Sinatica uses really strange terms to describe transactions behaviour, and
since it is an abandonen tool, nobody can explain how they are aligned with
real situation.

From our optimization practice we found that if you need to optimize
only the single instance of the database, the most cost effective way is
to upgrade to SSD first, and only then fix other problems.

, this idea is not so good as it appears - if index has good
selectivity, Firebird usually uses it very effectively, until you have
some abandoned parts in the database, where you never send SQL queries.

Hi,
Gfix visits each page of the database, so 90 minutes is not so long if
your disk subsystem is not based SSD.
In general, follow these steps

MonLogger saves all data from MON% tables for the investigation in the

transactions which are potentially conflict, so you can review which
application runs it.

There should a reason why optimizer chooses the wrong plan.
Try to recalculate indices statistics.
Also, for general performance, use optimized Firebird configuration:

Hi Eduardo,

I searched in Google and found that, for instance, MS suggests not to
install SQL Server in a domain controller, but for security reasons.
In some articles, MS even recommends to disable disk write
that cache is bad, just highlights the potential risk
of data loss if caching without BBU is used.
So, essentially you need to buy advanced disk controller and properly
setup it - that's true.

stability comparisons.
Thanks.

Firebird to preserve versions of updated record.
In general, avoid multiple updates of the same record - replace them
with INSERTs and some scheduled delete, right before sweep.
