Yep, as I said I basically had saw big slow downs during Node's insertion using the "Big Transaction" pattern as soon as the DB grow in size o in Node's number. I'm trying to populate the DB with Nodes with only one String property, an IPv4 address. This is just a test case for my typical use case and it shows that when the process starts the first 440744 nodes are going in at a speed of 1.05ms each Node but this speed drops to 8.75ms after having inserted 12545155 nodes. The final DB size is: 2.9G since i tweaked the sintrg_block_size at graphdb creation time to 60bytes instead of 120... The box is a CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (2993.02-MHz 686-class CPU) with 2G RAM of which 1.5 are dedicated to the JVM process: -Djava.awt.headless=true -Xms40m -Xmx1536m -XX:+UseConcMarkSweepGC Have you any clue?
