I notice that in some casual circumstances, 4D client of my application,
have latency in the front end operations.
I click, but the client is not responsive.
After some seconds or one minute, all restart normally.
I've noticed that before the unlock, I have one peak of traffic in the
network. Seem that the client is stopped to wait for the server response.
Does someone have a suggestion?
Thanks
Ferdinando

As Chuck pointed out, you may need to increase the size of your cache. The Info
Report will make this evident.

Hi Tom,
How I can find this component?
Thanks

That is the default and should work pretty well. You may be suffering from a
related condition informally known as “cache thrashing” which was not uncommon
in 4D v13 (as well as some later versions, but I haven’t kept up on what
progress has been made).
If you aren’t already using it, you can monitor cache performance with the 4D
Info Report component, available from 4D Tech Support. It can show you
graphically where the long cache flushing occurs.

What is the “Flush Cache every..” value in Database Settings>Memory? If there
are ‘lots’ of records being flushed, sometimes that can take a while. Setting the
value smaller causes it to happen more frequently, but fewer records, which can be
more efficient.

Hi All,
In one my application in 4D V13.4 on Windows, in some circumstances 4D client
freezes, seems when in one process he must to write more records.
During these freezes periods, the 3/4 processes launched from my applications
work, but the front end interface is locked and is not responsive.
After some seconds or minutes, 4D client work normally. Is possibile that this
is because he must to write more records ( i think around 100 - 300 records )?
Is necessary to use FLUSH BUFFER commands?
Thanks
Ferdinando
