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.
