James,

I had our LDM developer Steve Emmerson "tune" your reg exp's.

and we cleaned up your request to ease the burden on your network.

Please let us know if you encounter any problems,

Enjoy,

Jeff

> request CONDUIT ".*" f5.aos.wisc.edu

Change this to

    request CONDUIT "/MT.ruc_CY" f5.aos.wisc.edu

...

Change the following

       CONDUIT
    ^(.*)/MT.ruc_CY.(..)/RD.(....)(..)(..)/PT.grid_DF.gr1/(.*).bgrib20
               FILE    data/nws/grids/ruc2/bgrib20/\3\4\5-\2.bgrib20.ruc2.grb
       #
       CONDUIT
    ^(.*)/MT.ruc_CY.(..)/RD.(....)(..)(..)/PT.grid_DF.gr1/(.*).sgrib20
               FILE    data/nws/grids/ruc2/sgrib20/\3\4\5-\2.sgrib20.ruc2.grb
       #
       CONDUIT
    ^(.*)/MT.ruc_CY.(..)/RD.(....)(..)(..)/PT.grid_DF.gr1/(.*).us20km
               FILE    data/nws/grids/ruc2/pgrib20/\3\4\5-\2.pgrib20.ruc2.grb

to

       CONDUIT
    /MT.ruc_CY.(..)/RD.(....)(..)(..)/PT.grid_DF.gr1/.*bgrib20
               FILE    data/nws/grids/ruc2/bgrib20/\3\4\5-\2.bgrib20.ruc2.grb
       #
       CONDUIT
    /MT.ruc_CY.(..)/RD.(....)(..)(..)/PT.grid_DF.gr1/.*sgrib20
               FILE    data/nws/grids/ruc2/sgrib20/\3\4\5-\2.sgrib20.ruc2.grb
       #
       CONDUIT
    /MT.ruc_CY.(..)/RD.(....)(..)(..)/PT.grid_DF.gr1/.*us20km
           FILE    data/nws/grids/ruc2/pgrib20/\3\4\5-\2.pgrib20.ruc2.grb

You'll get at least an order of magnitude speed-up in the
regular-expression handling (you can verify this using the regex(1)
utility that comes with the LDM distribution).

Regards,
Steve Emmerson
