WordPress Subdomain Multisite Working Slow

@ Andrea_r
Did you set up the wildcard subdomains correctly? yes
How much memory is allocated to mysql? 64M
Have you looked at any error logs? Yes
apache2 errro: nothing of interest
mysql error: nothing of interest
?

Have you sat in a terminal and did a top to watch what the server does when someone logs in?
not sure what I’m looking for, but here is the output:

Any of this help identify the problem? Thanks.

Bump deleted (really, don’t).

If you’re seeing that small loads but high memory, I’d be inclined to think your PHP setup was done poorly. Are you using eAccellerator or APC or any other SERVER side PHP caching?

@ Ipstenu

Are you using eAccellerator or APC or any other SERVER side PHP caching?

No.

I’d be inclined to think your PHP setup was done poorly.

That is very possible.
Any suggestions?

Yeah, turn on some server side caching for PHP ?? Seriously.

As for the rest … I’m NOT a PHP/server install expert, but it really depends on how you’ve set it up. This means it’s time for you to look up how best to optimize your php install for your server. Every server is a snowflake (special unto itself) so there ARE some generic tutorials, but they’re OS specific a lot of the time.

Thanks. I’m not the IT person on this project and they’ve not been overly supportive of the project or wordpress in general. That’s why I’m trying to find a solution for them. Appreciate all the help.

So we installed eAccellerator and unfortunately it doesn’t seem to be helping. https://fayettevilleforward.org/info.php
If anyone has any other ideas, they would be appreciated.

nevermind. we finally got it straightened out.

Is it helping? ??

posting what you found may help others in the future. ??

Same thing. Main domain works ok, multisite subdomains correctly mapped to top-level tlds and listed as vhosts are da-a-a-amn slow.

Would love to find an answer to this, I have the same problem on a Heart Internet reseller hosting package with any MU installation I create. The slowness varies in length, but it’s always excruciatingly slow.

@jewlzmcq I’m having you exact same issue… how did you get it straightened out? What was the problem? Pleez help ??
