Deprecated - Performance and scalability

I am doing a migration of a community website over to Drupal and have come up against a problem that does not seem solvable. The amount of users and nodes is too large for the Watchdog and the Cache queries. It seems that upon logging on that the creation of the user menu to cache and the watchdog exceeds the MySQL max_allowed_packets. Thus the watchdog table cannot be locked. The same applies to the cache table.

Besides sitting a tinkering with MySQL is this something that has been addressed in later versions of Drupal? Does 5.x or 6.x suffer from the same failing?

I have MAMP running on my local testing server and I opened a backup of my actual site onto it (all databases and files)... It works perfect in browser, but when I try to run Apache Bench I have problems

No matter what URL (Drupal Clean, Path Clean or simply unclean) I use for any of my drupal pages I am always returned a "Test aborted after 10 failures" message.

On the other hand, any single page of my Vbulletin forum, even ones with arguments in the URL works perfectly...

Whats going on, what am i doing wrong?!

Uploaded files all stored in one folder is ok but it will become VERY slow when the amount of file increases. If there are like over 10000 files(likely), it's better to seprate into into different folders.

is there a setting in the Drupal core? or is there a module for this? is this function going to be part of Drupal 6?

I have installed the pdfview and other needed files. And it is working. There is only one little problem when it render a node to pdf the text does not enter to the next line if it exceeds the right side of the page. It reaches far beyond the right margin of the PDF that is why some text are not visible.

Help me please.

Thanks you very much...

I am new to Drupal and need to know if anyone knows if Drupal 5.2 can run on a Windows 2003 server, IIS 6.0 at 64 bit?

So, to give you an idea of what kind of performance, Caucho's site claims 4x improvements over standard mod_php with many applications, including Drupal. So, we decided to use some of the machines in our lab to try this out. Seems like a good idea, no? And a drum roll please... Well, I'll be damned if they weren't correct. Here are the results:
