While on the subject of bge any idea why it performs so poorly in 100Mb mode
when compared to the humble fxp in the following results.

<quote=Why is MySQL nearly.....>
FreeBSD 5.1.2 (i386)
local: 22834.872368421 records per second
fxp 100Mb: 3854.06863517 records per second
bge 100Mb: 2501.66999862 records per second
bge 1Gb: 3281.65229885 records per second
</quote>

Connection is TCP based with fairly small packets but at high volumes
fxp was pushing 4k packets / s where bge would only do around 2.5k
