i asked something about java optimization before, but i gave a very poor
example... leading to not much help... so here is a better situation.
i have a Map, and i'm constantly picking entries from random from this
map.
in one method, i only use the map.
in another method, i use an array of keys from the map, stored seperately.
method a (only the map):

Does Studio Dot Net include any optimizations that make it the appropriate
tool for Pentium 4 processors?
I'm writing a paper on compiler optimizations for modern hardware. Since I
chose .Net as my main tool, I was looking for some sites that explain some
of the optimizations .Net may have that will make it more compatible with
modern hardware.
I'm also looking for info on the differences between traditional compilers
and the Dot Net...

I've added an extra thread to my application read from an alsa midi device,
and when I compile with any optimizations (gcc -O3 or gcc -O2) the
application "freezes" (meaning I don't know what code is still executing)
after the last of my threads (I have three, including the main thread).
This does not happen w/o optimizations.
Cheers

Hello,
I'm looking for information on C# compiler optimization or compilation for
an engineering short paper I want to write. Any sites with some technical
info on the new advances of C# compilation would be greatly appreciated.
Any sites that have comparisons between C# compilation an any other language
would be even better.

Greetings!
Just trying some tests out, and wanted to know about some optimizations.
If I do a CHECK constraint on a table, is this used to optimize a SELECT
or does Postgresql rely mostly on normal index search?
For example, I want to create some tables to manage different data in a
kind of <object, relationship, object2> manner, but where object2 could be
an IP address, text, a number, etc. So I thought of doing the following:

Word up!
If there are any gcc users here, maybe you could help me out. I have a
program and I've tried compiling it with -O2 and -O3 optimization
settings.
The wired thing is that it actually runs faster with -O2 than with -O3,
even though -O3 is a higher optimization setting.
Have I found a bug in gcc? Could I be doing something wrong?

consider the following queries that deals with report pagination
a ) select MYROWS.* from
(select * from TABLE_NAME) MY_ROWS where rownum between 1 and 100
b) select * from TABLE_NAME where rownum between 1 and 100
My question : Does oracle optimize the first query so that it is not
significantly different (on execution time) when compared to the
second query ?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
