The driver takes 1900 nanoseconds to initialize, What waste of time!

it's actually 1,900,000 nanoseconds or 1900 microseconds.

ha, tell me more about big o notation and algorithmic complexity if I optimize simply by changing a timeout constant!

the ENA driver initialization time dropped from 173 milliseconds to a mere 1.9 milliseconds

The driver takes 1900000 nanoseconds to initialize, What waste of time!

Phoronix: Simple Patch Lets Amazon's EC2 Linux Network Driver Start ~90x Faster

With how ubiquitous the Amazon Elastic Compute Cloud (EC2) is, one may have assumed that for years the software stack was already extensively optimized to insane levels, especially as it concerns the boot time for being able to quickly respond to changes in load... But it turns out there still is some low hanging fruit such as with Amazon's "ENA" network driver and a new patch allowing it to initialize 90 times quicker...
