CloudatCost Connection Slow
-
I'm having an issue with my primary web server, which runs on CloudatCost. It's a Ubuntu 14.04 server and is running Wordpress on MySQL. The issue is that the pages take FOREVER to load. I've checked the IOPS and they don't appear to be the issue. The VM is running on an SSD, so access times shouldn't be an issue. I use a caching plugin to try and help deliver the content more quickly but I'm not sure if it's helping. Pages seem to take close to 10 seconds or more to load. Is this just me or is this a common issue for everyone? The site runs on a Dev2. It's supposed to have a 100Mb connection. Not sure why it's loading so slowly...the connection is actually much faster when I run it on my home server on that FiOS connection. Any ideas?
Thanks,

I should also add that I often experience significant delay when connecting with SSH sessions to my Linux boxes. When I RDP to my DC, I don't have any of these issues.
-
Just tried and load times seem fine to me. Maybe the issue isn't with C@C but some route between you and them.
-
That it runs on SSD doesn't help much. IOPS issues are the same regardless of what you run on. If you have a Wait State or choke on IOPS it doesn't matter what is provided them.
-
100Mb (not MB) connection speed won't matter. It is unlikely that you are getting above 5Mb/s as web pages just aren't big enough to speed up much more than that.

Likely it is MySQL processing speed. What is the output of "free -m"?

Looks like MySQL can't load completely into memory. What do the last few lines of SAR look like?

I have that installed but what specific command do you want me to run? Just "sar"?
-
Yes, just sar.

Didn't have data collection enabled. I've gone ahead and enabled it. I'll let you know.

Also, I wouldn't think my MySQL databases were that big. When I do the dump of my biggest database, it's barely over 200MB...
-
That's a lot to have loaded into memory when you only have 1GB total, though.

Memory usage seems fine...
-
Memory usage IS fine, but that doesn't mean that MySQL is running totally in memory. You are mixing concepts.

Is there a way to force it?

No, it will detect if there is enough memory available and use it if possible.

Hmmm....might have to upgrade to a Dev3...
-
The coupon here (http://mangolassi.it/topic/4295/cloudatcost-50-off-upgrades-limited-qty/3) still works. Upgrading to a Dev3 for my web server from a Dev2.

My guess is that you will see a bit of an increase. You had stuff going out to swap to keep your cache fresh. It's enough but far from fully tuned.
