[Forum] What is the highest PHP Post Size, PHP Upload Size, and PHP Memory Size suggested?

[David Copeland]

I had posted something similar to this question in another thread, but some of the responder posts have disappeared.

I have contacted my web host provider, and they have increased my of:

PHP Post Size to 20.00 MB
PHP Upload Size to 4.00 MB
PHP Memory Limit to 128.00 MB

What does VBulletin recommend for Ver 4.2? I ask this because my host indicated there might be some vulnerability to going over the preferred limits.

(And to other members, what do you have your settings at?)

Thanks,

David

I would still like to get feedback on this.

In the meantime, our host has increased the resources to the following:

PHP Post Size to 200.00 MB
PHP Upload Size to 100.00 MB
PHP Memory Limit to 512.00 MB
MySQL Packet Size to 32.00 MB

What are you trying to do that you think you need these higher limits?

Why on earth would you want to increase your post_max_size to 200MB and upload_max_filesize to 100mb? I would keep those low if you can. If you allow users to post or upload massive sizes then its easier to take your site down.
Memory limit of 128 can be low. I needed more for my big board. It depends on your site. 512 is steep for most sites.

For maximums...
PHP Post size should be 16 MB + Largest attachment Allowed in vBulletin. Attachments shouldn't really be larger than 4-8 Megabytes for performance reasons. Use FTP for larger files.
PHP Upload should be just over largest attachment allowed.
If a dedicated server without resource problems, you can probably get away with setting memory to -1. However 512 MB should be sufficient.

MySQL Packet size should be no larger than 17MB. You should store attachments in the file system.

If you're trying to share 100 MB files, then you should upload them via FTP and link to them in posts. You shouldn't attach them.

What do you mean by memory at: -1 ?
Is -1 the same as 1GB? If not, is -1 larger than 520MB ?


We don't seem to resource limitations anymore since we moved to a new dedicated VPS, which costs us $120/mo.

We also do not permit our members to upload, which should not be an issue with bringing the site down.

We do not have that many Attachments to speak of.

Since we have increased all of the resource items as I posted in this thread above, our page loads are quite a bit faster, and our mass emails are not much of a load on our server.

Our forum stats are:

Members 45,783

We keep asking you what you want to do with these increased limits, otherwise there isn't a good reason to increase them.

Zack,

-1 is no limit. as such it is very different than any limit.

Wayne, perhaps you can help answer a question here:
