Hi all,

I'm been running basex on two environments, one is my laptop with an SSD drive and ext4, the other is a server with raid-1 HDD and ext3.

Using iotop, I am watching the disk access of the server and laptop, and comparing the two.

After some update queries, I notice that the server (ext3) has a process, [kjournald], which writes for about 20 seconds at 600-1000KB/sec.  This only begins after the update is complete and the java process actually stops writing.  I am not experiencing such a thing on my laptop.  If I do too many of these queries on the server, it will eventually hang for 20-30 seconds.

I've copied the exact data on both the laptop and the server.

Are there any recommended filesystem types for basex?  Does it sound like I've configured something incorrectly, or should I add some more drives to my server and have them using ext4?  Or is the difference SSD vs HDD?  I never saw my SSD write speed go above 200KB/sec or so during the same queries.

Any help would be greatly appreciated!
