Hi Hatton
The k2server that ships with 6.1 and prior (cf5) uses a lot of ram, but it is
easy to predict and it does not grow. I don't know if this will help with
understanding whatever it is that ships with cf7, but here goes:
Each "worker thread" allocates about 4.6 MB of memory. Each collection has a
worker thread pool that has "numThreads" worker threads. In the k2server that I
use, the numThreads is in the k2server.ini file, which I guess they got rid of
in cf7. Anyway, NumCollections * NumThreads * 4.6 MB = total virtual ram used
by k2server.exe, and it will hit this size as soon as it starts up (assuming
the collections are configured to be "online"). The number of docs in the
collection doesn't matter at all.
Using this info (which I derived experimentally), I was able to reduce the
memory usage or our k2server by a lot, mostly by excluding collections I didn't
really need and by reducing numThreads to something more in line with what I
needed.
Does this make any sense from the point of view of the new k2? I'd sure like
to know if they changed something.
Thanks
Mark

Subject: Verity Process Comparison 6.1 -vs- 7.0?
I'm working with a hosting company to see if they'll take the pluge to
upgrade to CFMX 7. They've gone so far as to download an eval version
and put it on a server to watch how it acts in their hosting
environemt. The admin has expressed a concern on the memory usage for
the "search engine" (aka Verity).
My question - did any big changes get made to Verity for CFMX7 and
does anyone have a side-by-side comparison of processor/thread/memory
usage between the two versions?
Thanks!
Hatton
