The two things to measure on an author's site
Book covers are the heaviest thing on your page and the mailing list is the only asset you own — so those are the two things worth timing before a launch, not the theme.
The short answer
On an author's site the Largest Contentful Paint element is almost always a book cover, and that single image decides how fast the page feels. Convert it, size it for the slot it actually renders into, and a throttled Lighthouse run should put LCP at or under Google's 2.5 second threshold; past four seconds, no hosting decision will rescue it.
The second measurement is delivery, not speed: does the signup confirmation actually arrive. Mailboxes on your own domain are included, outbound mail goes through MailChannels, and SPF, DKIM and DMARC records are configured for you — so the list you spend a decade building is not quietly failing at the last step.

An author site is a small, static-shaped thing: a page per title, an about page, events, and a form. Nothing about it is computationally difficult. What makes it slow is weight — covers exported at print resolution, a hero shot at full camera size, and a slider carrying six of each.
That makes the diagnosis unusually easy. Open Chrome DevTools, Lighthouse tab, Mobile, throttling set to Slow 4G, and run it three times. The report names the LCP element. On an author site it will be an image, and the network panel sorted by transfer size will show you the same file at the top, weighing several megabytes.
The second half of the job is the part nobody times: a form submission that returns a success message but never lands in a mailbox. Test that with a real address before launch week, not during it.
Find the heaviest image, then re-measure
Run the throttled Lighthouse report and read one line: which element it flags as the Largest Contentful Paint. Then open the network panel, sort by transfer size, and look at the top row. On most author sites those two point at the same file — a cover or an author photograph uploaded at full resolution and displayed in a 400 pixel slot.
Fix it in that order: resize to the rendered dimensions, let WebP conversion handle the format, then run the same three Lighthouse passes again and compare the medians. Google calls LCP at or under 2.5 seconds good and anything past four seconds poor. Most author sites cross that line on one image, not on their host.
Where the server time goes on a page of text
Once the images are honest, a book page is close to the ideal case for a server-level cache: identical for every visitor, so LiteSpeed hands over stored HTML without waking PHP or MySQL. Time it with five `curl -s -o /dev/null -w '%{time_starttransfer}'` runs and take the median; from a UK connection to a London origin the round trip alone is 5 to 15 ms, so a cached page has little excuse.
What is not cached is the form endpoint, the search page and anything you are editing. Those run the full stack, and on Sprint at $2.42/mo they are running on 1 core and 2 GB of RAM — ample for a site of this shape, and visible in cPanel's Resource Usage graph if it ever stops being ample.
The signup form is a deliverability test, not a design decision
A mailing list is the only readership asset that survives a change of publisher, so the form is the most valuable element on the site — and the least tested. Submit it with a real address, then read the message headers of what arrives: Authentication-Results should show SPF and DKIM passing and DMARC aligned. Those records are configured for you here, and outbound mail leaves through MailChannels.
Do the same test to a Gmail address and an Outlook one, because they behave differently, and check the spam folder rather than assuming. A form that reports success while its notification silently fails is the most expensive bug an author site can carry, and it costs nothing to catch.
Launch week, sized honestly
Launch traffic is a crowd of logged-out readers asking for the same pages, which is exactly what a cache is for. The risk is not volume; it is a change made on the day. Put the redesign on a staging copy, measure it there, and push it live before the announcement goes out rather than during it.
If a title takes off and you want more headroom, upgrades apply in place: Turbo carries 25 sites on one account, and Nitro brings 200 GB of NVMe with 2 cores and 4 GB of RAM. Both are settings changes, so nothing about growth requires a migration window in the middle of a promotion.
A platform that lets you check the claim
Every figure on this page has a way to verify it. The specs come off the plan page, the thresholds are Google's published Core Web Vitals guidance, and the timing command is one line you can run before you spend anything.
That is deliberate. HostingFast sells measurement rather than adjectives. An author site is not technically demanding, so the honest pitch is not more power — it is a platform that hands you the measurements: SSH access, per-site PHP switching, real logs and a resource graph.
- WebP conversion built in, aimed at the cover that is your LCP
- SPF, DKIM and DMARC configured, with MailChannels on outbound mail
- Cached pages served before PHP starts, on every tier
- Free migration, so a before-and-after test costs nothing
Why HostingFast
Standard on every plan
The image fix costs nothing
Built-in WebP conversion targets the one element that decides LCP on an author site: an oversized cover or author photograph.
Mail that arrives, and proves it
MailChannels on outbound mail with SPF, DKIM and DMARC configured — so a signup confirmation is verifiable rather than hopeful.
A cache that needs no configuring
LiteSpeed answers a book page from stored HTML, which is why a text-and-images site should never be slow at the server.
A rehearsal before the announcement
Staging copies let you measure a redesign and push it live before launch week, not in the middle of it.
Room for a title that takes off
Turbo and Nitro apply in place, so extra CPU never means a migration during a promotion.
Restores you run yourself
Daily backups with self-service restore from the panel, files or database, without waiting in a queue at three in the morning.
Quick Start
From order to online
- 1
Run one throttled Lighthouse pass
Chrome DevTools, Lighthouse, Mobile, Slow 4G, three runs, median taken. Note the LCP figure and, more importantly, which element it names.
- 2
Resize and convert that one file
Export the cover at the dimensions it actually renders into and let WebP conversion do the format. Then repeat the same three passes and compare.
- 3
Send yourself a signup confirmation
Submit the form with a real address, open the message headers and check that SPF and DKIM pass and DMARC aligns. Repeat to a second provider.

Frequently Asked
What people ask us most often
My book covers look fine to me. Why would they be the problem?
Because you are looking at them on a fast connection on a large screen. Run Lighthouse on Mobile with Slow 4G throttling and it will name the Largest Contentful Paint element; on author sites that is nearly always a cover. A 2 MB JPEG rendered into a 400 pixel slot is pure waste, and resizing it is the single biggest win available.
How do I know my mailing list signup actually delivers?
Test it with a real address and read the headers. The Authentication-Results line should show SPF and DKIM passing and DMARC aligned. SPF, DKIM and DMARC are configured for you here and outbound mail goes through MailChannels, but the only proof is a message you received, so check Gmail and Outlook separately.
Do I need a bigger plan for launch week?
Usually not. Launch traffic is logged-out readers asking for the same cached pages, and a cache hit never reaches PHP or the database. If you want headroom anyway, Turbo or Nitro applies in place from the client area, with no migration and no downtime.
Is a page builder going to slow the site down?
It can, and the way to find out is to measure rather than argue. Build the page on a staging copy, take a throttled Lighthouse run, then compare it with the same page built plainly. Watch INP as well as LCP: builders tend to cost you interaction responsiveness rather than first paint.
