First of all...

MV b326
MVP b295
CB #1337
PEX 1.15

Disabled most plugins and found the culprit to be MultiVerse. Running 3 worlds with 1,5GB ram dedicated for Java and Minecraft.

On join, after the "logging in..." message comes "Downloading terrain...", it stays there for 5 seconds or more, which causes notable lag for other players.

For testing, I disabled keep spawn in memory for all worlds. No luck. Removed temporarily all other worlds and left mainworld in there, reloaded MV and still no luck.

Disabled MultiVerse completely and restarted. Notable increase in joining.

And here are some specs from the server:

Dual Hexcore Intel Xeon 7460
8x 16GB DDR3 RAM (yes that's 128GB RAM)
4x 1TB harddrives in RAID10
100MB connection

Although, at time of testing, CPU usage was a total of 81,7% and free RAM only 337MB.
