Comment #1 on issue 2474 by [email protected]: Investigate use of
__thread for faster TLS on glibc
http://code.google.com/p/v8/issues/detail?id=2474
The vast majority of TLS accesses in v8 is caused by trying to conjure up
the current Isolate. We already worked on reducing this internally (and we
should probably go a bit further there), but a big step towards fewer TLS
accesses will be changing the external v8 API to *require* an explicit
Isolate in all places where one is needed.
We plan to go into that direction in Q1 already, and we think this route is
more promising than trying to reduce the cost of the access itself.
