Thanks for the tip - that certainly did the trick.  I ran a couple requests 
through and got sub-10 seconds on each request.

That's a tip that should be documented on the wiki.  :)

Thanks again,

Jeremy

  I run the frdrmd/hades box-- mat runs the load balancer along with his two 
romas.  I ran into similar issues such as yours with speeds-- you need to 
create two more indexes on nodes_ways;


  create index idx_ways_big on way_nodes using btree (way_id);

  create index idx_nodes_big on way_nodes using btree (node_id);



  (those usually take anywhere from 10-120 minutes to process)


  As far as specs go, my roma is a really hacked together system; Core 2 Duo 
E6400, 4GB ram, SW Raid0 across 7 random hard drives I had in the basement.  
  Phpsysinfo;
  http://frdrmd.roma.osm.phyrefile.com/phpsysinfo/
  And pretty munin graphs;

  Let me know if the problem persists after adding the indexes.

    Hi all,

    First I wanted to say thanks to Mathieu providing these two servers for
    client use.  I'm sure they'll be a big help once they're in general use in
    the stable client.

    I have been attempting to bring my own ROMA server online as yet another
    ROMA option (YAROMAO??), but I'm not seeing anything close to the same
    performance as either of these two servers.  I was wondering if you'd be
    willing to share the specs of these servers and/or tweaks and tuning you
    used to speed up postgresql so that I could compare with my server.

    For the record, my server is a 2x 3.0 Ghz Xeon with 8GB RAM and 4x 150GB
    Velociraptor drives in RAID0 on an LSI MegaRAID 8344ELP controller.
    Bonnie++ shows block reads at 426MB/s and over 700 seeks/s.

    While fetching bbox 37.221680,11.594560,37.397461,11.709906 I get data in
    sub-30 seconds from your two servers while mine takes over 130 seconds.

    I'll be the first to admit I'm not a pgsql admin, so there hasn't been much
    tweaking done to the config on my server.

    Any help would be greatly appreciated.

    -Jeremy

    Subject: [Tilesathome] Two new ROMA...

    Hi,

    I'm pleased to announce that there are now three ROMA servers, the new two
    are located at frdrmd.roma.osm.phyrefile.com, api1.osm.absolight.net.

    There may be some rough edges, but both have been serving a few clients for
    some time now.

    There also is a haproxy (which may still need tuning, but, hey, can't know
    that untill more people use it.) located on the last server, the simplest
    way
    to use it would be to put :

    API_ROMA = http://api1.osm.absolight.net:8080/api/%v/map?bbox=%b

    in your tilesAtHome.conf.

    If you don't want to change that old ROMA url, you could do :

    APIServers = ROMA2,API,ROMA,XAPI
    API_ROMA2 = http://api1.osm.absolight.net:8080/api/%v/map?bbox=%b

    which would let you keep a backup in case the haproxy goes down and the main
    API and the XAPI goes down too :-)
