Hello. Question.. what is the cause of the slowing down of a dig. When dig start I get more than 200 pages/minute and nearly 90 % cpu usage but near the end, I am seeing 20 pages/minute and at most 10% cpu usage. If I fetch the pages from the site being dug at the end, the page comes in very fast ( 100Mb line ) so access to the system is ok. I have set the db cache to 1.3 Gbyte but htdig seems to only use about 260Mbyte. I am putting the databases into /tmp i.e into memory. still plenty of space in memory. du -k /tmp 8 /tmp/.pcmcia 8 /tmp/.X11-unix 8 /tmp/.X11-pipe 8 /tmp/root 8 /tmp/kshroot 8 /tmp/ppp 1351528 /tmp/college 1351624 /tmp here is a top. last pid: 3903; load averages: 0.05, 0.06, 0.07 10:43:05 45 processes: 44 sleeping, 1 on cpu CPU states: 99.2% idle, 0.2% user, 0.6% kernel, 0.0% iowait, 0.0% swap Memory: 2048M real, 351M free, 1613M swap in use, 2029M swap free PID USERNAME THR PRI NICE SIZE RES STATE TIME CPU COMMAND 3607 ppp 1 18 4 265M 263M sleep 762:28 5.17% htdig 3900 ppp 1 58 0 2584K 1704K cpu 0:05 0.15% top 306 root 12 49 0 3472K 2456K sleep 1:54 0.00% mibiisa a -v log ............... 185822:170323:11:http://www.cc.ic.ac.uk/college/onlinedocs/SASOnlineDocV8/sa sdoc/sashtml/gref/zeration.htm: ******* size = 3599 185823:172065:11:http://www.cc.ic.ac.uk/college/onlinedocs/SASOnlineDocV8/sa sdoc/sashtml/accdb/z1258182.htm: ******* size = 3228 185824:172066:11:http://www.cc.ic.ac.uk/college/onlinedocs/SASOnlineDocV8/sa sdoc/sashtml/accdb/z-dbnull.htm: ******* size = 4636 |
