Ensure peak VM performance by: 1) Real-time monitoring: CPU, memory, storage I/O, network. 2) Alert thresholds: 90% CPU, 95% memory, 5ms latency. 3) Dynamic resource adjustments: CPU, RAM, storage. 4) Bottleneck analysis via dashboards. 5) Hypervisor optimization. 6) Load balancing. 7) VM right-sizing. 8) Capacity planning. 9) Automation & driver updates. 10) High availability/DR.

conseils pour améliorer leurs performances : 1.Vérifiez les ressources de votre système h?te : suffisamment de CPU, de mémoire (RAM) et d’espace disque. 2.Allouez plus de mémoire et de CPU : Augmentez la quantité de RAM et le nombre de c?urs de CPU Cela peut améliorer considérablement leurs performances. 3. Lors de la création de vos machines virtuelles, Les disques de taille fixe sont plus rapides car ils évitent la fragmentation. 4.Les logiciels VMware Tools, VirtualBox incluent des pilotes spéciaux qui améliorent les performances 5. Optimisez les paramètres vidéo : 6. Utilisez un disque SSD : offrent des vitesses de lecture et d’écriture beaucoup plus rapides. 7. Excluez les répertoires de machines virtuelles de votre antivirus.

The underlying performance issues for slow VMs can be attributed to the workload type. As a result we work backwards to review CPU (importantly wait time), Memory (usage vs allocation) and I/O stats (wait time, queue, latency) etc. 85% of the problems can be identified very quickly by reviewing these stats and some tweaks can provide peak performance. It also depends on how much spare resource capacity exists to allow for any changes.

Restart the server, services, end multiple open concurrent connections... Start there. Run updates, check what processes are running / lagging the system and network..

If my VMs are slowing down I'll: - Check esxtop or vSphere Performance Charts to find the issue (CPU, memory, storage, or network). - If CPU is maxed out, reduce vCPU overcommitment, align NUMA, and set reservations. - If memory is the problem, make sure there is enough RAM, remove unnecessary limits, and check for swapping. - If storage is slow, move critical VMs to SSDs, switch to thick provisioning, and manage queue depths. - If the network is slow, use VMXNET3 adapters, enable jumbo frames if needed, and adjust traffic shaping. - Make sure DRS is balancing workloads properly. - Keep VMware Tools and drivers updated. - Monitor performance regularly to confirm the issue is resolved.
