I've made the substitution in the code (was line 507 for me-do I have a different version?). Looking at the time chart in Chrome I see that the bulk of the time is for /ipa/session waiting. Would "waiting" mean waiting for the directory server or memcached? Here's a portion of the initial load of the Users page: json/ipa/session POST 200 Success application/json jquery.js:7365 Script 33.94KB 33.10KB 1.57s 1.47s 96ms (1.37s waiting) json/ipa/session POST 200 Success application/json jquery.js:7365 Script 568.09KB 564.36KB 3.92s 2.95s 963ms (2.85s waiting) json/ipa/session POST 200 Success application/json jquery.js:7365 Script 556.94KB 553.40KB 3.78s 2.94s 836ms (2.83s waiting) json/ipa/session POST 200 Success application/json jquery.js:7365 Script 46.93KB 46.38KB 1.87s 1.71s (1.60s waiting) Now, with the pagination turned back on: json/ipa/session POST 200 Success application/json jquery.js:7365 Script 33.94KB 33.10KB 1.58s 1.48s 100ms (1.38s waiting) json/ipa/session POST 200 Success application/json jquery.js:7365 Script 568.09KB 564.36KB 4.05s 3.09s 964ms (2.98s waiting) json/ipa/session POST 200 Success application/json jquery.js:7365 Script 556.94KB 553.40KB 3.84s 2.99s 855ms (2.88s waiting) json/ipa/session POST 200 Success application/json jquery.js:7365 Script 46.93KB 46.38KB 1.52s 1.51s (1.40s waiting) Steve _______________________________________________ Freeipa-users mailing list Freeipa-users@redhat.com https://www.redhat.com/mailman/listinfo/freeipa-users
