Optimal PHP Memory Limit and MySQL Packet Size?
 

A friend of mines vb4 install is way faster than mine, even though we have similar traffic and hosts.

I did noticed that on his admin page he had different settings for his PHP memory limit and so on. The below are mine, do any seem like they may be hindering performance?

Web Server Apache v2.2.14
PHP 5.3.1
PHP Max Post Size 64.00 MB
PHP Maximum Upload Size 64.00 MB
PHP Memory Limit 64.00 MB
MySQL Version 5.0.90-community-log
MySQL Packet Size 16.00 MB

Thanks!

These values are a bit high - aren't they ?

PHP Max Post Size 64.00 MB
PHP Maximum Upload Size 64.00 MB

64 MB uploads ? :confused:

But except these values, do you use the same OS with the same MySQL & Apache configuration on the same hardware with the same Addons to really have data to compare ?

May be the other MySQL DB is configured different or Apache :)

That I'm not sure about. It was another colleague who had setup these values I believe.

Is having those values too high going to harm performance?

Well, you may waste resources you might need somewhere else.

I've a max_post_size of 5 MB, max_file_upload of 4 MB since the largest possible attachement I allow is 3.5 MB.

Still, except these values, don't forget your Webserver and Database - also Firewalls might give some performance impact while being useless in the most cases

Thanks! I'll see about toning down those numbers.

Swiftor,

Are you a shared, vps, or dedicated server?

Thanks,

I recently transitioned to a dedicated server, but did not adjust my settings

Thanks!

Where do you set the "largest possible attachement" size at?
