vSphere 6.5 + native vmw-ahci module = slow performance?

[malefik]

Hello colleagues. We use:

- VCSA 6.5.0.21000

- a few ESXi, 6.5.0, 8935087

- vSAN all Flash

- RAID S3108L-H8iR

Now the module "vmw-ahci 1.1.1-1vmw.650.2.50.8294253" is activated in hosts. Does it have performance problems?

I read that earlier the module "vmw-ahci 1.0.0-32vmw.650.0.0.4564106" did not allow to get the maximum speed and I had to deactivate it by switching to sata-ahci...

Now this problem is urgent?

As per the below links, the issue has been addressed in the driver version 'vmw_ahci 1.0.0-37' that is bundled with ESXi 6.5 U1. You are already on a higher version -
