Aleph OPAC response time is slow.
Check the Oracle indexes for the Bib, ADM, and HOL libraries with the all_indexes SQL, as described in " How to tell if Oracle indexes for a particular library are present & VALID ".
Check tab_base.lng for severe truncation, as described in the article " Logical base response very slow ".
See if searches on common words with many hits take longer than other searches. If so, see article " Keyword searching on common words takes extremely long; multiple z97's "
grep the OUT lines in the www_server_499n.log into a file grep.www.out (these include every time the OPAC user hits Enter):
>grep OUT www_server_4991.log > wwwOUTgrep
Then do greps of this wwwOUTgrep file to analyze the numbers of transaction responses in specific time ranges (seconds):
aleph@aio0001(a23_1):~/a23_1/log>grep -c 'OUT 0.' wwwOUTgrep
aleph@aio0001(a23_1):~/a23_1/log>grep -c 'OUT 1.' wwwOUTgrep
aleph@aio0001(a23_1):~/a23_1/log>grep -c 'OUT 2.' wwwOUTgrep
aleph@aio0001(a23_1):~/a23_1/log>grep -c 'OUT 3.' wwwOUTgrep
If greps show that almost all of the times are ten seconds or less and you are seeing much longer response times, it could be a communication issue. Please consult the article ELAPSED-TIME" in pc_server logs and actual response time in this regard.
