In Oct-Nov 1991, I found that compiled code saved 30% CPU time. After checking with Eric on a few points, I manually recompile updated EXEC code for each new release. What to compile for release 1.7c: LSVPROF and LSVALLOW LSVDBASE LSVDIST2 LSVSHOW LSVBLC LSVDBBN LSVMAIL LSVXMAIL LSVBSE LSVDBLS LSVOWN LSVXSTAT LSVCKB LSVDBNB LSVREACC LSV82I LSVDACC LSVDBUDD LSVRECV This list was made from three groups: - LSVPROF This is needed as Eric said for determining compiled code or not. - all EXECs listed via CMS EXECMAP on the server (these are EXECLOADed for a reason!). NOTE: LSVINTPT will not compile. - all database EXECs (fn=LSVDBxxx) listed via CMS EXECMAP on the server *after* a database command. This will speed up database searches. NOTE: LSVDBPN will not compile. Don't forget to up your server's default virtual storage by 2M. It seems to be worth the 30% cpu reduction for us. We are a backbone site with a few active lists. I also agree that PREXX code will probably make compiling less effective in the future; however, some key EXECs like LSVDIST2, LSVMAIL and LSVXMAIL can make a big difference now. Gary P.S. There were 3 sites running compiled code only 11 months ago. Harry reports 6 sites now. I think more Listserv sites will be looking for ways to lower cpu consumption these days... ;-)
