Not even contrib IMO. Server code wasn't even published,
there's just a Windows 32-bit server executable uploaded
to the repo with a 2 users limit.
only temporary, is not decided yet.
The rest is copy paste from letodb code, existing RDDs
and file handling routines with modifications.
is not a copy of letodb, letodb is an rdd, and File Remote server
only changes API hb_file* by hb_filenet* for existing rdds.
AFAICS low level file handling routines were replaced
with one which work through the network directly, essentially
creating a replacement for networked file system protocols,
like SMB. As such, it will have all the problems of file
server based db access. F.e. whole index handling seems to
be done through the network (not on the server side), so it
won't make indexes any more bullet proof, or substantially
reduce network traffic.
OrdCreate has been changed to decide where is the index local or
remote (obiously local for temporary indexes)
Remote file system, removes concurrence problems and in this case
works more efficient than local ones.
this are the tests:
LOCAL LOCAL LOCAL REMOTE REMOTE REMOTE
v.2 DBFCDX BMDBFCDX REDBFCDX DBFCDX BMDBFCDX REDBFCDX
single user 7.34 4.16 40.97 859.80 519.56 214.69 simulated
concurrent forced by system (W-2000)
single user 38.90 18.61 11.45 158.00 non
concurrent (W-XP)
multi user 751.00 399.50 166.30 real
concurrent
the server will be run under linux too, but not tested yet.
3 times faster than other RDDS when 2 or more client open the same remote table
at the same time.
the test is:
