ESXi and 1s on a virtual machine?

Question

VMware

This is the problem - deployed a network on VMWare ESXi 6.5.
Raised the virtual machine, Win, installed MSSQL, deployed 1s and sat down in thought.
It slows down wildly for 1s, especially when reading (reports, etc.)

Nvme disks, the declared speed should be enough, I test the write / read speed in a deployed virtual machine - everything is ok. Processor, RAM not loaded. I am testing the Gilev test itself 1s - and I observe a small number. parrots. And I just do not understand where to dig.

Answer 1

First, check that you have a Datastore disk partition and that the inside of the VM is properly partitioned.
Walk about "esxi disk alignment"
Well, and read the official docks "vsphere esxi vcenter server 67 monitoring performance guide" and "vsphere esxi vcenter server 67 performance best practices"
PS NVMe - probably a consumer?

Answer 2

IMHO, you shouldn't do that in production. We have a game in RTS, where the main resources are processor time, memory (taking into account the bus and timings) and Jops. Resources for the sequel - processor, memory, jops. Resources for the 1C application server are a processor (with one rhost-one core) and memory. Each application tries to get the maximum resources for its needs in a competitive environment.
Then the tax on virtualization is removed from this and "more gold is needed".…
In the simplest version (up to 50 users, but depending on the load), it makes sense to install the sequel and the application server on the same server, but without virtualization (what's the point of it if it's a specialized server). This will allow you to save a little on hardware and gain a little in speed due to shared memory. At high loads, the bandwidth of the memory bus may suddenly run out, the processor or disk queue may go into the shelf.
Therefore, with a large number of users, it is advisable to immediately plan a three-link. This gives some loss in Gilevsky parrots, but makes the system more predictable under load and easier to scale if necessary. At the same time, one more resource is added - network bandwidth (and latency parameter :)).

Answer 3

1. So I understand the car is home.
2. You need to enable virtualization in BIOS.
3. Raid completed? Raid 5 or 6. You need to enable the writeback cache. Otherwise, the recording speed is 15 meters per second.

Answer 4

As mentioned earlier - the characteristics of iron in the studio. I would not be so categorical about virtualization, of course there are drawdowns, but not twice. Let's say 27-30 parrots is the norm for simple servers. Are the power saving features disabled in the bios?

Answer 5

Try to select disk driver with Paravirtual SCSI base, disk mode Independent Persistent

Answer 6

Have you installed special drivers on the esxi server itself, and vmware tools in the virtual machine, bios are all fresh on the hardware and the rest of the firmware, and what kind of iron beast do you have?
