Roundcube performance again

Felipe Neuwald
Hi Folks,

I disabled persistent db-connections and IMAP cache, as you can see:

db.inc.php:
// use persistent db-connections
$rcmail_config['db_persistent'] = FALSE;

main.inc.php:
// enable caching of messages and mailbox data in the local database.
// this is recommended if the IMAP server does not run on the same machine
$rcmail_config['enable_caching'] = FALSE;

Again, my server performance hangs with a lot of httpd process, but now
after something about 15 hours of working. Any idea of how can I solve this?

PS: I'll install apache-top to understand better what's happening.

Thanks,

Felipe Neuwald.
