Description

I was trying psklenar setup and the it was slow even if broker received TCP_HIT or TCP_MEM from squid. Some benchmarking show that it take 7 sec between squid get HEAD request and actual response. checking /server-status claimed that the response was procesed within 1 sec (100ms - 900ms), so I think it is either rhn-proxy-redirect problem (because it is between rhn_parent and squid) or problem in peter local setup. I did the same with another sat540 and another rhn proxy and it was very slow too. So its not a setup issue. it is caused by https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=578854, we need to distinguish between HEAD where HEADER_CONTENT_LENGTH is not set by purpose and malformed server which do not send CONTENT_LENGTH on regular request. I will add snippet from proxy_broker.log:
2010/10/20 15:10:36 +02:00 2996 127.0.0.1: proxy/rhnShared._forwardHTTPBody('Response body size: ', -1)
2010/10/20 15:10:49 +02:00 3001 10.34.33.193: proxy/apacheHandler.cleanupHandler
Basically if we try to read body of response from HEAD request, we get lag of 13-15 seconds for every such request.
So we lost during kickstart 2 (first rpm header, then whole package) * number of packages * 15 sec, which is too much (aprox one or two hours)
fixed in spacewalk.git commit 59d7a21b52a3ff52f7d5ff97044b06402dfebf9a cherrypicked to satellite.git as commit 0a387eafec7d5438ccdcf3d46cee07c4e758bd81 Verified. Provisioning over proxy with RHEL5-U5 took 11 minutes, with RHEL6Client 12 minutes. Both, Satellite and Proxy were running on RHEL5-U5 and were located on same network segment. The 5.4.0 RHN Satellite and RHN Proxy release has occurred. This issue has been resolved with this release.
