[Geomoose-users] [Geomoose-developers] Speed

Wed May 28 10:52:14 EDT 2008

One trick you can use to debug your layers and actually figure out which
ones are the slowest. To use MapServer's log/debug keywords take a look
at these web pages
http://mapserver.gis.umn.edu/development/rfc/ms-rfc-28/?searchterm=debug
and http://mapserver.gis.umn.edu/docs/reference/mapfile/layer (DEBUG
parameter).

It doesn't surprise me that your tiled Mr. SID layer is slower now.  Mr.
SID already has overviews built in to it so there is no advantage to
tile a Mr. SID or ECW format.  The only formats that are worth tiling
are JPG and TIFF.

Also in regards to Web Server tuning, make sure you have HTTP
compression (aka GZIP) turned on.  In IIS this is a bit of a pain but
well worth.  What are the specs of your websever?

I built spatial indexes for most of the larger shapefiles I'm using and
I tiled my MrSID, neither really helped with speeding up my application.
The spatial indexes helped a little, but not much and the tiled MrSIDs
were actually slower than the composite image.  I don't really
understand how it could be slower, but it was about 2 to 3 seconds
slower when zoomed in and about 20 seconds slower at full extent.  Is
there anything else I can try before I explore the speed of our
webserver?  I'm guessing we just have a poor server or my symbology and
labels are too extensive.

Adam,

It essentially is ready to go, unless Dan had something he was planning
on adding yet.  Dan?

Dan are we going to call this 1.4 or 1.6?

To keep inline with how mapserver does versioning we'll keep odd
subversions as development versions and even subversions as production
versions.

I'd love to have more testing done but notwithstanding any input from
Bob and Jim, I think we can probably look at creating a 1.4 package
release towards the end of the week.

-Duck

PS: Brian, we should probably create a "migration" guide from 1.0 for
1.4.

GeoMOOSE users,

I have created a GeoMOOSE 1.4 MS4W package for beta testing.  If anyone
wants to try it, you can download it from our ftp site at:
ftp://www.houstoneng.com/Public/BrianF/  We would welcome anyone that
wants to do some beta testing on it to make sure we haven't missed any
major bugs.  The major addition is we completey re-wrote the printing
feature all in PHP mapscript.

There is no new documentation or migration guide yet, but we are working
on that.  We are also working re-organizing the files on sourceforge to
possibly automatically build the MS4W package from the sourceforge code
trunk.  More to come...

Subject: [Geomoose-developers] SHP converted into PostGIS or MySQL
To: geomoose-developers at lists.sourceforge.net,

For performance reasons, I may need to convert SHP's into a spatial
database. I loosely understand the concept of how this work but my
questions to anyone reading are:

1. Has anyone looked into specifically doing the above with their
working demo of GeoMoose using SHP files previously? I would hate to
scrap the work I've done utilizing the excellent usability of GeoMoose
in favor of utilizing a spatial database.

2. If users are typically accessing data but not writing it, will I
realize a performance upgrade *typically*.

3. Is there any functionality I can expect to break and essentially head
into an 'uncharted territory' if I did indeed attempt this. Can I
basically expect to find in my way a high level of techincal issues (I'm
very technical, but I am trying to find an efficient approach)

Also, here is a description of what I had attempted to do...

We have an OS X server which contains 2 dual core Xeons processors and
4GB of ram. We are mainly a Windows house and had aquired the hardware
in an anquisition and would like to utilize this hardware as best as
possible. This is one of our more ambitious products we one day would
like to offer our clients (we currently offer an Access product that is
quite dated.).

Originally, I had suggested perhaps getting Parellels VM software and
just bringing a copy of Windows Server 2003 to the table, but my
performance almost seems better on my test machine... I'm not sure if
that will apply to concurrent users which is certainly an aspect of the
issue at hand, but the VM software only detects 1 core... not good. We
are not looking at VMWare or anything where the license will exceed or
approach the cost of a new server otherwise we will do so.

If I host PostgreSQL or MySQL on the server and away from the server
that would host GeoMoose (a new server) I would hopefully like to
utilize the Mac in this way seeing as how I can not get the performance
I would like out of virtualized hosting.

Yes, I realize I can just set up Mapserver for OS X but, in my oppinion,
it is a very laborious task and I am foreseeing I will be the one having
to maintain this server and while I myself and relatively comfortable
maintaining OS X and its Unix skeleton, I want to minimize the work I
need to do to this server...

I will post this on GeoMoose mailing list as well as Mapserver as I
realize there is some overlap in exactly what area's this does cover.

At any rate, any input is appreciated.

Thanks,
Nelson
