To optimize the performance of virtual machines running sluggishly across different OS, take the following measures: Resource Allocation: Ensure VMs have sufficient CPU, RAM, and disk space based on their workload. Virtualization Settings: Adjust hypervisor settings for better resource management and enable hardware acceleration. Guest OS Optimization: Tune OS settings (e.g., disabling unnecessary services or features) for better performance. Storage Optimization: Use SSD storage or implement thin provisioning to speed up I/O operations. Monitoring: Implement performance monitoring tools to identify bottlenecks and resource shortages.

Se antes funcionava bem e começou a ter um comportamento de lentidão, o primeiro passo é investigar, antes de sair alterando alguma coisa é bom monitorar e analisar possíveis gargalos. Caso você tenha criado as VMS e uma se apresentou mais lenta, pode tomar algumas ações, como verificar os Recursos de Hardware da VM, Desabilitar serviços e processos desnecessários do SO da VM, verifique Atualização de drivers e ferramentas de virtualização. Se possível, mova as VMs para discos SSD em vez de HDDs para obter tempos de leitura e gravação mais rápidos.

It depends what underlying architecture are you using, is it cloud or on-prem (vmware etc). Since the statement states that the VM are running sluggishly across different OS so either it could be: 1) host thats running these VMs have a performance bottleneck 2) a particular region/zone in case of cloud is experiencing some performance issues If its the host , try moving it to another host either redeploy in case of azure cloud or live migrate the VM to other host in case if VMware If it’s a region/zone that has been impacted try moving the apps to secondary site.

To optimize sluggish VMs: 1. Allocate Resources: Ensure sufficient CPU, RAM, and storage; avoid over-provisioning. 2. Disk Performance: Use SSDs, thin provisioning, and defragment disks. 3. Network: Optimize NICs (e.g., VMXNET3), prevent network saturation, and enable offload features. 4. Guest OS Tuning: Disable unnecessary services, update OS/drivers, and install VMware Tools/Hyper-V Integration Services. 5. Hypervisor Settings: Adjust resource scheduling, enable NUMA, and keep the hypervisor updated. 6. Monitor Usage: Use performance monitoring tools to adjust resources based on demand. 7. Templates: Use optimized templates for consistent VM performance. These steps will improve VM performance.

Check if the VMs are in the same host. If it is, migrate the VMs to another host then check the problematic host to find the root cause. If using VMWare make sure vmotion is enable to let the host migrate the VMs to even out the resources across the hosts in the cluster automatically.

If using mechanical drives for a datastore, consider also using a ssd cache if its not possible to replace all the mechanical enterprise drives. synology rack stations for example have a cache feature built in and works great.

We can optimize the performance of virtual machines by adjusting the allocation of CPU, RAM, and prioritizing SSDs on the host; keeping drivers and systems updated, and disabling unnecessary services. Using fixed disks and optimized drivers (like VirtIO), reducing snapshots, and installing virtualization provider tools (e.g., Guest Additions). On the guest system, disable unnecessary services, optimize antivirus settings, and monitor resource bottlenecks with specific tools such as htop or hypervisor monitors. By taking these actions, Virtual Machines will undoubtedly improve in performance.

Virtual Machines (VMs) are powerful tools, but when performance lags, productivity suffers. In addition to allocating sufficient resources, keeping systems updated, and investing in SSDs, there are other strategies that can help: * Enable virtualization extensions: Hardware features like Intel VT-x or AMD-V can significantly boost performance. * Manage snapshots wisely: Excessive snapshots can strain storage and impact performance. * Tune hypervisor settings: Reducing graphical settings, adjusting CPU priorities, and leveraging paravirtualization can make a big difference. * Monitor workload usage: Monitoring tools can help identify real-time bottlenecks.

Para cada sistema operacional, existem drivers específicos para a versão do virtualizador. Verifique se os drivers estão instalados e atualizados no host que apresenta lentidão.

Interesting subject! When we talk about performance, we need to understand the context in which we find ourselves! There are many ways to improve performance at every level, from hardware (hp conrep bios, proc affinity, numa affinity) to applications (os powercfg, ndis, nic proc affinity, polling mode, registry settings ect. ) and even networks! Numerous fine-tuning options are available to meet different end-user needs.
