WAN not very fast speed

[caradou]

Hello team,

I have a very strange issue.

a fresh install of opnsense16.7.2 into a VM on a ESXi 5.5
2 network cards (vmxnet3) ; one for wan and another one for Lan

When the opnsense juste boot, and i curl, i have

Code: [Select]

curl http://ovh.net/files/10Gio.dat >/dev/null
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  7 10.0G    7  730M    0     0   111M      0  0:01:31  0:00:06  0:01:25  111M
So a very good speed (111M)

But after about 5 minute, the same give me

Code: [Select]

curl http://ovh.net/files/10Gio.dat > /dev/null
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  2 10.0G    2  245M    0     0  6815k      0  0:25:38  0:00:36  0:25:02 5939k
A very poor speed 5939k

Nothing changed. No machine connected to the Lan interface (i have disconnected the lan, and have the same issue)

Trying to disable CRC TSO and LRO, no effect.

If i try to download from another VM into the same ESXi, i have a good speed.


Any help ?

Thank you

Hello,

Do you have installed the package "VMware tools wrapper" inside your OPNsense ?

For the moment I have an 16.7.1 on ESXi 6.0 and it's fine, it match my WAN speed (>30 Mbps)

What dashboard of OPNsense say about resources usage ? And VMware Perfomance tab?

[caradou]

Helo echappatte,

Yes i have already install it from the firmware tab

Code: [Select]

os-vmware 1.3 299B VMware tools wrapper
About the resources, all is fine. Load less than 0.10, and all other less than 10%

There is any vmware tab on opnsense?

Regards

@echappatte,

Your nic card are on e1000 or vmxnet3 ?

[echappatte]

Hello caradou,

I use VMXNET3 for all my interface. All my net are on a separte vNIC, as VMXNET 3 does not allow multiple VLAN IIRC (e1000 do this fine).

When I ask about VMware performance tab, it is under vCenter or ESXi, not related to OPNsense.

[caradou]

Thank you for your answer. On Vcenter nothing, the performance are very good, and the resource usage very poor.

You welcome. 

I just installed the 16.7.2 and tested immediately after, no problem.
Tested again later, still the same speed of 30Mbps DSL connection.

If you make test without CURL, just from lan to wan, do you have the same problem ?
