Hi,

Had  2 months of similar pain when moving from 7.5.1.3x up through
7.5.1.86.

Our systems were running as if the site was single threaded and when
certain pages were accessed it would lock up the dllhost process and
the only way to get it back was to kill the process.

We increased the nav manager cache settings (cant remember in which
file, but it was a suggestion from Reddot UK and we dont even use Nav
Man!)  from 25000 up to 75000 and the CMS started allowing multiple
page requests at the same time.  (dont think it was the RDServer.ini,
I think it had main in the name)

We then upgraded to SP2 and the offending pages which were causing RD
to hang would eventually be released and come back unlike the earlier
version.

I would try to find if it is certain pages in the system as it appears
as if the pagebuilder has changed across these versions.   We found
pages which had an anchors referencing lists and removing this brought
back the performance.

Regards,
BjP
