Hello, We have turned on the printing of mem cache statistics using the "logstasts" flag of the pss.cache directive as shown below pss.cache logstats max2cache 33554432 pagesize 33554432 size 17179869184 Can you please explain briefly what is the meaning of the numbers appearing in the corresponding lines of the xrootd log? The following is a common example we see on our xrootd server but it is not clear whether the cache is being effective in this case (we suspect it isn't). Cache: Stats: 0 Read; 38581 Get; 0 Pass; 0 Write; 0 Put; 20 Hits; 3 Miss; 0 pead; 0 HitsPR; 0 MissPR; Path Thanks, George ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the XROOTD-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=XROOTD-L&A=1
