Description _ rkubacki 2004-07-20 16:26:39 UTC 
MdrStorage.getContextAssocEndIndexName produces
highly ineffective names used as a keys for a
hashtable references from NameIndex. They typicaly
look like:
ae:1CCBE232-D0DE-11D8-ACAD-208A06A3AA77:000000000000008C:1CCBE232-D0DE-11D8-ACAD-208A06A3AA77:00000000000000931

It means that they contains twice the same
storageId  as a part of MofId string represantion.
I found 460 instances if these String in my IDE
(nb20040719) with two projects opened containg 6
files running on JDK1.5.0b55. Each one is 112
characters so we have more than 100kB occupied by
them.

Probably we can squeeze them significantly.

Comment 2 _ rkubacki 2004-07-22 11:08:01 UTC 
Thanks, now they are 472 string with values like 'ae:2183:2195:2'

Perhaps you can fix also other indexes. Although it is not big benefit
now it will not cause creating of string version of mofid for them.

34 instances of
ai:4AD8D42A-DBBE-11D8-8F69-963C2051AA77:0000000000000EB3:Java.Resource.name
21 insatnces of aibn:4778E02A-DBBE-11D8-8F69-963C2051AA77:0000000000000B0A
21 instances of aicp:4778E02A-DBBE-11D8-8F69-963C2051AA77:0000000000000B0A

Number of instances depends on numbers of classpath entries I guess.
Comment 3 Martin Matula 2004-07-22 11:46:14 UTC 
You are right. Now it is fixed.
