Help, slow and freezing ESXi 6.5 network

Environment :

DELL PowerEdge T330 server machine

https://downloads.dell.com/FOLDER04457723M/1/VMware-VMvisor-Installer-6.5.0.update01-5969303.x86_64-...

The server has a PERC S130 Controller, two 1TB SATA disks, two 100/1000 network cards, Lifecycle installation.

In PERC the raid is by software, the ESXi Free was installed as NOT raid without disk 0 using a network card 0 IP 192.168.0.201

Problem :

On disk 1 a STORAGE 500GB was created, a VM created on it, Windows Server 2003 SP1 32 bits occupying 50GB C disk and two other F and G disks in two 200GB partitions and VMware Tools with the drivers.

On disk F and G there are XBASE databases that demand a lot of disk access and the network of that VM server is very slow.

If the same database were on a physical machine then such a problem does not occur.

VMTools installs Intel drivers on the VM card instead of the actual board's Broadcom drivers. I do not know if it is possible to put the card 1 directly as a VM card or have the physical drivers recognized, it seems to be something related to this.

Some guidance please

Hello,

Need to run the ESXTOP command to see if there is any disk latency. For reference: Using esxtop to identify storage performance issues for ESX / ESXi (multiple versions) (1008205) | V...

actual board's Broadcom drivers

I am assuming it is Broadcom 5720. You might want to disable the NetQueue. Have a look at this KB https://kb.vmware.com/kb/2035701

Broadcom 5719/5720 NICs using tg3 driver become unresponsive and stop traffic in vSphere (2035701) |...

Even though the KB covers only ESXi 6.0, if the bug in the tg3 driver remain unfixed in ESXi 6.5, you could be experiencing the same problem.
