[imp] IMP+HORDE: problems of performance

[david at infonet.com.br]

    Hi,


       I have a webmail (HORDE + IMP + TURBA) in which i am having serios problems of 
performance. Monitoring with the command top i visualize that the apache is almost all 
the time using 99.9% of the processor. This server is a really powerful box Compaq, with 
2 processors Intel Xeon 3.0 Ghz, running raid and with like 2048 MB memory, so I think 
it's highly unlikely that this is THAT cpu intensive.  Something is wrong. Are there any 
known bugs out there for such behavior?  
   I am using:

 Red Hat Linux: 8.0 - 2.4.20
 Apache: 2.0.49 + PHP: 4.3.0
 Horde: 3.0-cvs 
 IMP: 4.0-cvs 
 Turba: 2.0-cvs 
 Passwd: 2.1.1-cvs 

                                          Tanks.
