Windows .jar server can't keep up

[shadowfirelord]

hey all

ive been playing my own server for a few weeks but since today the server started crashing and giving the message [WARNING] Can't keep up! Did the system time change, or is the server overloaded?
nothing changed , other then more floors done off my soon to be factory building.
there is almost no machines running just my me storage and a quarry

spec-wise my pc is more then strong enough to play and host imo.
i7 3930k 64g ram 256ssd+multiple TB hds titan sli

i've had a previous server that had the same problem
even though the server is running on 6g ram and client is aswel

i would love to c this fixed so that i can fining my 151*151*75 structure
but everything i found sofar on this and other forums was of no use

edit : using ftb ultimate

all input is welcome

Have you tried adding the jvm arguments to both the client and server from the link below. Running a modded minecraft server from the same system will put extra load on any system.

Just did a bit of math. Not counting a roof, that's over 181 thousand microblocks. This is probably your problem. I've seen people have performance issues with a couple thousand microblocks.

My suggestion is to use microblocks as accents, not as building materials.

lighting the whole place isnt rly what i wanne do since i loose room for th things i wanne do in there

If you want to do go the half-slab method of preventing mob spawning, use the "vanilla" method of making the slabs, not the FMP method.

sadly that does not work for marble
