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
