Hi all.
Sorry if it's a question that you have always see, but i'm not able to look
at the archives ...
I'm using JCS in an application where i need to look 1600 time on the cache
in a loop.
The cache is empty at this time.
For loop take about 160 seconds.
Using hashtable instead of JCS take a
No, no one has ever asked if JCS is slow. Something is definitely
wrong. The cache is not significantly slower than a hashtable. Can you
give more details about your configuration (i.e. the cache.ccf file) and
what you are caching.

I am caching String (key) for Vector (value) ...
But I found somethings. Y have a disk cache. By disable it, I can improved
my speed when cache is empty. But if I fill cache with 1600 items, it take
about 1 min for looking for 100 items inside :(
Here is my cache.cff file, the code follow ...

I'm not sure what is going on. Are you getting any errors in the logs?
Your test will be off if you call the slow Date(), over and over again
in System.out.println (new Date ()); You should use the system
currenttimemillis.
Alos, you might want to use an ArrayList rather than a vector here.
It looks like your memory caches are bounded at 1000 items (MaxObjects
= 1000). Thus if you put 1600 items in the cache, and then look for any
of the first 600 items, the cache will need to read them from disk,
which takes time.

I have no message in log.
I going 2 time in this method. First time the cache is empty and i'm comming
with 1600 element, wich was stored un the cache, and the second time with
5500 elements. It's the second time the slowest one (1m/100 elements).
I have the tmp file with (about 4Mo).
Here is my
But I have 8 line in log for each element read :
Maybe it's comming from here ? How can I disable the log ? Is it maybe
JBoss
who activate this ?
Oh my yes, 8 lines of output per element will slow things down plenty.
You need to turn the log4j log level for the jcs classes up to INFO or
WARN. Ye
The log4j configuration in JBoss can be done at
$JBOSS_HOME/server//config/log4j.xml , for most of the jboss
3.x series. If you are using some other profile rather than "default",
replace accordingly in above.

I have do many thinks.
In log4j.xml :
So, no more loging in file. (I have look on the file, and there is nothing)
In my class :
try
{
JCS cache = JCS.getInstance("Test");
System.out.println ("Before test");
c
Running the same test as standalone in a main :
