    How to decrease/check I/O time call



      How to decrease/check I/O time call

      Your post


           I have a problem with FileMaker Server 11 Admin Console version

           To set the scene first inform the server hardware:

           Model Name: Mac mini
           Model Identifier: Macmini3, one
           Processor Name: Intel Core 2 Duo
           Processor Speed: 2.26 GHz
           Number of Processors: 1
           Total number of cores: 2
           L2 Cache: 3 MB
           Memory: 4 GB
           Bus Speed: 1.07 GHz

           As for the hard drive:
           Capacity: 500.11 GB (500,107,862,016 bytes)
           Model ST9500325AS
           Native Command Queuing: Yes
           Queue Depth: 32
           Removable media: No
           Removable Drive: No
           BSD Name: disk0
           Speed: 5400
           Media Type: Rotary
           Name compartment: Lower
           Partition Map Type: GPT (GUID Partition Table)
           S.M.A.R.T. Status: Verified

           The server brings service to 13 clients. Sometimes these terminals must wait a considerable time since the accesses to a layout until the information is showed.

           If through Admin Console I look at the statistics, I realize that the parameter “I/O Time Call” has a value of 6619 (average) and 13360763 (peak), which, from what I can make out are very high numbers. This parameter indicates the time a remote call waits for the disk read or write, therefore a first solution that comes to my mind is to change the disc. But not only could be a disk problem, but also could be a matter of general hardware obsolescence. It could also be an issue concerning  software, or network, thereby changing the server with a new one would not solve the problem.

           For all these reasons, I wander how I can verify that the problem that I have is related with hardware before changing it. What tests could I do to make sure the 6619 and 13,360,763 “I/O Time Call” are due to the server is not powerful enough?

           Thanks in advance.
