WordPress 3.6 and 3.6.1 so so slow on Dreamhost, anyone else?

  • Hi
    I use 1click install of WordPress on Dreamhost shared hosting. My site https://www.robotguide.com/ has been running increasingly slowly for a few months, both the site and the admin backend, it was taking about 5 seconds to load either. I contacted their support twice and was told everything was normal. It’s only a small site and I don’t get too many visitors so far. Less now!

    I upgraded to WordPress 3.6 and 3.6.1 the other day and both the site and admin take a minimum of 15-20 seconds to load any page! I have wasted nearly 3 days trying to find out why and as you can imagine having to wait 15 or 20 seconds everytime I change something to test is really frustrating, never mind lost work and site users!

    Verification of results:
    – connected through a UK VPN to check from a different location, still slow.
    – used a variety of browsers, slow.
    – other people also reporting site as slow.
    – https://bytecheck.com/ reports 15-20s for first byte
    – https://tools.pingdom.com/ typically 17s to laod site
    – website inspector reports 20s for the network request and then a few seconds to render the page
    – connecting to https://www.robotguide.com/readme.html is near instant, so it’s something to do with WordPress and the Dreamhost servers I thing!

    What I have tried:
    – disabled all plugins, still 15-20s
    – deleted all plugins, no effect
    – followed all the dreamhost faqs on their site inc database optimisation, checking memory and checking database load times, no effect
    – optimised the database. no effect
    – deleted the whole site and did a clean install of wordpress, even with a clean install and an ’empty’ database the site and admin were still about 10seconds
    – using a cache plugin like W3 total cache speeds up site loading, but working in the admin is still awful.
    – created a site on another host and imported my site, and it loaded in a few seconds!
    – hours of googling and trying stuff.

    In essence the site seems to render quickly once it starts, but takes 15-20seconds to get to that point. As the site loads quickly on another host it seems to be something Dreamhost are doing.

    I don’t really want to move to another host, but this is intolerable. I’ve posted on their support but thought I would ask here too given the last two times I have asked for help with this issue on Dreamhost support have not been useful!

    Any ideas or similar experience?

    Thanks in advance, Mike

  • mike, your posts contain a lot of images, videos etc. Consider showing only post excerpts on your home page. I don’t remember how it was handled by your old theme. Or you can use read more.

    I’ve got the WooThemes Canvas theme running again and it only shows excerpts.

    I got all the plugins re-enabled, including Jetpack although I turned deactivated all the features I don’t use. Back to about 15s load for site and admin, but with W3TotalCache running the site loads quick once it is cached :-/

    Will see what happens when Dreamhost move my server location.

    Final update:
    – I deleted another wordpress blog (my wife’s so will need to find another place for this!), so on my shared host I now have one Expression Engine site, and one WordPress site. Was a bit faster.
    – Dreamhost moved me to another server with less load and that made a huge difference, the site is now very fast again, both in loading the site and the admin pages.

    If I get time I will put the other wordpress blog back on to see what happens, but it looks like running multiple wordpress sites on a shared host will give problems with memory and procwatch.

    Thanks to everyone on this forum and at Dreamhost for their help:-)

    mike, i’m really glad to hear that your problem is solved ??

    I have had this problem myself and been moved but like any hosting company their goal is to get as many users as possible crammed onto a server.

    Dreamhost uses clusters for web servers but I gather not for SQL servers, the SQL servers are paired with clusters so you can’t improve the SQL performance without changing web server which has issues.

    The same applies to their VPS, you have to pay for a separate SQL Server.

    The clue to it not being the plugins etc is that the wordpress admin page is slow, although sometimes the admin-ajax.php script (implemented in 3.6) can cause speed issues.

    I believe the issue here is the networking infrastructure, they need to install multiple network cards and use dedicated multigigabit switches for the database traffic. I have done this with 3 NIC’s per server, 3 switches and dedicated cabling and it makes servers fly.

    I love Dreamhost but this is becoming a serious problem, even their panel is affected by this, when you have a more than a few sites and objects the panel runs like dog (20 seconds+ to populate the screen).

    What it means for me is that while I will tolerate it I can’t recommend Dreamhost to clients because it is my rep on the line.

    I have to concur with the above. I’ve used dreamhost almost since the beginning and typically the uptime, support, and page load times have been fine… until about half a year ago. The server response times are the main problem. I’m getting timeouts on traceroutes and google page speed info that the server is taking 2-5 seconds to respond to the initial request. Makes developing a real slow process. I’ve done support requests. They reboot apache and the mysql server but it is less than helpful. I’m starting to think their infrustructure isn’t keeping up with all the WP sites installed on their shared servers.

    Anyone recommend a comparable host? No to godaddy.

    Although we do not personally endorse them, there are some hosts listed here. Also searching the forums using the keywords “host” or “hosting” may provide you with some suggestions. However, due to the amount of spam that these topics attract, I’m afraid I will have to close this one.
