much longer. Homepage w/ video We have a long homepage and no fat to trim at this point. It holds a HD vimeo video that's especially cumbersome. It currently takes 4-8 seconds to load on average. We'd like to improve this. Backend The plugin "Plugin Logic" while very good at selectively loading plugins on the front end, doesn't help us on the backend. It's very slow in the backend. We'd like this improved. If interested in the job, I will provide a link to the staging domain in private message. Please let me know what questions you have for me. Thanks.
