[platform-dev] Parallel index search merged for 4.19 M1
|
Hi all,
we've submitted a change to JDT index search that would try to parallelize index search (available since build I20201231-1800).
This feature is turned *on by default* in 4.19 M1, we might keep it enabled for the final release, or switch it off - depending on the feedback.
We expect a decent search performance improvement for large workspaces, in various scenarios up to 2x - 6x, depending on available hardware.
We also may see some regressions because adopting old & complex single-threaded code to a multi-threaded scenario is a not trivial challenge.
Therefore it is possible to switch new parallel index search off by disabling new "Preferences -> Java -> [] Enable parallel index search" option.
In case you see some unexpected Java search results (also visible via content assist, Hierarchy view etc), too slow search, too less or wrong search results or even errors, and *they don't appear* with *disabled* parallel index search, please report this on bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=567521.
Kind regards,
Andrey Loskutov
