Hi, there were disscution in our old forum about nf speed increasing. But now we can see only new topic. How many Ram (nf server cache) we need for normal work. Server is PII, database - 1.2GB. Thanks in advance RGDS Gedas
NF server used cache is ~50% of RAM. For RAM calculation I’m use formula: RAMsize = maxTableDataUsedSize * 1.2; //for high perfomance RAMsize = maxSessions * 5 Mb; //non-stoned work Next step to incrace speed a lot of SCSI HDD’s.
Dalius, is 1.2 a constant or is it 1.2 because the dbf is 1.2GB? I assume the second line in your formula should read: RAMsize = RAMsize + (maxSessions * 5MB); Dennis van Es PerCom: Research & Development BV The Netherlands
sorry, second line must be read: NFserverRAMusage = maxSessions * 5 Mb; //non-stoned work this formula good then a lot of sessions will be used in big database. 1.2 is not 1.2 Gb there is + 20%. I perceived that then table size grow up this size, prerformance considerable slow down & downing stops then AverageTableSize > RAMsize * 0.8; AverageTablesize - mostly used tables 17,21,32… Then your server will be as speed as HDD speed are.
