Bug#810898: apt: "apt-get update" (1.2) very slow with compressed indices and debtags
Hi,
Enrico Zini made this python3 code to test the problem outside debtags:
#!/usr/bin/python3
import apt
def main():
cache = apt.Cache()
for pkg in cache:
cand = pkg.candidate
if not cand: continue
tags = cand.record.get("Tag", None)
if not tags: continue
print(pkg.name, tags)
if __name__ == "__main__":
main()
Running it without compressed index in apt:
# time python3 cattags >/dev/null
real 0m1.671s
user 0m1.539s
sys 0m0.132s
with compressed index:
# time python3 cattags >/dev/null
real 1m44.238s
user 1m33.536s
sys 0m10.698s
I'm going to re-assign the bug to python-apt, maybe they have more info
on the issue.
Bye
E.
