When a performance issue is reported it can be very difficult to find
the true cause. Often because a Synergy product or program is being
used a customer will contact Synergex Support to debug the issue.
However, the true cause is often not due to an issue with a Synergex
product.
These performance problems often fall into two categories; either an
issue with local resources or network based issue. There are two tools
available for free download from Microsoft that helps reveal the true
clause of these issues. They are Process Explorer and Microsoft Network
Monitor respectively.
Debugging issues on which local resources are consumed (CPU, Memory or
Disk I/O)
Firstly, use the multi-functional Process Explorer
(http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) and
monitor the processes for which is consuming a large amount of resources
as compared to the other running processes.
Open the Process Explorer and set the view to be as such:
View -> Select Columns
On the below tabs confirm that only the below columns are selected:
Process Image tab select Process Name and PID (Process Identifier)
Process Performance tab select CPU Usage, I/O Reads, I/O Writes
Process Memory tab select Page Faults, Private Bytes, Peak Working Set
Size
Depending on the issue monitor the columns (I/O Read/Write for disk
activity and CPU or memory based columns for CPU bound issues) for large
values or values that are being consumed in an increasingly greater
amount and observe which process(es) are responsible.
Debugging Network related issues:
Download and install the Microsoft Network Monitor (information page:
http://blogs.technet.com/netmon/). The program itself can be downloaded
from
http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b941d-06cb-4658-b7f6-3088333d062f
Once installed set the filters as such:
File -> New -> Capture
Filter -> Display Filter - > Load Filter -> Standard Filters ->Addresses
-> IPv4 Addresses
In the Display filter window edit the filter by commenting the below
line (add // as the first characters on the line)
IPv4.Address == 192.168.0.100
And un-comment the below line by removing the //
// IPv4.Address == 192.168.0.100 AND IPv4.Address == 192.168.0.200
Then edit the IP address in the line to be that of the client and
server.
Start the capture, reproduce the issue and stop the capture. Save the
capture file and send it to Synergex Support
