why are azure vms so slow?

The first limitation might be coming from your virtual machine. Each type has its own total IOPS limit. Thus by adding more disk or faster disk than the type and size allows will not make any speed difference in the end. One of the obvious reasons for faster disk performance is to use SSD disks instead of HDD.

All some time, the process suffers from network latency and SMB server latency. This is because the SMB request is first translated to a file system command and then to the actual file system latency to complete the operation. If any antivirus program is running, the transfer slows down even more.

Azure managed disks are block-level storage volumes that are managed by Azure and used with Azure Virtual Machines. Managed disks are like a physical disk in an on-premises server but virtualized. With managed disks, all you have to do is specify the disk size, the disk type, and provision the disk.

Causes of slow access times for NFS. If access to remote files seems unusually slow, ensure that access time is not being inhibited by a runaway daemon, a bad tty line, or a similar problem. Use the nfsstat command to gather information about your network connections. To set MTU size, use the SMIT fast path, smit chif ...

There's all sorts of reasons it could be "slow", but as it's a new installation, it's quite likely that... With an empty Jira, we can rule out dodgy configuration, users thrashing it, too much data, etc. Start with the virus checker - if you have one, turn it off and see if things improve.

Even though Hyper-V runs as a Windows Server role, it is still considered to be a bare metal, native hypervisor. ... This allows Hyper-V virtual machines to communicate directly with the server hardware, allowing virtual machines to perform far better than a Type 2 hypervisor would allow.

There are many excellent reasons to use Microsoft Azure to host applications and enterprise systems. There's even plenty of criticisms on it being expensive to host small websites, however the App Service offering in Microsoft Azure does offer the ability to easily host a website in the cloud completely FREE!

What else causes slow upload speeds? Aside from your ISP's infrastructure, the hardware you're using could be creating a bit of an upload lag. You might have an older modem or router that could use an upgrade. Your ISP should be able to help you figure that out.

Lastly, the service is priced quite provocatively. If you wanted to setup your own virtual machines in Azure that are domain controllers that replicate back to your datacenter, the cost would be over $450 a month. This is the cost for 2 virtual machines and the VPN connection.

In VMWare is does not make a difference. It is purely based on how the cpu's are presented to the guest. Whether you choose dual sockets single core each, or single socket with dual core, VMWare treats those as the same, you get 2 cores of CPU time.

On environments with only one Active Directory (AD) server (domain controller), a change usually takes up to ~5 minutes to get processed and sent to the cloud, barring any issues in regards around network latency, processing and also the size of the organization being synchronized.

The lightweight nature of containers—and their shared operating system (OS)—makes them very easy to move across multiple environments. VMs are typically measured by the gigabyte. They usually contain their own OS, allowing them to perform multiple resource-intensive functions at once.

When provisioning Azure Web Apps (Azure App Services), a pool of IP addresses are allocated to the underlying scale unit of the web app and from what I have found the outbound IP addresses wont change if you stop/start the site or change to a different app service hosting plan (at least in my testing).

Transcript: More virtual CPUs are assigned to the virtual machine than the number of physical CPUs on the host system. This is likely to degrade performance of your virtual machine.

If you want to measure performance, you need to do so in the native OS. You will find the NTFS filesystem is much faster in Windows than in Linux. In much the same way as EXT4 is much slower in Windows than in Linux.
