I've detected some slowness in Firefox 17 under Fedora 18, so I decided to modify some configuration options.So, the question is: Does someone know if the maximum value of network.http.pipelining.maxrequests is still 8?I find people saying that if I put more than 8, it will be ignored. It seems weird to me that the default value of Fedora and also Centos is 32.
Is the maximinm value of network.http.pipelining.maxrequests still 8?
fedora;centos;firefox
I don't think so.  The discussions for this from 2010 refer to an annotated  #define from nsHttp.h in the Mozilla CVS tree:// hard upper limit on the number of requests that can be pipelined#define NS_HTTP_MAX_PIPELINED_REQUESTS 8 However, apparently, For Gecko, XULRunner, and Firefox, CVS trunk is no longer the trunk, and is instead used for Gecko 1.9 / Firefox 3 and the 1.9.0.* / 3.0.* security releases.  The corresponding file in the current mozilla-release branch (which I presume includes 17, and it is the same as the -esr17 branch) does not have that define, and that identifier does not appear in the release tree at all.  The actual variable that's set here using the enum name (MAX_PIPELINED_REQUESTS) from nsHttp.h is mMaxPipelinedRequests, and looking at the other references to that, its only restriction would seem to be that it's an unsigned 16-bit value, meaning it has a range of 0-65535.
