           Summary: RSSyl generates too much IO
           Product: Claws Mail
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Plugins/RSSyl
        AssignedTo: users at lists.claws-mail.org
        ReportedBy: higuita at gmx.net


i have setup RSS feeds for slashdot and freshmeat/freecode and as they have
high volume of changes and i dont expire old news, their folders have ~10.000
items.

When RSSyl tries to fetch/update the feed, the machine load jumps to ~50 and i
can see high IO requests from claws. Trying to check what is happening i get
this:
write(1, "feed.c:911:", 11)             = 11
write(1, "Appending 'Greg KH Leaves SUSE F"..., 53) = 53
write(1, "feed.c:909:", 11)             = 11
write(1, "RSSyl: starting to parse '42143'"..., 33) = 33
write(1, "feed.c:662:", 11)             = 11
write(1, "RSSyl: parsing '/home/higuita/.c"..., 64) = 64
open("/home/higuita/.claws-mail/RSSyl/Slashdot/42143", O_RDONLY) = 31
fstat(31, {st_mode=S_IFREG|0600, st_size=3859, ...}) = 0
read(31, "Date: Sun, 19 Feb 2012 20:11:00 "..., 3859) = 3859
close(31)                               = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3439, ...}) = 0
write(1, "feed.c:719:", 11)             = 11
write(1, "RSSyl: got date \n", 17)      = 17
write(1, "feed.c:712:", 11)             = 11
write(1, "RSSyl: got author 'samzenpus'\n", 30) = 30
write(1, "feed.c:725:", 11)             = 11
write(1, "RSSyl: got title 'Canada's Onlin"..., 84) = 84
write(1, "feed.c:768:", 11)             = 11
write(1, "RSSyl: updated title to 'Canada'"..., 100) = 100
write(1, "feed.c:732:", 11)             = 11

write(1, "RSSyl: finished parsing headers\n", 32) = 32
write(1, "feed.c:789:", 11)             = 11
write(1, "Leading html tag found at line 1"..., 34) = 34
write(1, "feed.c:796:", 11)             = 11
write(1, "Trailing html tag found at line "..., 35) = 35
write(1, "feed.c:911:", 11)             = 11
write(1, "Appending 'Canada's Online Surve"..., 86) = 86
write(1, "feed.c:909:", 11)             = 11
write(1, "RSSyl: starting to parse '43813'"..., 33) = 33
write(1, "feed.c:662:", 11)             = 11
write(1, "RSSyl: parsing '/home/higuita/.c"..., 64) = 64
open("/home/higuita/.claws-mail/RSSyl/Slashdot/43813", O_RDONLY) = 31
fstat(31, {st_mode=S_IFREG|0600, st_size=3829, ...}) = 0
read(31, "Date: Tue,  3 Apr 2012 18:31:00 "..., 3829) = 3829
close(31)                               = 0
stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3439, ...}) = 0
write(1, "feed.c:719:", 11)             = 11
write(1, "RSSyl: got date \n", 17)      = 17
write(1, "feed.c:712:", 11)             = 11
write(1, "RSSyl: got author 'samzenpus'\n", 30) = 30

So looks that RSSyk is trying to read ALL the items on those folders. So the
more items we have, the more this is a issue
