I'm not seeing a hit on 'next'. A quick "just pound on 'next' and watch the
|
|
wall clock" test shows me able to go through 20 messages in under 5 seconds,
|
|
so it's well under 250ms per switch, but I'm seeing a really piggy CPU spike
|
|
(100% for a few seconds) in the 'flist' code. Of course, it seems to be
|
|
related to number-of-folders:
|
|
|
|
[~] wc Mail/.folders
|
|
131 131 1122 Mail/.folders
|
|
|
|
It's particularly annoying because things just hose-and-hang for 10 seconds, so
|
|
when it hits, you have a long latency before what you're doing actually
|
|
happens...

14:11:03 Flist_FindSeqs reset=0

|

14:11:12 Flist_Done
|
|
14:11:12 Flist_FindSeqs end {9018315 microseconds per iteration}
|
|
|
|
I'm perfectly willing to can-opener that code and see where the CPU is
|
|
going, but only if nobody is slapping their forehead and mumbling about
|
|
a brown-paper-bag bug... ;)
