VSphere / ESXi 6.5 AHCI performance problems with native driver / FIX

Im having performance problems when using the new VMWare native AHCI-driver on several hosts (Intel Avoton and also Xeon 1225 V3 System (HP Ml310e gen8)).

Using SSDs on those systems - im not sure if it also affects HDDs.

Moving back to the legacy vmklinux AHCI-driver fixes the problems.

See this blog post:

NXHut - IT and Windows - News: Fix slow disk performance (vmw_ahci driver) in ESXi 6.5

I hope this gets fixed soon so I can move back to the native drivers Smiley Happy
