Understanding barrier on Linux
It is known that massive write operations in Firebird databases (like updates affecting thousands or millions of records) had become much slower in more recent Linux servers. After investigation, I found this to be related with the fact that most recent distros brings the barrier parameter of the filesystem activated.
Unfortunately, I wasn’t able to solve this “problem” completely, without opening a door for corruption. The slow down when barrier is enabled can be minimized a lot if the database is configured with forced writes OFF, but this also may lead into corruption if something bad happens to the server.
Anyway, the purpose of this post is to share an article that helps to understand how barrier works and why it slow down such kind of operations.

More than R$ 4.000 donated for protocol performance enhancement
Many attendees of the 9th Firebird Developers Day donated money to sponsor the enhancement of the Firebird protocol, known to be “slow” in high latency networks (ie: internet). This is the #1 voted feature in the Firebird tracker! The development will be done by Dmitry Yemanov, chief of the Firebird development team, and available in Firebird 3 (with chances of being partially backported to Firebird 2.5.x). A list with the names of all donors and values can be found here.

Project: Firebird Core
Issue Type: Task
Components: Build Issues / Porting
Affects Versions: 2.1.5
Environment: Android 4
Reporter: JLM
Priority: MinorHello,
I’m trying to build Firebird 2.1 for Android ARM.
For the moment, I am compiling, step by step, by correcting builds issues.
To compile, I use the custom NDK R7 by Crystax in order to use the standard libc instead of the Bionic libc.I will write my advance gradually.
Regards,
Loweno
