The most efficient way to Improve Linux Server Performance

Anonymous's picture

Install TrustLeap G-WAN: it's free.

It does the job with million times less servers than IIS 7.0 .Net C# (same story with Apache PHP or GlassFish Java).

Segmentation Offload

Anonymous's picture

thanks for this useful article.
I'm a linux user and I'm looking at the network device drivers.
I've seen a few NICs support the TCP segmentation offload (as HW function), UFO etc.
But I've not clear if the GSO (Generic Segmentation Offload) can actually improve the network performance.
What do you think about the GSO performance?
Many thanks.

PS: in the end is the GSO a sw support?

what was the tested configuration? what host MB/CPU/OS? how was the "dumb" nic configured? what's the nature of these "scripts" in the workload?

without mentioning any of these things, the article is mere marketing fluff, and quite disappointing for LJ.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
