problem with myisam should upgrade to vb4?

[hollyboy]

hi,

got a large board (100.000 users) and i'm having issues with myisam which is according to my hosting using a lot of server loads (im on dedicated server)

so my hosting suggested to upgrade to vb4 because the myisam there is manages better

is that true? should i do it or are other ways to manage and decrease usage of myisam?

thanks

I dont think your host has much idea what they are talking about tbh.

What issues exactly are you having ?

What issues exactly are you having ?

Issue is myisam table is overloading my server so much that it crashes.
Do you have any suggestions?

At the moment my server's machine is the following:

Dell PowerEdge 860
Intel Quad Core Intel(R) Xeon(R) CPU X3210 @ 2.13GHz
4 Gb RAM
2 x 250GB DISCO Raid1


My forum details:
- registered users: 100.000 (regular: 50.000)
- threads: 29.815
- messages: 6.601.228

You need to be more specific.

How is myisam table "Overloading" your server exactly ?

What table ? What precisely happens ?

My forum is a bout a football team.
When we are in the game day the users connected to the frum increase a lot.
So the hosting says when the users number increase the myisam of the post table get crazy and the server crashes.

Hope I was clear (not a big expert of server and tables, but I think I reported exactly what the hosting says)

You need to find out why the client(your site) couldn't query the server.

How many connections are you allowed and are you making a bunch of long queries?

[hollyboy]

dont understand "bunch of long queries?"
anyway the forum is super slow i got 800-900 users connected...i had to put forum offline :(

That message usually means the mysql timeout is too small, something your host controls.
