| Tuning Area | Action | Expected Gain | |-------------|--------|----------------| | | Set HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\ClearPageFileAtShutdown = 0 | Faster logoff/reboot | | CPU | Disable C-states in BIOS (for persistent VMs) | Lower latency, higher power cost | | Network | Enable EDT (Enlightened Data Transport) via HDX policy | 30-40% better throughput on high-latency | | Graphics | Use "Visual Quality – Medium" and "Use hardware encoding for video codec" | Reduce bandwidth by 50% |
As you plan your next Citrix deployment—whether on-premises, hybrid, or full-cloud—spend time on your golden image, document your VDA version and optimizations, and remember: every smooth Citrix session begins with a healthy, well-tuned Virtual Delivery Agent. citrix vda

But the true, unsung workhorse that translates every note into action is the Citrix Virtual Delivery Agent (VDA) . It is the software sentinel residing on every physical or virtual machine that delivers apps and desktops to the end user. | Tuning Area | Action | Expected Gain
