Normally while reading a file, glusterfs (fuse) get following calls from VFS, lookup, open, read, . . . read, flush, close. But quick-read exploits an internal feature of glusterfs present in lookup to get the entire file in lookup call itself. Hence open, read and close calls are short-cut at quick-read itself and they don't reach server thereby saving 3 transactions over network (probably more due to read). > > Ian > > > On 23/03/2010 05:26, Raghavendra G wrote: > > read it as "Also note that" > > On Tue, Mar 23, 2010 at 9:25 AM, Raghavendra G <raghavendra at gluster.com>wrote: > >> Also not that with quick-read there is an issue with memory consumption, >> which will be fixed shortly. >> http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=723 >> >> >> On Tue, Mar 23, 2010 at 9:21 AM, Raghavendra G <raghavendra at gluster.com>wrote: >> >>> Hi Ian, >>> >>> Try using quick-read for glusterfs, if you are planning to use apache. >>> >>> regards, >>> On Mon, Mar 22, 2010 at 6:21 PM, Ian Rogers < >>> ian.rogers at contactclean.com> wrote: >>> >>>> On 22/03/2010 13:59, sac wrote: >>>> >>>>> Hello Ian, >>>>> >>>>> >>>>> On Mon, Mar 22, 2010 at 7:07 PM, Ian Rogers < >>>>> ian.rogers at contactclean.com <mailto:ian.rogers at contactclean.com>> >>>>> wrote: >>>>> >>>>> >>>>> Is mod_glusterfs still recommended for apache servers? >>>>> >>>>> This message - >>>>> http://www.mail-archive.com/gluster-devel at nongnu.org/msg06304.html >>>>> - suggests that mod_glusterfs would be replaced with booster, but >>>>> I've also seen that booster is now deprecated... >>>>> >>>>> >>>>> mod_glusterfs is no longer supported or maintained.
