Re: [boost] Random Access to Files (RAF) - any interest ?

 Nice:-) I'd like to see more methods such as push_back, though resize
could make it but not so convenient. And are there any plans for supporting
insert/erase a record or a range of records?

Here are some more timings, FYI. All tests were performed on WinXP SP2
with P4 3GHz HT, 1G memory, using test.cpp compiled by VC8 (cl /O2 /EHsc).
Sequential tests read/write on a file sized 40M, while random tests were
also
limited to 1,000,000 iterations.

Test type         stub cstdio fstream randfile
----------------------------------------------
Sequential read   0.03   6.87   23.76     0.05
Sequential write  1.70  10.09   11.61     1.97
Random read       0.03   4.31    9.58     0.05
Random write      0.09   7.42   13.56     0.09
Random read/write 0.14   6.95   13.34     0.14

ps: cstdio and fstream implementations are those shipped with VC8.
