emulex.com website review

About 445 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

Your mobile performance score is 62. Pages that score under 90 lose visitors before the first paint.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

About 149 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

6 third-party services load with your homepage (Google Tag Manager, Optanon and Amplitude Mobile Analytics and others), adding 861 KiB and 570 ms of main-thread time.

10 files are served with short cache lifetimes, so returning visitors download them again (95 KiB).

Google Tag Manager costs a phone 351 ms of main-thread work and 360 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

Polyfills for old browsers add 32 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

A phone's processor spends 2.2 s on main-thread work while loading, 1.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 long tasks block the main thread while loading, the longest for 181 ms. During a long task the page ignores taps.

4 KiB could be saved by minifying JavaScript.

1 image could be 151 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 8.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Broadcom and our partners use technology, including cookies…”.

The page becomes fully interactive after 10.0 s. Good is under 3.8 s.

Real visitors wait 3.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.6 s (75th percentile). Good is under 1.8 s.

Real visitors wait 996 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 448 ms in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 146 ms to 153 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 4.7 s to 4.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.2 MB in 90 requests on a phone: scripts 995 KiB (22), images 468 KiB (21) and fonts 424 KiB (9). Under 2 MB keeps phones on slow connections fast.

1 image (56 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.61 g of CO₂e: 73.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 5 elements on the page fail this check, rated critical by axe-core.

Heading levels should only increase by one: 3 elements on the page fail this check, rated moderate by axe-core.

Banner landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

Elements with visible text labels do not have matching accessible names. (1 element).

There is no <h1>, so neither visitors nor Google get a clear main headline.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

A phone browser shows 465 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

4 of 20 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Chrome logged issues while loading the page (“Content security policy”).

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

broadcom.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 465 words of visible text.

emulex.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

emulex.com has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Amplitude, Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 8 cookies (measured from a US location before any click).

Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
