Using a clean and updated install of Debian testing (Sarge)
----------------------------------
I'm setting up a mod_perl server, running OpenInteract2, with LDAP in use.
Having a look at what Apache::Status has to say about memory usage (using B::TerseSize, and enabling the StatusTerseSizeMainSummary and StatusTerseSize features) I notice that Convert::ASN1::parser and Convert::AS1 both are quite memory hungry:
File::Find 2127256 bytes | 3630 OPs
Convert::ASN1::parser 1218845 bytes | 3356 OPs
File::Copy 657597 bytes | 2805 OPs
Convert::ASN1 570976 bytes | 7701 OPs
OpenInteract2::Action::Page 468196 bytes | 4991 OPs
(I removed some of the B::* modules for clarity)
Inspecting Convert::ASN1::parser, I find that the following methods are listed on top:
yyparse 84342 bytes | 1859 OPs
compile_one 22327 bytes | 514 OPs
yylex 11147 bytes | 201 OPs
verify 10008 bytes | 245 OPs
expand_ops 8405 bytes | 181 OPs
Can the Convert::ASN modules be made less memory intensive?
