Having issues with hosting - too much "swapping"

Permalink
I've got 512 RAM with 200 GB of bandwidth and don't seem to be using anywhere near the limit, yet my host keeps freezing up because of too much "swapping".

What kind of hosting and how much RAM & bandwidth do you use for your C5 sites?

I have a feeling the WPMU site that is on this host might be the culprit, but even that only gets 100-1000 visits a day max.

My site 4GB RAM

point of setting.

my.cnf for MySQL 
key_buffer      = 64M
max_allowed_packet   = 16M
thread_stack      = 128K
thread_cache_size   = 16
sort_buffer_size    = 4M
read_buffer_size   = 2M
read_rnd_buffer_size   = 2M
tmp_table_size    = 192M
max_heap_table_size   = 192M
join_buffer_size   = 6M
# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched
myisam-recover      = BACKUP
max_connections        = 100
table_cache            = 3200

Does your site get a lot of traffic? A 4GB plan for our host would be $250 a month which is just insane considering I used to host 100x bigger sites with other hosts for $500/YEAR.

Funny I was looking at that earlier. Can't get there now though to compare prices. The host I'm using now is Slicehost, which is fine if you're a developer or server pro, but I am neither.

How much RAM would we have with your hosting? I just can't figure out why we're having these problems? It doesn't seem like either of the sites hosted should be causing this, but I'm definitely no hosting pro.

unless your buying a dedicated server, or virtual private server, you're not going to really be "buying ram" that way..

i can tell you however, we don't have the types of problems mentioned in this thread on our hosting.

Yeah, that seems like a lot. Here's what our server has said since I had to reboot it the last time:
