A2 Hosting Performance: Benchmarks, Latency & Limits 2026
hosting.com runs LiteSpeed, AMD EPYC and NVMe across six lines from $2.99. Independent tests saw 462ms US TTFB and 99.94% annual uptime with 49 incidents.
A2 Hosting Performance verdict
hosting.com, formerly A2 Hosting, runs LiteSpeed Enterprise with HTTP/3.
AMD EPYC and NVMe on CloudLinux across a six-line catalog, from $2.99 shared up to 64-core VDS and bare-metal dedicated. Independent hostingstep Q4 2025 testing, 525,600 tests across 40 cities, measured 462ms US TTFB and a 43ms load-test response at 0% error, 5th of 34.
Use the catalog explorer to match workload to line. Lightweight WordPress or brochure sites fit shared Starter or Plus. Database-heavy or WooCommerce sites want Pro or Max, or a managed VPS for more vCPU and I/O headroom. Predictable heavy load belongs on VDS or dedicated. For sub-200ms TTFB or true auto-scaling, look to cloud-native platforms. Watch reliability even above the 99.9% SLA, since the 2025 annual figure saw 49 incidents.
- TTFB of 462ms in the US and 544ms globally is mid-tier, since premium managed or cloud-native hosts typically reach 150 to 350ms. Europe at 628ms and Asia at 744ms sit higher, so origin choice matters.
- Full-year 2025 uptime of 99.9425% with 49 incidents is labelled Below Average Reliability by the independent benchmark, though the Q4-only 99.98% is more favourable across three months. The 20x faster claim is vendor marketing combining Cloudflare CDN with SwiftServer, reproduced by no independent benchmark.
- No auto-scaling exists on any tier, so a site that hits its IOPS, 1,024 on Starter, or I/O ceiling of 50 MB/s must move up a plan or product line by hand.

A2 Hosting reliability and architecture
- All plans run LiteSpeed Enterprise Web Server with free LiteSpeed Cache and HTTP/2 and HTTP/3 (QUIC), on AMD EPYC CPUs and NVMe SSD; the rebrand made these standard on every tier, not just the old Turbo plans
- hosting.com commits to a 99.9% uptime SLA with a 5% service credit per hour of unscheduled downtime beyond the 0.1% threshold, capped at the full monthly plan fee; managed WordPress plans carry a 99.99% guarantee
- Shared accounts run on CloudLinux OS, which isolates each account's CPU, RAM and I/O into its own lightweight virtual environment so one busy neighbour cannot starve the others
- Security is layered: Monarx behavior-based AI malware detection, a Web Application Firewall, brute-force detection, DDoS mitigation and free Let's Encrypt SSL ship on every plan
- Daily automated backups are stored off-server with a 30-day restore window on shared plans (14-day retention on managed WordPress); since the rebrand restores are included rather than charged
- The live status page records cluster slugs across US servers plus Singapore (sgp1), Mexico (mex1) and Canada (can1); multiple June 2026 cluster incidents were opened and resolved within the window
A2 Hosting benchmark results, independently measured
- Independent hostingstep.com Q4 2025 testing (October to December, 525,600 tests, 40 cities, 60-second intervals on a WordPress site on the Starter plan) recorded a US average TTFB of 462ms and a 544ms global average
- In the loader.io load test (0 to 100 concurrent users over 60 seconds) hosting.com averaged 43ms with a 0% error rate, scoring 9/10 and ranking 5th of 34 tested providers
- The WPBench hardware score for the Starter plan (2 GB RAM, 2 vCPUs, NVMe, AMD EPYC) was 5.5/10, category Moderate, reflecting modest entry-level resources for a low-cost shared plan
- Q4 2025 uptime was 99.98% (score 9/10), exceeding the 99.9% SLA, but full-year 2025 monitoring recorded 99.9425% with 49 incidents and 5 hours 1 minute of downtime, which hostingstep categorizes as Below Average Reliability
- The vendor 20x faster claim pairs the SwiftServer platform with Cloudflare CDN and is marketing language, not an independently reproduced benchmark; independent TTFB of 462ms places hosting.com in the mid tier
A2 Hosting Performance FAQ
How fast is hosting.com (A2 Hosting) in independent tests?
Independent hostingstep Q4 2025 testing, 525,600 tests across 40 cities, recorded a US average TTFB of 462ms and a 544ms global average. Europe ran 628ms, Asia Pacific 744ms and London 1.1s, placing hosting.com in the mid tier. Its load-test response was strong at 43ms with a 0% error rate under 100 concurrent users, ranked 5th of 34 providers. LiteSpeed caching lowers page-load time but not origin TTFB materially.
What product lines and plans does hosting.com offer?
Six lines spanning 25 tiers. Web shared runs Starter to Max, $2.99 to $8.99 intro. Managed WordPress runs Small to Turbo, 30k to 500k visitors. VPS covers managed 4 to 32 GB and unmanaged XS to L. VDS runs 24 to 64 cores and 64 to 256 GB. Bare-metal Dedicated is US-only and sales-quoted, and white-label Reseller runs 30 to 150 cPanel accounts. The catalog explorer on this page lets you browse each line's specs and flip between intro and renewal pricing.
Does hosting.com support auto-scaling?
No. There is no horizontal auto-scaling on any tier. Within shared hosting, IOPS run 1,024 on Starter to 8,192 on Max, and I/O bandwidth 50 to 250 MB/s. These are hard per-account ceilings, so a site that exceeds them throttles until you manually upgrade. Scaling means moving up a plan or to a higher product line, VPS, VDS or dedicated.
What is hosting.com's uptime SLA and actual reliability?
The SLA is 99.9%, or 99.99% on managed WordPress, with a 5% monthly-fee service credit per hour of unscheduled downtime beyond 0.1%, capped at the full monthly fee. Independent Q4 2025 monitoring showed 99.98% actual uptime, but full-year 2025 monitoring recorded 99.9425% with 49 incidents and 5 hours 1 minute of downtime, categorized Below Average Reliability.
What web stack does hosting.com run?
LiteSpeed Enterprise Web Server with free LiteSpeed Cache and HTTP/2 and HTTP/3 over QUIC, AMD EPYC CPUs and NVMe SSD, on CloudLinux OS for per-account isolation. A Cloudflare CDN with 100+ edge locations is available on all accounts. Since the 2025 rebrand from A2 Hosting, LiteSpeed and NVMe are standard on every tier rather than Turbo-only.
Is the 20x faster claim independently verified?
No. The 20x faster claim on the Cloudflare integration page pairs the SwiftServer platform with Cloudflare CDN and is vendor marketing, not an independent benchmark. Independent hostingstep testing recorded a 462ms US TTFB, mid-tier and well above the sub-200ms achievable on premium managed or cloud-native platforms.
