Killed IVP6 (browser and system level)- Helped a bit

Perhaps then your provider is an issue.

Could very well be, but if I can make progress locally, it tells me that the
problems are most probably mine. I believe that IPV6 packets proceed IPV4
packets, so the rejection of data must take time.


Turned off firewall - Helped a lot

Strange, as that would only matter if there is an enourmous amount of
traffic. And with enourmous, I am talking about more then your household
connection could handle.

My idea here was to clear the pipe and go from there. Certainly if I am
producing and receiving a lot of packets, turning off the firewall should
make a difference. I guess another question would be if Virtuoso is sending
information out and getting a response? Nast shows me a lot of headers, but
I haven't checked it lately, nor am I really sure what I am looking for.



Went to only DCHP4 - That helped

Also strange as that only matters when the connection is set up.

This is when I was investigating possible conflicts in DNS. Seemed to work,
though I agree its strange.


Then went to investigate CPU and memory. Found that Firefox is taking
161mb of memory, while Chrome looks at each page ass a process and adds
up close to that. CPU cores were both at 100%, very little swap going
on.

Memory is there to be used. 161MB is not that much and as there is no
wap used, it should be considerd normal.

Agree


Then I

Changed the Hardock from default @256 to @512 - this made things a bit
zippyer overall

What is hardock?

This limits the size of the memory that a single process may lock in
physical memory (thus preventing it to be swapped out). The default is set
at 256K. Seemed to make everything work better.


Then I looked at the processes and noticed that Virtuoso was gobbling
CPU. Killed it, and now things are running semi smoothily. As I
understand it, Virtuoso does a lot of indexing control? What is the
best way to fix this problem and how much am I risking for more
trouble?

Interesting. I get this, but how do I do the re-index after? Do I really
need to?
