We take a multi-step approach to diagnosing performance issues. While your VPS should generally remain fast and stable, some factors — particularly your workload and network routing — can cause temporary slowdowns.
There are two key areas to check:
1️⃣ Compute Resources (CPU & RAM usage)
2️⃣ Network Performance (connection quality and routing)
Step 1: Check Compute Resources
The first thing to do is open Task Manager on your VPS.
Look at your CPU and Memory (RAM) usage:
Is it spiking to 90–100%?
Or stable around 15–25%?
If your CPU or RAM are maxed out, it’s expected behavior for the system to slow down — applications may lag, charts can freeze, and typing or mouse inputs may feel delayed.
Why This Matters
Efficient CPU management is crucial for traders, especially during high-volume market activity. When CPU usage spikes, even for a few seconds, it can delay order execution or cause charts to freeze — meaning your trades reach the exchange slower. Keeping your resource usage balanced ensures smoother real-time responsiveness and minimizes risk during volatile conditions.
Try This
Close all running applications.
Reopen your trading platform (e.g., NinjaTrader, TradeStation, MultiCharts, Quantower, Sierra Chart, MetaTrader, IBKR) with a clean workspace — no indicators, no strategies, and one simple chart.
Check whether performance improves.
If it does, the issue is likely tied to your workspace or chart configuration.
Step 2: Remove Potentially Faulty Workspaces (NinjaTrader Example)
Sometimes, a corrupted workspace can cause freezing or slow performance.
To reset:
Close all applications (including NinjaTrader if open).
Open your Documents folder → NinjaTrader 8 folder.
Open the workspaces folder.
Move all .xml files inside (e.g., Untitled1.xml, MyStrategy.xml) to a temporary folder on your desktop — or rename the “workspaces” folder to workspaces OLD.
Relaunch NinjaTrader 8.
This will load NinjaTrader with a fresh, blank workspace.
Step 3: Check Network Performance
If your CPU and RAM look normal, but your mouse clicks lag or typing feels delayed, the slowdown may be network-related — meaning the VPS itself is fast, but your remote viewing stream is degraded.
Network Troubleshooting Steps
1️⃣ When did the issue start?
If it began recently, it may be a temporary routing issue between your ISP and the data center.
Wait a short while — these often resolve automatically once your DNS re-propagates.
2️⃣ Test your local internet speed
Visit speedtest.net from your local device (not inside the VPS).
Check your upload speed — it should be at least 50–75 Mbps.
If it’s lower, try from another connection.
3️⃣ Try a different connection
Use a mobile hotspot or a different high-speed internet connection.
If performance improves, the issue is with your ISP routing.
4️⃣ Try Parsec for improved remote streaming
Parsec uses optimized streaming technology that can outperform native RDP for certain clients.

Summary
If CPU/RAM are high → consider optimizing your workspace or upgrading your plan (e.g., VPS Lite → VPS Pro).
If CPU/RAM are low but performance feels laggy → it’s likely network-related, not the VPS itself.
Additional Notes
Over time, system factors like Windows updates, cached files, and third-party plugins can impact performance.
To maintain optimal responsiveness:
Clear your system cache regularly.
Avoid running large updates or downloads during trading hours.
Disable unnecessary background software.
If you’re running intensive platforms or automated strategies, consider upgrading to a higher-tier VPS or a dedicated server for maximum consistency and low latency.
