[PATCH 055/143] USB: serial: sierra driver performance improvements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Elina Pasheva <epasheva@xxxxxxxxxxxxxxxxxx>

- Version number set to 1.3.4
 - Increased the number of input/output URBs for improved performance
   (numbers based on an measurement study triggered by a user request).
   We performed the testing using a network simulator that provided full
   speeds in the uplink and downlink directions and this combination of
   URBs provided the best throughput.
