Slowing of the crash site and phpMyadmin

Hello

I am currently doing a site for an association.

I have a dedicated server:

When there are around 20 people on this site, slowing down and crashing phpMy Admin.

I feel that the treatment of the database is delayed and at the end she can not keep up. I have a minimum module.

Anyone have a solution?

Thank you in advance.

something surely seems odd on this. we can take a look at what is going on, and try to do some optimizing on the database and caching system.

This helps a lot. Especially that frankly I am in complete darkness. even the logs do not give me the error.

How I proccèder?

I am sending you data access to the site and serverby private message?

Anyway thank you for your speed

 i have sent you a PM

Research on the forum  OVH - a lot of negative comments on the 64-bit
- With 32-bit - D7 works well

 Merci pour  l'achat du template

thank you Daniel

I just reinstall a 32-bit, but I do not understand is thatthe other server sites in dolphin turned smoothly. Onlythe one who makes me whole plant.

So I redo the transfer of a 32-bit and I'll see the resultlater in the day.

For your template, it is lovely.
