- Still don't know why RSS is so high. 12MB v. IE 2-3 MB
- dprice to look at hot v. cold routines with an eye toward loading less code
- waterson trying to figure out what pages are resident
- Swap in another linux allocator for reduced fragmentation
- kandrot having troubles with what looks like allocator conflicts on SuSE. Redhat Ok.
- Evaluate what's using memory during peak usage on memory hog sites.
- kandrot to look at this
- Examine opportunity for .so and runtime foot print if we can strip exprots and relocations
- cls reports wtc & bryner gave up; only one of the gcc attributes requires glibc support (``protected''); the others just need a modern linker.
- Another thing to follow up on is, can we ``pre-rebase'' Linux .so's to avoid rebasing at load time?
- what is next here? more info on ``magic gcc attributes'' from firstname.lastname@example.org?
- Revisit RTTI bloat issues. gamera is using exceptions which sucks in need for RTTI
- kandrots analysis shows gcc-2.95.2 has 20% higher bloat than egcs-1.1.2
- dont' understand why.

thesteve to fix tools to rollup 'allocation frequency' by functional area to find biggest fragmentation hogs
Examine the Biggest Consumers of Memory for optimized memory use.
- Image Lib - saari/pnunn - image cache redesign work landing late feb.
- Images are ~20-30% of live object data according to trace malloc reports.
- Largest speed deltas are also on intensive image pages.
- pav, tor - found optimization that allows storage of image bits only on x-server
- evaluting ways to decode to 16 bits on 16bit systems
- empty/spacer images need to be compressed
- Style System - pierre/attanasi -
- look at factoring options
- pierre's latest enabling changes regressed performance. evaluating
- about a 70% space reduction in memory use for sytle rules might be achieveable

- Gotta figure out why those memcache entries are porkin' up. Can
we do a quick hack while we're waiting for the New New Cache?
- What's all that `void*' stuff? Need to tweak the stack
http://bugzilla.mozilla.org/show_bug.cgi?id=66691 for then HTTPHandler-related growth
- nsStrings? nsVoidArrays? From where?
- 331 new nsHTTPChannel objects. Wow! Why do we have so many
of these lying around? http://bugzilla.mozilla.org/show_bug.cgi?id=66694
