Can you help me decipher this?

Still having on and off troubles with my hosts server speed. Their default answer is to blame slow sql queries then when you prove to them that there were only 3 slow queries in the last hour, then they go "wait a minute" and put me on hold for 10 - 20 minutes.

Then they tell me that I have too many processes running. So I ssh into the system and run top and get the following.

[email protected] [~]# top -u user
top - 12:11:26 up 92 days, 19:33,  4 users,  load average: 28.51, 46.37, 74.41

My questions are the following:
Obviously the tasks showing are me logged into the server but the task line shows 1554 tasks running. Are those MY tasks or the whole server?
The memory line: Is that MY memory usage or the whole server?

Looks to me like there are too many sleeping and zombie processes using up all the servers memory. Again are these processes MINE or the whole server?

If a 'bare metal' server, then it'll be for the whole server. If a virtualised server it'll be for your VM.
Although it is impossible for me to say for sure if this is indicative of a problem (without more information), this is about 10 times more than I would normally expect (in either case)

The memory line: Is that MY memory usage or the whole server?

Probably the whole server/VM, but these figures are subject to manipulation in a VM environment.

Looks to me like there are too many sleeping and zombie processes using up all the servers memory.

Zombie processes don't use any memory, The are 'dead' pointers.
Sleeping processes are (in simple terms) processes that are not being accessed by the CPU at the instant the data is being read. Typically this will be the the total number of processes, minus the running, stopped and zombie processes

Again are these processes MINE or the whole server?

Based on the output data that you have provided, these figures would be for the whole server. If it were for the user named 'user' the total tasks would be '3' (the same number of processes listed in the second section of the TOP output).

Your load average is way off the scale for acceptable performance. The abnormally high number of zombies is probably a fallout of the system not being able to handle all of the running processes, and to solve the issue you need to somehow find out what all these processes are.

As stated, the number of processes is about 10 times greater than I would expect, BUT, if the server is under some kind of attack (ddos, spam), or, even if the server processing a maillist then these kinds of peaks are not unusual. Occasionally these peaks are the result of software that fails to close network or SQL sockets. Again, you will need to determine which program/app is causing this.

Try using the 'ps' command to see if that provides further clues.

The above 3 lines tell the story. This Server is overloaded.
