CDN & Speed Optimization

HEIMWALL serves traffic from edge servers, shielding your origin from attacks and load. Your origin IP address is never exposed to visitors or in DNS.

Speed optimizations are controlled by four independent toggles at Console → WAF → [your domain] → Speed. Each toggle takes effect immediately; there is no separate save button.

HTTP/3 (QUIC)

Modern browsers connect using the QUIC protocol over UDP port 443 instead of TCP. The connection setup completes in a single RTT; returning connections can use 0-RTT.

	HTTP/2 (TCP)	HTTP/3 (QUIC)
TCP handshake	1 RTT	—
TLS handshake	1 RTT	combined
HTTP request	1 RTT	0–1 RTT
Total (cold)	~3 RTT	~1 RTT

Approximately 60% shorter latency on cold connection setup — most noticeable on mobile and poor network conditions.

Older clients fall back to HTTP/2 or HTTP/1.1 automatically; no additional configuration is needed.

Note

HTTP/3 continues to work even when Development Mode on the Cache page is on. The three optimizations below are processed through the cache pipeline, so they are temporarily disabled while Development Mode is active.

Auto Minify

Removes unnecessary whitespace, line breaks, and comment characters from HTML, CSS, and JavaScript responses. Content behavior is unchanged.

# Before
<!doctype html>
<html>
  <body>
    <!-- hero section -->
    <div class="hero">
      <h1>Hello world</h1>
    </div>
  </body>
</html>

# After
<!doctype html><html><body><div class="hero"><h1>Hello world</h1></div></body></html>

Typical HTML pages see approximately 42% smaller responses (1.24 KB → 0.71 KB).

Image Optimization

Re-compresses JPEG, PNG, and WebP files without visible quality loss. Resolution stays the same; perceptual quality is preserved.

# Before          # After
banner.jpg        banner.jpg
──────────────    ──────────────
Size:  240 KB     Size:   72 KB
1920 px           1920 px
Quality: 100%     Quality: visually identical

Approximately 70% file size reduction on unoptimized source images.

Brotli Compression

Brotli is used instead of gzip for modern browsers that support it. Older clients automatically receive gzip.

# Before                      # After
Content-Encoding: gzip        Content-Encoding: br
Content size:    52.0 KB      Content size:   52.0 KB
Transferred:     12.4 KB      Transferred:     8.7 KB

For text-based responses (HTML, JSON, JS, CSS), approximately 30% less data transferred compared to gzip.
