While it would be great to see an improvement in speed and
performance of MapXtreme Java over existing machine language applications,
JAVA code is interpreted (by a VM), and VM technology has to mature far
beyond where it is today before JAVA can be a competitor to C++ & Delphi
implementations. And yes, multithreaded applications do have SIGNIFICANT
advantages over applications that are not multithreaded, but depending on
what OS you run, you are limited by the number of processors that a
particular OS can support.
And as far as seeing MapInfo Professional having multiprocessor
support in the near future...Don't hold your breath. MapInfo seems to be
too wrapped up in JAVA and Internet based technology to care too much about
the tiny little desktop systems running MIPro.

Subject: MI MapInfo Professional JAVA version down the road?
Hello list,
As a MapInfo users since v 3.02 on a Mac, I now use it on Win 95 and Win
NT 4. I am faced with what most of us are the lack of processing speed
in large computational models. For example, working with large DEM / DTM
data sets within Vertical Mapper can be painfully slow. Now that I am
using a PIII 600B Mhz machine with 256 MBs of RAMBUS memory it's much
better than on the PII 350 Mhz machine with 128 MB of SDRAM. However,
using NT with two Processors and MapInfo, I can see so much more
potential.
I assume that MapXtreme Java Edition is multithreaded as JAVA C++ is a
an ideal environment for this. However, it may not be. I have talked
with the tech's at Northwood Technologies Ltd. (formerly Northwood
Geoscience Ltd.). The have said that the Java Editions they are working
on for some of their future products work slower than the non-java
versions. I am wondering if they are testing this on multi-processor
systems as well as single processor systems.
With the advent of Win 2000 helping to merge the multimedia capabilities
of Win98 and power of NT I think that down the road OS's will demand
multiple CPU's and that MapInfo should start reconfiguring it's line two
work in this environment, the sooner the better.
I have talked to a friend of mine that used to work at an ESRI partner's
software development company. He said that to his knowledge neither
ARC/INFO nor Arcview were multithreaded and that is a shortcoming.
Just imagine running MapInfo (multi-threaded) on a 32 CPU high end
workstation or MapExtreme on a server, several GBs of RAMBUS or DDR RAM
and a couple 36 GB SCSI 3 HDs...
Too only dream,
