Now we have discussed about the tools we used to manage our server performance let us talk about some specifics in each of the most important resources of our servers. So again we are going to focus on the memory, processor, disk sub system, and network sub system. These are the 4 life bloods of any computer system. And these are the 4 aspects of the server that we need to make sure that we optimize in order to have the best network that we can have so lets talk about memory first. There is 2 types of memory RAM which is the physical memory which is very fast and then there is virtual memory. Virtual memory is memory that is actually held on a disk on the hard disk and then it is transferred to RAM to physical memory right before it is used. This is process is called paging because it held in special place on the disk called page file. We want to keep paging to a minimum because paging is much much slower than just using RAM. Therefore the more RAM we have the better and on Microsoft test question chances are if one of the option is to add more RAM then you consider that option very strongly. I am not going to say that always the right answer because might not be but I would consider that very strongly RAM affects everything. if we this that we are having poor disk performance it might just be the that, that disk that it is having poor performance where it is busy with its page file and the real problem then is that we do not have enough RAM. So how do we know ? How are we suppose to look for ? We talked about how to set up the counter. We did that in the last chapter so in this chapter we are going to talk about what we want out of this counters. The pages per second counter should be between 0 and 20. It should not be higher than 20 pages per second. If it is we need more RAM. The available bytes should be at a minimum at a 5 percent of the total memory. In other words we shouldn't be using all of our memory. We should have at least 5 percent left if it is higher than that we need more RAM. If our ****on Ram we need a bigger server. We need something that we can handle or that can handle the load that they were putting on that. Committed bytes: committed bytes are the bytes that are currently being used by the applications and the service on the server that should be less than RAM. So the average committed bytes should be less than the RAM which would mean server was running on RAM except for an extreme circumstances when, it would use the paging file and by the same token then page fault should be below 5. So page faults are the processes of the this page files being used. In other words the process of the information having to be moved from the hard disk back over to RAM so it can be used. So these are the counters that we need to look for memory. But we have certain counters that we want to look for certain things that we want to look for each of these resources that our server uses. So in our next section we will take look at the next resource which is processor.
