Speed of processing a bdh call using Rbloomberg

Dear list,

When I run a bdh call which requests three years of quarterly data on
two items for 48 companies (giving a 601x4 data frame), the call takes
about two minutes to complete. I would like to run bigger requests, so
speed is a bit of an issue. Is there anything I can do to improve the
speed? Code below. I have a PC running Windows 7, 4gb of RAM and a
3Ghz processor, if that matters. Java version is 1.6.0_26.

Thanks in advance
Aidan
