Here is ab sending a test to an LVS server in front of a 3 node web server. The average loads on each server was around 8.00 to 10.00. These aren't very good numbers and I'm wondering where to start looking. These are pretty much default apache RPM versions out of the box. # ab -kc 50 -t 30 http://192.168.1.150/ This is ApacheBench, Version 2.0.41-dev <$Revision: 1.141 $> apache-2.0 Copyright (c) 1996 Adam Twiss, Zeus Technology Ltd, http://www.zeustech.net/ Copyright (c) 1998-2002 The Apache Software Foundation, http://www.apache.org/ Benchmarking 192.168.1.150 (be patient) Finished 130 requests Server Software: Apache Server Hostname: 192.168.1.150 Server Port: 80 Document Path: / Document Length: 8997 bytes Concurrency Level: 50 Time taken for tests: 30.234185 seconds Complete requests: 130 Failed requests: 0 Write errors: 0 Keep-Alive requests: 0 Total transferred: 1371090 bytes HTML transferred: 1299586 bytes Requests per second: 4.30 [#/sec] (mean) Time per request: 11628.532 [ms] (mean) Time per request: 232.571 [ms] (mean, across all concurrent requests) Transfer rate: 44.25 [Kbytes/sec] received Connection Times (ms) min mean[+/-sd] median max Connect: 0 1 1.4 2 4 Processing: 409 6228 4357.5 5227 16317 Waiting: 369 6146 4370.8 5199 16261 Total: 409 6230 4358.1 5230 16321 Percentage of the requests served within a certain time (ms) 50% 5230 66% 8331 75% 9310 80% 10386 90% 12820 95% 14502 98% 15399 99% 15746 100% 16321 (longest request) -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
