I’ve been running both HestiaCP and cPanel in production, so I compared them using real server workloads rather than spinning up identical empty VPSs and running synthetic benchmarks.
This was not a controlled benchmark. The hardware, websites, and workloads are different, so I wouldn't use the results to claim that HestiaCP is inherently faster than cPanel. I was more interested in seeing how the two architectures behaved under normal production conditions.
I measured approximately 24 hours of web traffic across three servers:
- Hestia server 1: ~73,700 requests, 29 configured domains
- Hestia server 2: ~182,500 requests, 9 configured domains
- cPanel server: ~47,500 requests, 4 hosting accounts
All three were running real production workloads. The logs also contained plenty of the usual Internet background noise: XML-RPC attacks, wp-login attempts, PHP probes, crawlers, etc. The firewalls had already been tuned to block much of the abusive traffic before it reached the application layer.
One of the more interesting results was process behavior.
During one WordPress burst, the cPanel server expanded to 87 Apache processes (~1.29 GB aggregate RSS) and about 1.5 GB of PHP-FPM RSS. A few minutes later, Apache was back to 11 processes (~176 MB), and PHP-FPM had dropped to about 50 MB.
The Hestia servers generally maintained a much smaller active nginx/Apache footprint during the snapshots, even while processing substantial traffic.
But request count turned out to be misleading. The Hestia server processing ~182,500 requests wasn't necessarily doing four times the work of the cPanel server. A lot of its traffic came from a relatively lightweight non-WordPress application, while the cPanel workload was more WordPress-heavy.
I also ran 30-request response-time tests against a representative WordPress site on each server.
With caching working, there wasn't much of a contest: all three generally returned pages in roughly 0.12–0.19 seconds.
When I used cache-busting requests to force substantially more application/origin processing, the difference became much larger. Approximate median TTFB was:
Hestia server 2: ~1.31 sec
Hestia server 1: ~1.70 sec
cPanel server: ~1.83 sec
Again, those aren't identical WordPress installations, so I don't think it's valid to attribute that difference solely to the control panel.
The more interesting conclusion for me was this:
The biggest performance difference I measured wasn't Hestia vs. cPanel. It was cached vs. dynamically generated WordPress requests.
The control-panel architecture definitely affected process behavior, and Hestia looked impressively lean in these deployments. But caching, PHP workload, WordPress configuration, firewall/bot mitigation, and the actual type of requests being processed appear to matter enormously.
One other disclosure: both Hestia servers are completely behind Cloudflare. The cPanel server has a mixture of Cloudflare-proxied and direct-origin sites. For the response-time comparison, I specifically chose Cloudflare-proxied sites on all three servers to reduce that variable.
I wrote up the full experiment with the methodology, workload tables, memory/process measurements, and limitations here:

I'd be interested to hear from anyone running both HestiaCP and cPanel—particularly whether you've seen the same difference in Apache/PHP-FPM process behavior during WordPress traffic bursts.
