[Koha-devel] System use and best way to beef up a machine

[Erik Lewis]

Hi David,

Personal opinion but I'd look at the actual traffic.  Right now you  
don't know if it is user or application.  The most efficient way to  
answer that question is to determine if the barcode is being  
transmitted.

Maybe mirror a port on a switch and attach a desktop to that port and  
then use ngrep to capture the relevant traffic of a checkin.  You  
should be able to generate a list of barcodes and then run them  
against your koha system to determine if the barcode was sent.  If it  
was sent and not applied then you can investigate the host.  If the  
barcode wasn't sent you can investigate the client.
