One thing that usually cause this problem
is that the disk access time is slow for the directory where all
the trend files are located. More files in one directory will
increase the access time to that directory. In this case (if all
the trend files are in the same place - 2400 files) Citect has to
wait for the OS to get the access. If there are SCSI discs with
fast access time the maximum number of files you should have in one
directory could be increased.
Experience has shown that if you split the trend files to more
directories this problem will disappear. To give an exact number of
trend files per directory is difficult depending on several
factors. CPU speed, disc speed, type of OS, RAM memory, disk access
per second, CPU load, disc controller, CACHE on disc controller and
so on. To give a hint of the max number of files you should have in
one directory I would say 500 - 1000 files.
