MagmaCollectionReader>>size takea a long time

[Burella Juan M.]

Hi list,

      I have a indexed MagmaCollection ( it has about 11,000 objects). I
have noticed that requesting the size to a MagmaCollectionReader takes a
long time whereas the same requesting to a MagmaCollection doesn´t

 For example:

"MagmaCollection>>size - fiirst evaluation"
[ (magmaSession root at: #Serial) size ] timeToRun  "answer about 525
milliseconds"
"Note: magmaSession root at: #Serial answer a MagmaCollection"

 "second evaluation"
[ (magmaSession root at: #Serial) size ] timeToRun  "answer about
1milliseconds"

"MagmaCollectionReader>>size  first evaluation"
[ ((magmaSession root at: #Serial) read: #issnString) size ] timeToRun
"answer about 9798 milliseconds"
 "second evaluation"
[ ((magmaSession root at: #Serial) read: #issnString) size ] timeToRun
"answer about  8992 milliseconds"

Any suggestions for reducing this time?

Thanks in advance.
Juan Matias.
