Nevertheless, I cannot reproduce this issue even with
Acquire::GzipIndexes enabled. Both commands (markauto and
forbid-version see as fast as before:

# time aptitude markauto 1234
No such package "1234"                   

real    0m1.306s
user    0m1.112s
sys     0m0.192s
# time aptitude forbid-version 1234
Package not found: 1234, from 1234       

real    0m1.313s
user    0m1.144s
sys     0m0.164s
#

Even searching through all package descriptions is not slower:

# time aptitude search '?description(1234)'

Can you check if that issue is still present for you? Otherwise I'd
just close this bug report.

Actually I can't even reproduce #697724 (reported by myself back then)
anymore, at least not noticably, so maybe all GzipIndexes related
issues are gone now. Will later check on a much slower machine (an
EeePC 900).
