CentOS / Red Hat Enterprise Linux 5.2 Poor NFS Performance and Solution

A few days ago I noticed that NFS performance between a web server node and NFS server went down by 50%. NFS was optimized and the only thing was updated Red Hat kernel v5.2. I also noticed same trend on CentOS 5.2 64 bit edition.

NFS server crashed each and every time web server node tried to store a large file 20-100 MB each. Read performance was fine but write performance went to hell. Finally, I had to rollback the updates. Recently, while reading Red Hat site I came across the solution.

Updated kernel packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 5:

* a 50-75% drop in NFS server rewrite performance, compared to Red Hat
Enterprise Linux 4.6, has been resolved.

After upgrading kernel on both server and client my issue resolved:
# yum update

Linux / UNIX RT Project Management Ticketing System Tutorial

Internally we use RT (enterprise-grade ticketing system) for customer support and it is one of the best GPL software around. It enables a group of people to intelligently and efficiently manage tasks, issues, and requests submitted by a community of users. RT manages key tasks such as the identification, prioritization, assignment, resolution and notification required by enterprise-critical applications including project management, help desk, NOC ticketing, CRM and software development.

Linux magazine has published a nice article about RT installation and configuration:

Managing bugs and help requests isn't easy, but it's crucial for effective project management. Using the wrong tool can set your project back to the dark ages, but the right tool can help your team excel. With that in mind, let's look at Request Tracker, an enterprise-grade (and free software) ticketing system written in Perl.

A ticketing system is a piece of software in which every bug, request, or problem is entered as a 'ticket,' which can then be tracked. It can be allocated to someone to fix, given a priority, placed in a queue (to separate out different types of bug or request), commented on, replied to, and finally closed when resolved. The system can also send progress updates and reminders to the initial requester and to other people involved with the ticket. RT handles all of these functions and more.
