I’ve been with my current webhost 123reg for more than 5 years (I was with supanames) and it hasn’t been to bad. I recently re did my site with WordPress and a few plugins and noticed that the performance was awful. Searching the web i found i wasnt the only one, i suspect they squeeze as many accounts on to one server. I decided to move to another UK webhost (vidahost). Really good reviews and more of less the same price, so far it’s been really fast and responsive.
Comparison of the same wordpress install and mysql db loaded on the two webhost.
OLD Webhost 123reg – 8.22 sec
New Webhost Vidahost – 2.49 sec
Now you may think it’s only a few seconds but sometimes the site wouldn’t respond at all.
UPDATE:
I have had to use support a few times and they have responded within 30 min. Well impressed.
