    Hi!

I am trying to optimize YDB database (https://github.com/ydb-platform/ydb) with Bolt. I have run YDB binary (`ydbd`) with `perf record`, then I want to convert it to Bolt format with `perf2bolt`. Unfortunately, `perf2bolt` uses more than 30 Gib RAM and is OOM killed since I have only 32 Gib RAM.

Is there a way to reduce memory usage?

My setup:
- OS: Fedora 37
- Linux kernel: 6.2.7
- Compiler: clang-15 from Fedora packages (clang 15.0.7 (I've patched a few sources to support this compiler)
- Hardware: Ryzen 9 12 cores, 32 Gib RAM, SSD
- Bolt version: built manually from the main branch with Clang 15.0.7 in Release mode

A related issue in YDB upstream: https://github.com/ydb-platform/ydb/issues/140
