Remote Users complaining of Lag and speed issues

Hello,

I have remote users who complain of slowness\speed issues while connecting remotely. I would like to upgrade their services to have better connectivity but want to make sure I am investing in the right areas. Here is what they currently have.

Headquarters has a VMware RDS Session Host for these users to connect to Approx 12 users.
The remote site comes in via a WAN connection.

I am not sure if you need more info, but I am exploring options such as REMOTEAPP, VDI, or a better direct connection...

Any thoughts and ideas would be welcome.

VMware Horizon View would give a much better user experience, than RDP, because it uses PCoIP.

Before you look at swapping the environment, let's look at the config a bit, we have a similar setup for 250 users, but I will need some additional info.

1. What is the bandwidth on both ends?
2. What applications are in use
3. What are specs of the server?

Ok, we have 25 users haha... Here are your answers

1. Both ends the bandwidth appears to be really good. average: 70down\60up
2. Office suite, Sybase DB, Internet, Word processing. Internet usage, chrome, IE,
3. See attached from VCenter

and this is RDP ?

yes

is this a new implementation, or have the users always complained ?

and is this 25 users (concurrent) on a single server ?

what if you split the server, into 10 users per server ?

I would say that in a given time period, there are no more than 10 on this specific system.

From your experience, how are my resources for a RDS Session host. ?

16GB could be low....BUT...

how many vCPUs ?

what is the datastore ? how many disks ? RAID type, disk type ?

Interface I hope it's VMXNET3 and NOT E1000!

VMware Tools installed...

has it always been slow?

do you reboot the server every 24 hours ?

Bryant Schaper

I would be curious about the CPU as well, along with storage?

But I don't see a memory issue.

Do they complain about specific apps being slow, and any recent changes?

Vcpu info attached

Storage is RAID 10 SAN

so at first blush, and Andrew certainly is far better than me for VMWare, I notice you are trying to use 6 cpus. Which I would way is a lot, and depending on whatever else is on the system, you may be doing more harm than good. Do you see cpu wait times under the performance metrix?

Basically VMWare waits for 6 cpus to be available the execute the vm's operations, and if 6 are not ready, then the server waits, until they are. If you have a bunch of other servers on the system they maybe causing a high not ready/wait time.

Thanks for this information, I just reconfigured to use 4 processors and I will monitor throughout the day tomorrow.... , but in the process, I noticed the network configuration. Now unsure if I am utilizing all of the ports and the network on this host properly.

Your not, but this needs a different question to address this.

are you using VMXNET3 interface ?

VMNET3 is in use. When I go onsite I have to check the physical connections and then I will address the network issues.

Thanks for your feedback with this question. I am going to close this.
