For question #8 use the other method of obtaining the mysql stats in 2nd post at http://www.vbulletin.com/forum/showthread.php?t=70117

Try the following in this exact order. You can ignore any of the suggestions that you have already done.

1. Upgrade PHP to 5.2.3 or if you have problems install PHP 4.4.7 (in either case install as ISAPI module and NO CGI)
2. Edit /etc/my.cnf and place the following mysql server settings in /etc/my.cnf and restart mysql server afterwards


[mysqld]
#old_passwords
back_log = 50
skip-innodb
max_connections = 500
key_buffer = 128M
myisam_sort_buffer_size = 64M
join_buffer_size = 1M
read_buffer_size = 1M
sort_buffer_size = 2M
table_cache = 2000
thread_cache_size = 384
wait_timeout = 35
connect_timeout = 10
tmp_table_size = 64M
max_heap_table_size = 64M
max_allowed_packet = 64M
max_connect_errors = 10
thread_concurrency = 4
concurrent_insert = 2
table_lock_wait_timeout = 35
read_rnd_buffer_size = 524288
bulk_insert_buffer_size = 8M
query_cache_limit = 4M
query_cache_size = 64M
query_cache_type = 1
query_prealloc_size = 131072
query_alloc_block_size = 65536
default-storage-engine = MyISAM
ft_min_word_len=3

[mysqld_safe]
nice = -5
open_files_limit = 8192

[mysqldump]
quick
max_allowed_packet = 16M

[myisamchk]
ft_min_word_len=3
key_buffer = 64M
sort_buffer = 64M
read_buffer = 16M
write_buffer = 16M


3. Install lastest version of Xcache 1.2.1 final which has support for Zend Optimizer as well.

4. If you just upgraded to vB 3.5.x/3.6.x try to disable these 4 options:

Admin CP -> vBulletin Options -> Forums Home Page Options -> Display Logged in Users?

Admin CP -> vBulletin Options -> Forum Display Options (forumdisplay) -> Show Users Browsing Forums

Admin CP -> vBulletin Options -> Thread Display Options -> Show Users Browsing Thread

Admin CP -> vBulletin Options -> Message Searching Options -> Automatic Similar Thread search

5. Edit httpd.conf values to following and restart apache

KeepAlive: On
MaxKeepAliveRequests: 100
KeepAliveTimeout: 1

<IfModule prefork.c>
StartServers 15
MinSpareServers 15
MaxSpareServers 20
MaxClients 180
MaxRequestsPerChild 1000
</IfModule>
