Re: [sqlite] Strange index creation/insertion performance between Windows and Linux 64-bit

Thanks for the replies. - All insertions are within a transaction - Database was originally created on Linux (with a 1K page size) and copied to Windows - Changing the page size to 4K (and vacuuming) lowered the index creation time on Windows to 50 seconds and on Linux to 5.5 minutes.

and the insertion speed seems fairly constant. Can anyone offer any explanations for these huge disparities in sqlite performance on these two platforms? And why Windows does badly on index insertions and well on rebuilding it from scratch, and Linux 64-bit has the exact opposite behavior? Brian

2009-05-26 Thread Brian Dantes
We've run into an alignment issue in SQLite 3.6.14.2 which only seems to cause a problem under Solaris Sparc in our testing. Failure narrowed down to: src/rowset.c:186 pEntry->v = rowid pEntry is 0xX4 __alignof(*pEntry) is 8 (because of an i64) However sizeof(RowSet) is 28 (and 28%8 = 4),
