Eric,
Thank you for taking your time to offer your sound advice. We are running ListServ 16.0 Build Date 13May2014 on a Windows 2012R2 64bit OS virtual server with
8GB virtual memory and 4 - 2.67GHZ virtual processors.
Could you please tell me how I can verify if we are or are not running the high performance option? I ask because I found the first three variables in the current
configuration without values and a DBRINDEX setting that is currently “undefined”. However, I am unable to locate the DBRINDEX_CACHE or MAX_OPEN_ARCHIVE_FILES variables in the current configuration. And if we are not running the HPO option, should we consider
doing so and how?
Thank you,
Janice

Try these settings on a 23 July 2012 or later HPO build:
FIOC_TARGET=1000000
FIOC_TRIM=1050000
FIOC_WARNING=1100000
DBRINDEX_CACHE=250000
MAX_OPEN_ARCHIVE_FILES=50
This assumes you have a 64-bit operating system with at least 1GB of unused RAM, which is usually the case on physical servers, but you may need to increase the
RAM quota if you use a VM. You may also have to increase process open file quotas. The first search after you restart LISTSERV may still be slow, but from then on you should see a big improvement.
I think we got rid of our last non-VM production instance around two years ago, but you do have to be careful with the VM settings, and in particular the RAM,
which we allocate generously in our production environment. I don’t mean that LISTSERV needs a huge amount of RAM, I just mean that one usually allocates RAM conservatively in virtual machines and with LISTSERV HPO this can have a big impact.

I am the Listserv Admin from Dept. of Energy. I run our Listserv server in a Linux VM on VMWare. We are experiencing the same problem. Since I do not have that
much of a customer workload on the server, I have set a cron event to recycle the Listserv process every 15 minutes.

Subject: [LSTSRV-L] Advise on tuning please
Hello,
I manage the ListServ for the NIH. Our ListServ server is running in a VMWare virtual environment. We have recently experienced extensive searches that have
negatively impacted the ListSev service. The end result is users unable to authenticate to ListServ. A reboot quickly resolves the issue. Has anyone tackled this issue successfully? I was wondering if the tuning options would help but I was unable to find
information on LSoft’s support site.
Any information and/or advice is greatly appreciated.
Thank you,
Janice Crum
